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.
Meanwhile, this type of coal fired boiler is very popular among our customers.Not only because the especially features of it, but also the reasonable price of coal fired steam boiler. READ MORE Coal Fired Boilers for an Oil Refinery in India 2015-08-03 14:16:31. ZG …
Water Usage in Coal to Power Applications The Schematic of a wet recirculating cooling water system for a 520-MW Coal-Fired Boiler. In dry cooling systems the steam exhausted from the turbine is cooled by forcing ambient air across a heat exchanger filled with the condensing steam. There is no loss of water to evaporation or blowdown in
Coal fired boiler is widely used to generate thermal energy by burning fuel in the firebox. Coal can provide lower operating costs in comparison to other fossil fuels like oil or natural gas, it is one of the cleanest fossil fuels available today due to the state of the art computerized pulverized coal handling and combustion technology.
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
This would include boilers fired with raw coal, washed coal, pulverized coal, heavy oil, refuse, wood fueled stoker fired or Fluidized bed design. Coal Catalyst CC-88 is usually mechanically fed or injected into the boiler to create a catalyst bed in the bottom of the combustion chamber.
Coal Fired Boiler . SZL Coal Fired Boiler. SZL Coal Fired Boiler Product Description SZL series coal boiler has the characteristics of big heat surface, high heat efficiency and the squama type chain grate, less coal leakage, respective air chamber and separated adjustment, sufficient and steady burning, outlet dust separator device reduces flue gas drain, frequency control, PLC & DCS auto
Application of Coal Fired Steam Plant Boiler 2016-10-12 16:53:23. Coal, a cheap, ubiquitous and flexible fuel, that’s why it is so popular and taking such a big part in global energy structure. Using the coal to fuel the boiler, that’s the coal fired boiler.
Coal Fired Boiler Applications Suits all industrial applications like dyes, drugs & pharmaceuticals, chemicals, food industry, paper & plywood, agro based industries, dairy and other process industries.
The exergy analysis models constructed for industrial boilers in previous studies , were applicable only to gas-fired boilers and thus, a new exergy analysis model suitable for coal-fired boilers based on previous research is proposed. It should be noted that data from the detailed test of industrial boiler performance are a requirement for this exergy analysis model as shown in Fig. 2.
