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.
The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.
Burning hydrocarbon fuels produces carbon dioxide. Incomplete combustion creates poisonous carbon monoxide. Some of the products from burning fuels dissolve in rain water to form acid rain.
Problem soot is caused by improper combustion, which might be caused by low gas pressure or a dirty burner. If the flame appears solid yellow instead of having a bright blue inner flame, it is
If insufficient oxygen is introduced into the furnace, incomplete combustion of fuel will occur. This wastes fuel, causes air pollution, and results in hazardous conditions in the boiler. The unburned fuel may ignite in the boiler and result in secondary combustion, causing a dangerous explosion.
the lack of complete burning because of an inadequate supply of combustion air to the fuel-burning equipment. Improper Mixing of Combustion Air and Fuel. The improper mixing of combustion air and fuel is most likely to occur because of the adjustment of certain components that comprise the burner.
Sep 03, 2019· I have a Worcester Danesmoor CF 15/19 oil fired boiler with Electro Oil Inter B9 burner. Occasionally there is a strong smell of combustion fumes in the kitchen where the boiler is located, and outside the house. The smell is like unburned fuel. This only happens occasionally, at other times there is no smell at all!
The usual arrangement is to have a fuel oil supply available on site, and to use this to fire the boiler when gas is not available. This led to the development of ‘dual fuel’ burners. These burners are designed with gas as the main fuel, but have an additional facility for burning fuel oil.
When a gas fired burner is burning fuel properly a) it will have a blue flame with short yellow tips b) the furnace will pulsate c) there will be no turbulence d) it will have a long bright yellow flame e) the induced draft fan can be shut off
The strength of boiler steel and welds drops sharply at temperatures above 800 degrees Fahrenheit. If a boiler has enough water, the steel will never reach …
