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.
Stoker Fired Boiler are classified according to the method of feeding fuel to the furnace and by the type of grate. The main types of stokers are: Chain-grate or travelling-grate stoker Spreader stoker boiler Travelling Grate or chain grate Stoker Boiler In Travelling Grate boiler coal is fed at one end of a …
Apr 26, 2020· The coal hot water boilers from Keystoker make for a powerful heating option to use in your home, or commercial building. Using anthracite coal to burn, or oil if you purchase a dual fuel kit, this coal burning boiler can produce anywhere from 85,000 to 528,000 BTUs.
Author: Babak Shahri The successful burning of ROM (Run-of-Mine) Coal to efficiently fire a Stoker Boiler has been achieved by a Kinergy Vibrating Grate. It was retrofitted under an existing stoker boiler in Southern Illinois. This 14 ft. (4.26 m) wide by 17 ft. (5.2 m) long Stoker Grate has been in productive use since 2007.
coal fied steam chain grate stoker boiler - Professional . Capacity: 700 - 14000 kw Pressure: 0.8 - 1.0 Mpa Fuel: natural gas, coke oven gas, bio-gas,liquid propane gas, diesel, heavy oil, light oil, crude oil Industries: Petroleum, chemical, chemical fiber, pharmaceutical, textile printing and dyeing, building materials, wood processing, vegetable oil processing and other industries
Chain-Grate or Travelling-Grate Stoker Boiler Coal is fed onto one end of a moving steel grate.2 months 3. these solids encourage foaming and cause carryover of water into the steam. The percentage of impurities found in boiler water depends on the untreated feed water quality. coal travelling grade of boiler stocker; travelling grate coal
The impact of coal quality on the efficiency of a spreader stoker boiler Article (PDF Available) in Journal of the Southern African Institute of Mining and Metallurgy 115(12):1159-1165 · December
By Richard F. Abrams, Babcock Power Environmental Inc. and Kevin Toupin, Riley Power Inc. There is a need for today’s power plants to meet the growing demand for electricity while, at the same
Phases of pulverized coal burning The time of pulverized coal-air mixture in a furnace can be divided into three periods: 1. drying, devolatilization and ignition of coal particles, which requires 0.2–0.3 s, 2. Intensive mixing and burning of pulverized coal-air jet during 0.5–1.5 s on a distance of 1–5 m with formation of flame kernel
Fluidized Bed Combustion Boiler, Stoker Fired Boiler, Pulverized Fuel Boiler, …. The main classifications are spreader stoker and chain-gate or traveling-gate stoker. … As grate moves along the length of the furnace, the coal burns before …
