rice husk biomass 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.
Technical advantages 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.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
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.
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.
Biomass gasification system is characteristic of small land requirement and environment friendly. It’s one of the most effective way of biomass utilization. Necessary Requirement of Rice husk can be used in POWERMAX Rice Husk Gasification Power Plant: Humdity of rice husk less than 20%.
ricehusk.com Pte Ltd specialises in agricultural commodities and in particular rice husk sourcing, brokering and selling in ground and briquette format to Asia and Europe; mainly to biomass (Co-gen and 100%) user power groups.
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 gasification is based on rice husk as a fuel. Before entering the biomass gasification furnace, the water content of the rice husk must be reduced to less than 20%, and the rice husk can be pyrolyzed and oxidized in the fluidized bed gasifier. The gas production is depended on the quantity of the raw material.
Rice husk as a biomass fuel Rice husk is a by-product of rice growing. The prevalence and year-round production of rice crops on both an industrial and small scale means that rice husks are an attractive biomass fuel because they are not only readily available in large quantities but are also easy to collect. Furthermore, combusting the husk solves
The uses for rice husk are continually growing. Today it is increasingly used as biomass to fuel and co-fuel power plants. There are now many power plants in Asia powered 100% by ground rice husk. ricehusk.com Pte Ltd. is leading the introduction of rice husk into the EU biomass market.
Rice mills powered by the rice husk biomass have significant presence in four provinces – Takeo, Kampong Speu, Kandal and and Kampong Thom. Rice husk is a valuable natural resource that provides a sustainable and abundant source of energy in many Cambodian provinces.
The cultivation of rice results in two major types of residues – Straw and Husk –having attractive potential in terms of energy. Although the technology for rice husk utilization is well-proven in industrialized countries of Europe and North America, such technologies are yet to be introduced in the developing world on commercial scale.
Rice hulls (or rice husks) are the hard protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice husks can be put to use as building material, fertilizer, insulation material, or fuel know as biomass .In the cleaning process, rice plant generates husks which are often burned afield or discarded.
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.
