WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
Waste heat is a valuable resource. Johnston Boiler Company’s line of single and triple pass Waste Heat Recovery (WHR) boilers offer your company a way to save valuable energy, energy typically lost in waste heat. The WHR se-ries are used in petrochemical plants, refineries, steel mills, ore converters, brick or cement plants, glass works, and
Incorporates Worked-Out Real-World Problems. Steam Generators and Waste Heat Boilers: For Process and Plant Engineers focuses on the thermal design and performance aspects of steam generators, HRSGs and fire tube, water tube waste heat boilers including air heaters, and condensing economizers.Over 120 real-life problems are fully worked out which will help plant engineers in …
Waste Heat Boiler And Steam Drum - Student - CheresourcesMar 28, 2020Waste Heat Boiler In Production Of Sulfuric Acid - StudentMay 20, 2012Kettle Type Reboiler As Waste Heat Recovery BoilerSep 25, 2005Design Of Waste Heat Boiler - Student - Cheresources.com See more results Heat recovery boilers are also often found in association with high temperature processes such as steel and glass making. It is not uncommon for these boilers to receive additional heat by supplementary firing of other by-products or by burning gas or light oil to raise the boiler inlet gas temperature to a level commensurate with the desired
the waste heat from the gas turbine exhaust gas, enabling generation of hot water, saturated steam or superheated steam. The WHRU is also capable of heating up thermal oil and TEG, and can be designed to fit individual customer needs and optimum performance. Customer benefits • Customized design • Global service network
Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
Waste Heat Recovery Boilers (WHRB) - Wastetherm is manufactured by Thermodyne- are designed to recover heat from waste flue gases from DG exhaust, Furnace exhaust to produce steam or hot water. WHRB, industrial boilers are advanced enough to deliver max possible heat recovery & save money.
Jan 10, 2010· Waste Heat Boiler Design - posted in Student: Hi all I am a student of 3rd year of Chemical Engineering. I have been asked to design a waste heat boiler present in a previous process design. The process was HCN by BMA process (Degussa). Well the waste heat boiler that I need to design is located just after the catalytic reactor, the process gases leave the reactor at a temperature …
A key component in waste heat recovery is the heat exchanger. The profitability of an investment in waste heat recovery depends heavily on the efficiency of heat exchangers and their associated life cycle costs (purchase, maintenance, etc). Different designs All these factors vary considerably between different heat exchanger technologies.
This program is called HAD-WHRB which can design waste heat recovery boiler under waste gas condition. You can arrange various types of chamer type wall panel, superheater, screen, evaporator and economizer, and it is designed to be horizontal or vertical type. …
A correctional institution in the US awarded Indeck a contract for the supply of a Heat Recovery Steam Generator (HRSG) system with auxiliary equipment to generate steam from waste gas. The Incline HRSG reclaims waste heat from a Centaur 40 gas turbine and supplies 19,200 PPH / 135 PSIG steam to the prison for heating and process users.
In Lees' Loss Prevention in the Process Industries (Fourth Edition), 2012. 12.8.4 Waste Heat Boilers. Process heat recovery boilers, or waste heat boilers, are widely used, particularly on ethylene and ammonia plants and on sulfuric acid and nitric acid plants.This type of boiler has developed as a cross between a conventional shell-and-tube heat exchanger and a firetube boiler.
