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.

Flue Gas - an overview | ScienceDirect Topi

Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of air–fuel ratio. In this chapter, air–fuel ratio is defined by the ratio of their weights; air–fuel ratio of 10

Dec 09, 2015· Sistem udara dan gas buang merupakan system yang yang mendukung terjadinya proses pembakaran di dalam boiler, hal ini dilakukan agar proses pembakaran dapat dikontrol secara optimal sehingga terjadi proses pembakaran yang sempurna dan efisien.


add-on devices if the boiler is designed for optimum flue gas velocities in the first place. Each boiler pass should be designed with a cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing soot build-up within the tubes. When it …

Aug 31, 2015· This Standard specifies the methods for determination of dinitrogen monoxide in flue gas which results from combustion or chemical reaction, etc. and is exhausted through flue, chimney, duct, etc. DIN EN 16497-1 - Chimneys - Concrete System Chimneys - Part 1: Non-balanced flue applications

Generic Boiler Output Formula? - Boiler and Pressu

Jan 30, 2006· Since combustion equation has 3 moles of gas on both LHS & RHS, for exhaust gas can use (NG + combustion air) volume. Only need to correct for temperature per gas law. Best to use the actual exhaust T, but if not available, use 400 o F. The boiler mfr. recommends the stack ID, so from volumetric flow, you get the exhaust velocity.

mechanical engineering - Velocity of flue gases through

1) Guess a velocity, gas pipes are usually about 20 m/s but for flare headers it can go up about 90% of speed of sound. So the range is quite large. 2) Calculate Reynolds number and find friction factor from a Moody diagram. 3) Use the Darcy–Weisbach equation to calculate velocity.
