Air Compressor Noise Control Air Compressor Noise Control
AIR COMPRESSOR BY NOISE CONTROL USA AIR COMPRESSOR NOISE CONTROL AIR COMPRESSOR NOISE CONTROL Compressor are often noisy an effective solution is often required to suppress the noise emitted from them. Compressor noise is usually a nuisance because they are sitting on comparatively lightweight structures. The best way to soundproof and to reduce any noise from a compressor regardless of size is to enclose it within a Floor Mounted 4-Sided Soundproofing Acoustic blanket Enclosure. For best results the enclosure should be as large as possible to allow less heat buildup and also to be more effective at reducing the noise output from reaching other areas and acoustically isolating the Compressor to contain structure borne sound being transmitted from where it is mounted. Depending on the current sound levels of the Compressor and your noise reduction goals, an abatement solution can be determined. In most applications a soundproofing blanket enclosure will meet your sound reduction needs. This is a two to four sided soundproofing enclosure with or without a roof. Typically a frame and track is constructed to suspend the soundproofing curtain panels. The soundproofing blankets material is a composite material bonding mass loaded vinyl with an acoustical absorber and faced with a vinyl diamond stitched facing. Using our Soundproofing Acoustic Blankets to construct a 4-sided noise control solution will significantly reduce sound. The noise reduction to be expected is a range of 20 to 40 decibels. The better the construction, weight of blankets and amount of soundproofing acoustic blankets used (the surface area) all factor into your sound reduction numbers. -
Heat Generation Technology Landscaping Study, Scotland's
Heat Generation Technology Landscaping Study, Scotland’s Energy Efficiency Programme (SEEP) BRE August 2017 Summary This landscaping study has reviewed the status and suitability of a number of near-term heat generation technologies that are not already significantly established in the market-place. The study has been conducted to inform Scottish Government on the status and the technologies so that they can make informed decisions on the potential suitability of the technologies for inclusion within Scotland’s Energy Efficiency Programme (SEEP). Some key findings which have emerged from the research include: • High temperature, hybrid and gas driven heat pumps all have the potential to increase the uptake of low carbon heating solutions in the UK in the short to medium term. • High temperature heat pumps are particularly suited for off-gas grid retrofit projects, whereas hybrids and gas driven products are suited to on-gas grid properties. They may all be used with no or limited upgrades to existing heating systems, and each offers some advantages (but also some disadvantages) compared with standard electric heat pumps. • District heating may continue to have a significant role to play – albeit more on 3rd and 4th generation systems than the large high temperature systems typical in other parts of Europe in the 1950s and 60s – due to lower heating requirements of modern retrofitted buildings. • Longer term, the development of low carbon heating fuel markets may also present significant opportunity e.g. biogas, and possibly hydrogen. -
5Th-Generation Thermox WDG Flue Gas Combustion Analyzer
CONTROL EXCLUSIVE 5th-Generation Thermox WDG Flue Gas Combustion Analyzer “For more than 40 years, we have been a leader in combustion gas analysis,” says Mike Fuller, divison VP of sales and marketing and business development for Ametek Process Instruments, “and we believe the WDG-V is the combustion analyzer of the future.” WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as well as CO and methane levels. This information allows operators to obtain the highest fuel effi- ciency, while lowering emissions for NOx, CO and CO2. The zir- conium oxide cell responds to the difference between the concen- tration of oxygen in the flue gas versus an air reference. To assure complete combustion, the flue gas should contain several percent oxygen. The optimum excess oxygen concentration is dependent on the fuel type (natural gas, hydrocarbon liquids and coal). The WDG-V mounts directly to the process flange, and is heated to maintain all sample-wetted components above the acid dewpoint. Its air-operated aspirator draws a sample into the ana- lyzer and returns it to the process. A portion of the sample rises into the convection loop past the combustibles and oxygen cells, Ametek’s WDG-V flue gas combustion analyzer meets SIL-2 and then back into the process. standards for safety instrumented systems. This design gives a very fast response and is perfect for process heat- ers. It features a reduced-drift, hot-wire catalytic detector that is resis- analyzer with analog/HART, discrete and Modbus RS-485 bi-direc- tant to sulfur dioxide (SO ) degradation, and the instrument is suitable 2 tional communications, or supplied in a typical “sensor/controller” for process streams up to 3200 ºF (1760 ºC). -
A Basic Design Approach to Clean Room
www.PDHcenter.com PDH Course M143 www.PDHonline.org A Basic Design Guide for Clean Room Applications Course Content PART – I OVERVIEW Clean rooms are defined as specially constructed, environmentally controlled enclosed spaces with respect to airborne particulates, temperature, humidity, air pressure, airflow patterns, air motion, vibration, noise, viable (living) organisms, and lighting. Particulate control includes: !" Particulate and microbial contamination !" Particulate concentration and dispersion “Federal Standard 209E” defines a clean room as a room in which the concentration of airborne particles is controlled to specified limits. “British Standard 5295” defines a clean room as a room with control of particulate contamination, constructed and used in such a way as to minimize the introduction, generation and retention of particles inside the room and in which the temperature, humidity, airflow patterns, air motion and pressure are controlled. Today, many manufacturing processes require that spaces be designed to control particulate and microbial contamination while maintaining reasonable installation and operating costs. Clean rooms are typically used in manufacturing, packaging, and research facilities associated with these industries: 1. Semiconductor: This industry drives the state of the art clean room design, and this industry accounts for a significant number of all operating clean rooms. 2. Pharmaceutical: Clean rooms control living particles that would produce undesirable bacterial growth in the preparation of biological, pharmaceutical, and other medical products as well as in genetic engineering research.

Aerospace: The manufacturing and assembling of aerospace electronics, missiles and satellites were the first application of clean rooms. -
Suburban Noise Control with Plant Materials and Solid Barriers
Suburban Noise Control with Plant Materials and Solid Barriers by DAVID I. COOK and DAVID F. Van HAVERBEKE, respectively professor of engineering mechanics, University of Nebraska, Lin- coln; and silviculturist, USDA Forest Service, Rocky Mountain Forest and Range Experiment Station, Fort Collins, Colo. ABSTRACT.-Studies were conducted in suburban settings with specially designed noise screens consisting of combinations of plant inaterials and solid barriers. The amount of reduction in sound level due to the presence of the plant materials and barriers is re- ported. Observations and conclusions for the measured phenomenae are offered, as well as tentative recommendations for the use of plant materials and solid barriers as noise screens.

Construction Noise Control Products and Vendors Guidance Sheet
Construction Noise Control Products and Vendors Guidance Sheet Revised: 16 July 2018 Distributed by: New York City Department of Environmental Protection (NYC DEP) The following is intended to provide guidance to construction contractors with respect to finding and selecting suitable construction noise control products. These products and vendors may be helpful to contractors for achieving compliance with the New York City Noise Code, and more specifically, with the Construction Noise Rules found in Local Law 113, Section 24-219, Chapter 28, Title 15 of the Rules of New York City which went into effect in July 2007. While there are similarities in the approach to construction noise control for all work sites, the specific measures and solutions need to be carefully selected and implemented correctly. In general, noise control measures can be applied at the noise source, along the pathway, or at the receiver (listener) directly. For these reasons, it is highly recommended that contractors discuss their situation with a qualified acoustical consultant as early as possible. It is always more cost-effective to design for good acoustics from the beginning rather than to rely on retrofit solutions when noise becomes a problem later. To aid in the selection of an acoustical consultant, links to several national professional societies are provided. The NYC DEP can also provide a list of consultants. This information is not an exhaustive list of noise control products and vendors. It is intended for guidance and informative purposes only, and should not be construed as an official endorsement of any product, vendor, or consultant by the City of New York. -

Humidity in Gas-Fired Kilns Proportion of Excess Combustion
HUMIDITY OF COMBUSTION PRODUCTS FROM WOOD AND GASEOUS FUELS George Bramhall Western Forest Products Laboratory Vancouver, British Columbia The capital and operating costs of steam kilns and the boilers necessary for their operation are so high-in Canada that they are not economically feasible for small operations drying softwoods. About thirty years ago, direct fired or hot-air kilns were intro- duced. In such kilns natural gas, propane, butane or oil is burned and the combustion products conducted directly into the drying chamber. This design eliminates the high capital and operating costs of the steam boiler, and permits the small operator to dry lumber economically. However, such kilns are not as versatile as steam kilns. While they permit good temperature control, their humidity control is limited: they can only reduce excess humidity by venting, they cannot increase it and therefore cannot relieve drying stresses at the end of drying. For this reason, they are usually limited to the drying of structural lumber. Due to the decreasing supplies and increasing costs of fossil fuels, there is growing interest in burning wood residues to pro- vide the heat for drying. Although wood residue was often the fuel for steam boilers, the capital and operating costs of boilers are no more acceptable now to the smaller operator than they were a few years ago. The present trend is rather to burn wood cleanly and conduct the combustion products into the kiln in the same man- ner as is done with gaseous fossil fuels. This is now being done successfully with at least one type of burner, and others are in the pilot stage. -

Large systems for oxygen production and flue gas purification are required for this technology. Air Liquide has been a leader in building large Air Separation Units (ASUs) and more developments have been performed to customize the air separation process for coal-fired power plants. Air Liquide is also actively involved in developing processes for purification of flue gas from oxy-coal combustion systems for enhanced oil recovery applications as well as sequestration in saline aquifers. Through optimization of the overall oxy-coal combustion system, it has been possible to identify key advantages of this solution: minimal efficiency loss associated with CO2 capture (less than 6 pts penalty on HHV efficiency compared to no capture), near zero emission, energy storage, high CO2 purity and high CO2 recovery capability. -

Don't Let Dollars Disappear up Your Chimney!
ENERGY SAVINGTIPS DON’T LET DOLLARS DISAPPEAR UP YOUR CHIMNEY! You wouldn’t leave a window wide open in cold weather. Having a fireplace with an open flue damper is the same as having a window open. That sends precious winter heat and money right up the chimney! Here’s how you can heat your home, and not the neighborhood! KEEP THE FIREPLACE DAMPER CLOSED WHEN THE FIREPLACE IS NOT BEING USED The damper is a flap inside the chimney or flue. It has an open and a closed position. When a fire is burning, the damper should be in the open position to allow smoke to escape up the fireplace flue and out the chimney. When you’re not using the fireplace, the damper should be closed. If you can’t see the handle or chain that opens and closes the damper, use a flashlight and look up inside the chimney flue. The handle could be a lever that moves side to side or back and forth. If a chain operates the damper, you may have to pull both sides to determine which one closes or opens the damper. KEEP YOUR HEAT IN YOUR HOME! Even the most energy efficient homes can fall victim to fireplace air leaks. Your fireplace may be reserved for a handful of special occasions or especially cold nights. When it’s not in use, though, your home loses heat – and costs you money – without you knowing it. Using the heat from your fireplace on a cold winter night may be cozy, but that fire is a very inefficient way to warm up the room.
