  • Comparing Exchangers for Boiler Water/High Temperature Indirect Water Heaters HUBBELL Case Study 1
    HUBBELLHEATERS.COM Comparing Exchangers for Boiler Water/High Temperature Indirect Water Heaters HUBBELL Case Study 1 There are a few different options available if you are looking for a hydronic water heater that uses boiler water or high temperature hot water to heat potable water. One of the biggest decisions regarding boiler water heater types is determining which heat exchanger the system should utilize. Some models use a tube bundle heat exchanger while others use a plate and frame or brazed plate system. Tube bundle heat exchangers and plate and frame/brazed plate systems vary greatly in the way that they heat water and maintain a certain temperature. Both produce hot water, but in different ways. Hubbell offers a wide range of hydronic water heating systems for water to water applications, which can be customized to meet your needs. Let’s take a look at the heat exchangers for hydronic water heaters that should be considered by end users. Tube Bundle Tube bundles are designed to transfer heat from a, boiler water, solar water or high temperature hot water (HTHW) system to the domestic potable hot water system. The primary heat source, in this case boiler water or HTHW, travels through the tubing in the bundle within the shell, and transfers heat to the secondary system (potable water) without allowing either liquid to come into direct contact with the other. Tube bundle heat exchangers are ideal for older non-condensing water heating systems, specifically ones that use oil to produce heat. Older boilers are more suitable for the tube bundle type heat exchanger as they deal with higher non-condensing water temperatures.

  • Boiler & Cooling Tower Control Basics
    Boiler & Cooling Tower Control Basics By James McDonald, PE, CWT Originally Published: CSTR – May 2006 For those of us who have been around boilers and cooling towers for years now, it can be easy to forget how we may have struggled when we first learned about controlling the chemistry of boilers and cooling towers. After running all the chemical tests, where do you start when the phosphate is too high, conductivity too low, sulfite nonexistent, and molybdate off the charts? Even better, how would you explain this decision process to a new operator? Cycles of Concentration The first place you always start is cycles of concentration (cycles). You may measure cycles by measuring conductivity or chlorides. If everything else is running normally, when the cycles are too high, everything else should be proportionally too high. When the cycles are too low, everything else should be proportionally too low. When the cycles are brought back under control, the other parameters should come back within range too. Example We wish to run a boiler at 2,000 µmhos, 45 ppm phosphate, and 40 ppm sulfite; however, the latest tests show 1,300 µmhos, 29 ppm phosphate, and 26 ppm sulfite. The conductivity is 35% lower than what it should be. Doing the math ((45- 29)/45=35%), we see that the phosphate and sulfite are also 35% too low. By reducing boiler blowdown and bringing the conductivity back within control, the phosphate and sulfite should be within their control range too. Boilers 100 Beyond Cycles Whether we’re talking about boilers or cooling towers, we know if we reduce blowdown, cycles will increase, and if we increase blowdown, cycles will decrease.

  • Why Does the Wisconsin Boiler and Pressure Vessel Code, 636 41
    Why does the Wisconsin Boiler and Pressure Vessel Code, SPS 341, regulate air compressors? By Industry Services Division Boiler and Pressure Vessels Program Almost everyone forms a definite picture in their mind when they hear the term “air compressor.” They probably think of a steel tank of some shape and dimension, with an electric motor, and an air pump mounted on top of the tank. To better understand the requirements of the Wisconsin Boiler Code, SPS 341, pertaining to air compressors, we need to have some common terminology. If a person wanted to purchase an “air compressor” at a hardware or home supply store, they would certainly be offered the equipment described above, consisting of three separate mechanical devices; the motor, the pump, and the storage tank. First, there is an electric motor, used to provide power to the device that pumps air to high pressure. This pumping device is the only part of the unit that is properly called an "air compressor." The compressor delivers high-pressure air to the third and final part of the mechanical assembly, the air storage tank; commonly called a pressure vessel. Because the pressure vessel receives pressurized air, this is the only part of the device described above that is regulated SPS 341. SPS 341 regulates pressure vessels when the pressure vessel's volume capacity is 90 gallons (12 cubic feet) or larger, and the air pressure is 15 pounds per square inch or higher. A typical pressure vessel of this size would be 24 inches in diameter and 48 inches long. In industrial settings, it is common practice to mount very large air compressors in a separate location from the pressure vessels.

TROY MT 59935 Installation and Operation Instructions for W-90E W-130E W-180E Because of the very high efficiency of the Seton boiler the flue gas exhaust temperatures can be low enough to cause condensation in the chimney. This condensation may, over time, damage a masonry chimney. If you have condensation in your chimney, a insulated stainless steel chimney liner should be installed inside the flue SAFETY INSTRUCTIONS Safety Notice: If this is not properly installed, a house/building fire may result. For your safety, contact local building or fire officials about permits, restrictions, and installation requirements for your area.

  • Mechanical Systems Water Efficiency Management Guide
    Water Efficiency Management Guide Mechanical Systems EPA 832-F-17-016c November 2017 Mechanical Systems The U.S. Environmental Protection Agency (EPA) WaterSense® program encourages property managers and owners to regularly input their buildings’ water use data in ENERGY STAR® Portfolio Manager®, an online tool for tracking energy and water consumption. Tracking water use is an important first step in managing and reducing property water use. WaterSense has worked with ENERGY STAR to develop the EPA Water Score for multifamily housing. This 0-100 score, based on an entire property’s water use relative to the average national water use of similar properties, will allow owners and managers to assess their properties’ water performance and complements the ENERGY STAR score for multifamily housing energy use. This series of Water Efficiency Management Guides was developed to help multifamily housing property owners and managers improve their water management, reduce property water use, and subsequently improve their EPA Water Score. However, many of the best practices in this guide can be used by facility managers for non-residential properties. More information about the Water Score and additional Water Efficiency Management Guides are available at www.epa.gov/watersense/commercial-buildings.
