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.
Steam Systems 6 2. Obtain a composition analysis for each fuel, which will be necessary for calculating fuel usage for a given load. 3. Determine the fuel costs; this is necessary for the economical optimization of boiler room design. For new boiler(s) installation into an existing system, a two-

The advantage of plate type exchangers is that they are more efficient Gas-fired water heaters are more efficient in source energy
Air Force Medical Support Agency Current ETLs published by the Air Force Civil Engineer are available on the Whole Building Design Guide and can be viewed at WBDG.org. 220.127.116.11 Boiler design shall include a dedicated constant volume boiler primary pump to ensure proper water flow at boiler if non‐condensing boilers are utilized or if

File Size: 1MB Hospital boiler systems thus need to be robust enough to produce all the steam necessary to heat the water used in the laundry room. In fact, it’s common for the laundry room of a hospital to have its own boiler separate from the main steam plant, which tells you how much hospital laundry rooms rely on steam from boilers.
Gas cost : The cost of gas is usually stated in the price per therm or price per M or MCF (1,000 cubic feet). In computing costs, the actual total to the end user should be used, and divided by the number of therms used to find the cost per therm. Various rate structures are used by local gas suppliers.
Design of an industrial boiler At full capacity a boiler of this size converts 3 000 litres of fuel oil or a corresponding amount of natural gas to thermal or process heat every hour. This would be sufﬁcient to heat more than 2 000 houses. Because of the huge volume of water and the multi-stage lead-through of

BOILER AND BOILER PLANT OPERATIONS 1. PURPOSE. This Veterans Health Administration (VHA) d irective establishes the policy on the operation of high pressure boilers and boiler plants. AUTHORITY: 38 U.S.C. 7301(b). 2. BACKGROUND. a. Boilers and boiler plants are essential to …
Oct 25, 2016· Case study: hospital boiler systems Early in the design process, the use of heat-recovery chillers was evaluated. Using a contractor partnership, preliminary pricing estimates were made comparing a low-temperature hot-water system with a typical heating-water system. In fact, the gas usage remained so low that the gas meter was checked
Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.
