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.
Rice husk fired hot water boiler is single drum water tube and fire tube boiler, combustion equipment is chain grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. Except the rice husk, the rice husk fired hot water boiler could also burn other biomass fuels, such as wood

Rice Husk Biomass Steam Boiler in Indonesia 2016-07-07 16:54:45. Indonesia has abundant agricultural, like corn, cassava, peanuts, rice husk, etc. These agricultural waste can be used as biomass fuel in boilers. The rice husk is very rich and many Indonesian prefer to use a rice husk boiler in their production, low cost and money savings.
File Size: 390KB Jan 04, 2020· Rice husk ash, the byproduct of rice husk power plants, can be used in the cement and steel industries further decreasing the need to import these materials. Rice straw can either be used alone or mixed with other biomass materials in direct combustion.
rice husk boiler in malaysia - kuurnsezichten.be. 2019-4-26 · Rice husk or rice hull, as the by-product of rice processing, is a good bio-fuel for the biomass fired boiler, and the boiler can be called rice husk fired boiler. Rice husk fired steam boiler is high efficient, energy conversation and environmental friendly that widely used by rice
Rice husk pellet is a kind of biomass material pellet. It is made of rice husk or rice hull, which is the outer layer of the paddy grain. Rice husk is with deficiencies of soft, light and low in caloricity. After pressed by the biofuel pellet mill, rice husk has become the high caloricity biofuel pellets — rice husk pellets.
The rice husk gasification and pyrolysis experiments were carried out in a laboratory-scale fixed-bed reactor. To obtain the basic data for development of the rice husks gasification process, gasification experiments were also conducted in a bench-scale downdraft type (0.4 TPD (tons per day)) reactor ().The syngas was analyzed using gas chromatography (Perkin-Elmer, Model 5100) and FTIR
Jul 18, 2019· The cultivation of rice results in two types of biomass residues – straw and husk – having attractive potential in terms of energy. Rice husk, the main by-product from rice milling, accounts for roughly 22% of paddy weight, while rice straw to paddy ratio ranges from 1.0 to 4.3.
Hurst Boiler & Welding Co., Inc manufactures its biomass boiler systems with an extended burn chamber, increasing dwell time for the combustion of any unwanted particulates and emissions before they are able to exit the system, making the process much cleaner, which reduces maintenance time and costs.
Gasification is the process of converting rice husk to synthesis gas (syngas) in a gasifier with controlled amount of air. Syngas can be used as a heat source for drying, cooking, etc., or in a cogeneration system for producing electricity. The gasification process can be described in two steps.
