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 Waste Heat Boiler Thermal Efficiency Calculati

The exhaust heat loss is the heat loss caused by a part of the heat that is taken away by the smoke of the boiler. Its size is related to the amount of smoke, the smoke exhaust and the reference temperature and the sensible heat of the water vapor in the flue gas. q2 can be used as a simplified calculation formula: q2 = (3.55αpy +0.44) (tpy-t0

STEP 3 SELECT THE BOILER The size of the replacement boiler will be based on the Total Heat Loss of the building calculated in Step 2. The boiler should be selected based on its Net I-B-R Rating in BTU/Hr. For example, if the Total Heat Loss of the house is 85,000 BTU/Hr. then the Net I-B-R Rating of the replacement boiler must be at least 85,000.

Exhaust Gas Boiler - Waste Heat Boiler - Zhong Ding Boil

Exhaust gas boilers are the significant energy saving equipment, utilize the heat in flue gas from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the exhaust gas boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine

Exhaust Gas Boilers And Economisers working procedure The use of exhaust gases from diesel engine: The use of exhaust gases from diesel main propulsion engines to generate steam is a means of heat energy recovery and improved plant efficiency. An exhaust gas heat exchanger is shown in Figure above.

Heat Recovery from Boiler Exhaust Gases | Physics Foru

Jan 05, 2015· The exhaust gases from a natural gas-fired central heating boiler leave the boiler at a temperature of 70 deg C. The oxygen content of the exhaust gases is 9% by volume (dry). The rate of energy input (Gross calorific value) to the boiler from natural gas is 16kW. The gross calorific value of natural gas is 55MJ/kg.

Boiler Capacity - Engineering ToolB

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as
