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.

Conclusions CHARACTERISTICS OF FLUE GASES The characteristics of the flue gases from an incinerator directly affect the design of any waste heat recqvery unit. The most important
Waste incineration is the thermal destruction of waste materials, in a responsible manner. Many types of waste are incinerated including hazardous, industrial, chemical, pharmaceutical medical waste and many others. Waste oils, solvents or other materials that contaminate soil can also be destroyed by thermal treatment of the soil.
waste-heat boilers to incineration. The Betts Avenue plant 01 the City of New York has waste-heat boilers applied to continuous feed incinerators. Because of lon ducts between the furnaces and the boilers, there is n large amount of infiltration. For this reason, high evap' oration cannot be expected.
Author: Jun Liu, Xiaoyu Luo, Sheng Yao, Quangong Li, Weishu Wang Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well
Garbage Incinerator Main disposal method of municipal solid waste includes incineration, composting, and landfill. Incineration is the most effective method, realizing the goal of harmlessness, reduction and resource utilization. After incineration, it can eliminate a lot of harmful germs and to
Waste Heat Boiler. As a necessary part of sulfur recovery unit, the waste heat boiler is a typical fire tube boiler. The multi-pipe mouth of the waste heat boiler is connected with the outlet of the heat reaction furnace, which is both the rear wall of the reactor and the end of the transition zone.
Overview Introduction: We have water-tube and smoke tube two types hazardous waste incineration waste heat boilers. According to the characteristics of waste disposal process, this kind of waste heat boiler takes an extremely important role in reducing harmful substances while adapts well to the waste incineration flue gas.
Hazardous waste and municipal solid waste incineration; Open bottom A type for solid-fuel burning systems; Design features to accommodate high cycling operation . Fire Tube Single Shell, Single Pass. The fire tube single shell, single pass boiler is a simple, …
The boiler feed water economizer is basically a gas-liquid heat exchanger located after the boiler evaporator section. The economizer also uses a portion of the energy contained in the thermal oxidizer combustion gases (after the waste heat boiler) to preheat the boiler feed water before it enters the boiler evaporator section.
Waste Heat Incinerator Boilers In the waste incinerator boiler field, KNM's BORSIG Boiler Systems provides its customers with technologies that mainly serve the burning of waste to generate heat. This includes a wide range of recyclable municipal waste.
