12.1 12. Pressure Vessels: Combined Stresses Cylindrical Or Spherical
12. Pressure Vessels: Combined Stresses Cylindrical or spherical pressure vessels (e.g., hydraulic cylinders, gun barrels, pipes, boilers and tanks) are commonly used in industry to carry both liquid s and gases under pressure. When the pressure vessel is exposed to this pressure, the material comprising the vessel is subjected to pressure loading, and hence stresses, from all directions. The normal stresses resulting from this pressure are functions of the radius of the element under consideration, the shape of the pressure vessel (i.e., open ended cylinder, closed end cylinder, or sphere) as well as the applied pressure. Two types of analysis are commonly applied to pressure vessels. The most common method is based on a simple mechanics approach and is applicable to “thin wall” pressure vessels which by definition have a ratio of inner radius, r, to wall thickness, t, of r/t≥10. The second method is based on elasticity solution and is always applicable regardless of the r/t ratio and can be referred to as the solution for “thick wall” pressure vessels. Both types of analysis are discussed here, although for most engineering applications, the thin wall pressure vessel can be used. Thin-Walled Pressure Vessels Several assumptions are made in this method. 1) Plane sections remain plane 2) r/t ≥ 10 with t being uniform and constant 3) The applied pressure, p, is the gage pressure (note that p is the difference between the absolute pressure and the atmospheric pressure) 4) Material is linear-elastic, isotropic and homogeneous. 5) Stress distributions throughout the wall thickness will not vary 6) Element of interest is remote from the end of the cylinder and other geometric discontinuities. -

High pressure rise is developed in the pressure vessel and pressure vessel has to withstand severe forces. In the design of pressure vessel safety is the primary consideration, due the potential impact of possible accident. There have a few main factors to design the safe pressure vessel. This writing is focusing on analyzing the safety parameter for allowable working pressure. The cylinder is designed by considering the pressure, temperature and other constraints. Analysis of strength is made analytically and validation is done by ANSYS model and analysis. Keywords — Air bottle, ASME Code, Finite Element Analysis, ANSYS, Design for Fatigue. 1. INTRODUCTION 2. TYPE OF STRESS INDUCED IN VESSELS Pressure vessels are containers for containment of pressure, Generally there are two types of stresses induced. -

Canada K1P5S9 K1P5S9 EVALUATION OF BOILER CHEMICAL CLEANING TECHNIQUES (AECB Project No. 2.221.1) by Monserco Limited A research report prepared for the Atomic Energy Control Board Ottawa, Canada April 1993 1 Canada Research report EVALUATION OF BOILER CHEMICAL CLEANING TECHNIQUES A report prepared by Monserco Limited under contract to the Atomic Energy Control Board. ABSTRACT Deposits in the secondary side of nuclear steam generators (SG) may cause corrosion and disruptions in steam flow. In the Bruce A reactors such deposits have resulted in the derating of two of the units. Hydrolasing has been successful in removing enough of the deposits to permit operation at 100% power, but a considerable amount of deposit remains in physically inaccessible regions of the generators. The only way to remove these deposits is through chemical cleaning. The EPRI/SGOG process, which has been selected by Ontario Hydro for use at the Bruce A station, is described. This process consists of alternating iron removal and copper removal steps, the two metals which comprise the bulk of the deposit in the Bruce A SGs. The iron removal solvent consists of ethylenediaminetetraacetic acid (EDTA), hydrazine, ammonium hydroxide and a proprietary corrosion inhibitor CCI-801. The copper removal solvent consists of EDTA, ethylene diamine and hydrogen peroxide. Ontario Hydro proposes to dean a bank of four SGs in parallel employing a total of six copper removal steps and four iron removal steps. -

This “International Historic Mechanical Engineering Landmark” now has been incorporated into the laws of state and local jurisdictions of the United States and nine Canadian provinces. The BPVC is in use in 100 countries ASME’S BOILER AND PRESSURE VESSEL CODE (BPVC) 2017 around the world, with translations into a number of languages. The boiler and pressure-vessel sections of the BPVC have long been considered essential within such industries as electric power-generation, petrochemical, and transportation, among others. NUCLEAR ASME has played a vital role in supporting the nuclear industry since its inception, when ASME codes, standards and conformity assessment programs, ASME issued its first Standard, Code for originally developed for fossil fuel-fired the Conduct of Trials of Steam Boilers, in plants, were applied to nuclear power- 1884.

Trade Waste Information Sheet Cooling Towers & Boiler Blowdown
Trade Waste Information Sheet Cooling Towers & Boiler Blowdown Preface Liquid waste generated by industry, small business and commercial enterprises is referred to as trade waste. The Water Supply (Safety and Reliability) Act 2008 prohibits the unauthorised discharge of wastes, other than domestic sewage, into the sewerage system. 1. The definition of trade waste is; - The waterborne waste from business, trade or manufacturing property, other than: Waste that is a prohibited substance; or Human waste; or Stormwater. 2. The definition of Domestic waste is; - Faecal matter and urine of human origin and liquid wastes from sinks, baths, basins, showers and similar fixtures designed for personal hygiene in both residential and commercial properties. Cooling Towers Description of Activity The continuous blowdown, or “bleed off” and other wastewater from both commercial and industrial cooling towers is liquid trade waste. “Comfort and process air-conditioning cooling towers” are defined as cooling towers that are dedicated exclusively to (and are an integral part of) heating, ventilation, air-conditioning or refrigeration systems associated with commercial living space air-conditioning, or commercial process air-conditioning such as computer rooms. The discharge rate from cooling towers in this classification should not exceed 500 L/h. “Industrial Cooling Towers” are cooling towers used in manufacturing for rejecting heat extracted from a manufacturing process. This activity is classified as High Risk and an application must be forwarded to Whitsunday Regional Council. 11. Cooling Towers & Boiler Blowdown Version: 4 Page 1 of 8 Other Issues Commercial and industrial cooling towers generate wastewaters that vary considerably in the contaminants they may contain according to the water treatment utilised. -
Boilers Released 12 December 2017 Trade Waste Discharges from Companies with Boilers Can Harm the Sewerage System
Boilers Released 12 December 2017 Trade waste discharges from companies with boilers can harm the sewerage system. Proper management practices at each site are needed. This guideline outlines the areas of concern and available technologies for the control of these trade wastes. Key trade waste quality requirements Parameter Generally accepted level pH Between 6-12 units Temperature ≤38 degrees C Total Dissolved Solids ≤3500 mg/L Flow rate to sewer Dependant on capacity of receiving sewer Note: Discharge limits may be varied under certain circumstances for individual dischargers. Typical pre-treatment Live or flash steam must never be discharged directly to sewer. Steam boiler or hot water boiler blowdown is cooled below 38 degrees C via a suitably sized blowdown pit or above ground cooling vessel, discharging to sewer via a gully trap. These must have enough retained water volume at ambient temperature to mix with and cool the incoming blowdown. Australian Standard AS3892 - 2001 has more information about blowdown tank design. Heat exchange systems fed from a flash steam vessel can reduce blowdown temperature to an acceptable level. These provide an opportunity for recycling waste heat back to the system. Accumulated solids captured in blowdown equipment are removed as needed for off-site disposal. Boiler water treatment chemicals are stored in bunds, to prevent leaks and spills from reaching the sewerage system. In-ground blowdown pits are covered and finished above ground level to prevent surface or stormwater entry.
