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.
emissions between the pilot facility and four coal-fired boilers of different configurations. The pilot furnace was able to simulate the pf burnout for the three full-scale wall-fired and the tangentially fired boilers at elevated excess air levels and under conditions of similitude respectively.
application on a 175 MW coal fired boiler in 1980. MHI transferred their technology through licensing agreement to several companies in Europe and to Cormetech in the United States. Over 319 units including 56 coal fired boilers worldwide operation successfully using this technology. Figure 1 Catalyst for Coal, Oil, and Gas Applications
The coal fired boilers includes chain grate boiler, circulating fluidized bed boiler, and the evaporating capacity can reach to 750 t/h, which can meet the needs of various industries. They are widely used in thermal power plants, Industrial enterprises, chemical factories, pharmaceutical factories, universities, etc
File Size: 1MB Application Note The Opportunity Critical asset inspection and monitoring is a necessity in coal-fired power gen-erators and furnaces where unplanned outages can cause serious efficiency losses. Heat exchange tubes can become deposited with fused ash or ‘slag,’ resulting in inefficient heat transfer, or in serious cases, large clinkers can
What are the sources of heat for the Boiler?The source of heat for a boiler is combustion of various types of fuels such as wood, coal, oil, rice husk or natural gas. Sometimes, Nuclear fissiWhat is the average life of a Boiler?he average life of an industrial boiler is last up to 15 years. If your boiler is reaching at that age milestone than you should start searching foHow much does a new industrial boiler cost?The cost of a boiler depends on several factors such as heat requirement, size, and Indian Boilers Regulations Certificate. 34 Coal Fired Boiler jobs available on Indeed.com.

Overfire air has proven to very effective in corner-fired boilers originally designed by Combustion Engineering (CE)/Alstom, and is the dominant method of NO x control with modern systems. We developed our innovative overfire air system for corner-fired boilers using proprietary computational fluid dynamic (CFD) modeling and experience gained
Cofiring biomass and coal is a time-tested fuel-switching strategy that is particularly well suited to a stoker boiler, the type most often found at coal-fired federal facili-ties. However, cofiring has been successfully demonstrated and practiced in all types of coal boilers, including pulverized-coal boilers, cyclones, stokers, and fluidized
The report provides a methodology for estimating budgetary costs associated with retrofit applications of selective catalytic reduction (SCR) technology on coal-fired boilers. SCR is a postcombustion nitrogen oxides (NOx) control technology capable of providing NOx reductions >90%. With SCR, NOx reductions are achieved by injecting ammonia into the flue gas, which then passes through layers of
