Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

The boiler is a Husk fired fluidized bed combustion boiler with underbed firing system supplied by a south based boiler manufacturer. The boiler specifications are 12 TPH, 10.5 Kg/Cm2, saturated steam. When asked about the steam demand of the plant, the plant manager informed that the a maximum of 5 TPH would be the steam demand..

Steam Pressure Reducing Stations - Thermodyne Boile

Pressure reducing stations (PRS) is the arrangement of certain valves which is used to provide the desired steam pressure at user’s end. Steam coming from the Boiler, through the steam line, enters the PRS at a higher pressure and leaves the PRS at reduced (specified) pressure, in this the flow of the steam remains constant. Like Steam Boiler, PRS is also pressure equipment.

Primary Loop Piping is commonly used in boiler heating systems that run needing multiple temperatures or contstant temperature at the hydronic boiler is required. Primary Loop Piping allows non condensing boilers to maintain a heat level in the boiler high enough to allow the boiler …

Steam Piping Best Practices | CleanBoiler.o

Steam Piping Best Practices In the photo to the right, a green-headed PRV (Pressure Reducing Valve) has been installed to reduce the higher pressure steam from the main steam header, to a lower pressure for use in a low pressure application – such as space heating. On the other side of this wall there is a long run of steam pipe; it

Lower Pressure Operation of Boiler than Design

Boilers operated at a reduced pressure in power station lowers the overall heat rate of the power plant. It is found that in a 176 kg/cm2 steam cycle with 540 degree C superheated steam temperature for a 500 MW power plant lowers the overall plant heat rate around 1.2 kcal/hr.

Pipe Sizing Steam Supply andCondensateReturn Lin

Pipe Sizing. Two principal factors determine pipe sizing in a steam system: 1. The initial pressure at the boiler and the allowable pressure drop of the total system. The total pressure drop in the system should not exceed 20% of the total maximum pressure at the boiler.
