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 distribution of heat input and steam absorption during the normal 32 MW(t) plant output at 100 percent load is as follows: MW(t) Heat Input La Mont boiler 20 PYROFLOW r7 37 Steam Generated La Mont boiler 25 PYROFLOW water wall _7_ Total 32 Note: Boiler efficiency = 86 percent.

How to Calculate Boiler Heat Input Rate | Scienci

Divide this heat gain by the length of time for which the boiler runs, measured in second. For example, if the boiler runs for 1,800 seconds, dividing 12,558,000 by 1,800 gives 6,977, or a little under 7,000. This is the heat input rate, measured in joules per second, or Watts.

Investigation on the heat transfer coefficient a

The first international 350 MW supercritical CFB boiler with a polygonal furnace was put into operation successfully in February 2018. The schematic arrangement of the 350 MW supercritical CFB boiler with a polygonal furnace is shown in Fig. 1.This boiler is characterized by a polygonal furnace, a single air distribution plate, three steam-cooled cyclone separators and three parallel loop seals.

Fluidized Bed Boiler - an overview | ScienceDirect Topi

The excess air coefficient at the furnace exit of a typical CFB boiler is 1.2, and the sectional superficial gas velocity is 5∼6 m/s at 850°C, so the furnace cross section heat release rate is 3.6∼4.4 MW/m 2.

Coal-Fired Performance and Co

Boiler feedwater is pressurized with a single HP boiler feedwater pump (BFP), powered by an electric drive for the 400- and 600-MW cases and a steam turbine drive for the 900-MW case. For steam turbine-driven cases, the exhaust is directed to the LP turbine condenser. A motor-driven BFP is used for the 400- and 600-MW plant sizes
