To ensure smooth fuel feeding, biomass fuels have to be carefully sized and processed. The moisture content of wood and other biomass waste can vary over a wide range, from 10 percent to more than 60 percent. To ensure steady heat input into the steam losses in wood fired boiler using volumetric feeders, efficient homogenization of fuel with different moisture contents at the fuel yard is a necessity. Horizontal biomass fired steam boiler in Thailand, its rated steam evaporation is among 4 ton to 20 ton each hour. And the two sides of the furnace and its combustion adopts membrane water wall structure whihc is designed by our company independently. It has features of wide range of over load adjusting, wide fuel availibility, wide usage etc.
In this method of combustion, coal fuel is burned in a bed of hot inert, or incombustible, particles suspended by an upward flow of combustion air that is injected from the bottom of the combustor to keep the bed in a floating or “fluidized” state. The scrubbing action of the bed material on the coal fuels enhances the combustion process by stripping away the CO2 and solids residue (char) that normally forms around the coal fuels particles. This process allows oxygen to reach the combustible material more readily and increases the rate and efficiency of the combustion process. One advantage of mixing in the fluidized bed is that it allows a more compact design than in conventional water tube steam losses in wood fired boiler designs. Natural gas or oil fuel can also be used as a start-up fuel to preheat the coal fired steam fluidized bed or as an auxiliary fuel when additional heat is required. Beside, the effective mixing of the bed makes fluidized bed boilers well-suited to burn solid refuse, wood waste, waste coals, and other non standard fuels. The fluidized bed combustion process provides a means for efficiently mixing fuel with air for combustion. When coal fuel is introduced to the bed, it is quickly heated above its ignition temperature, ignites, and becomes part of the burning mass. The flow of air and fuel to the dense bed is controlled so that the desired amount of heat is released to the furnace section on a continuous basis.
Fuels that contain a high concentration of ash, sulfur, and nitrogen can be burned efficiently in rice husk fired fluidized bed steam steam losses in wood fired boilers while meeting stringent emission limitations. Due to long residence time and high intensity of mass transfer, fuel can be efficiently burned in a fluidized bed combustor at temperatures onsiderably lower than in conventional combustion processes (1,400 to 1,600 °F compared to 2,200 °F for a spreader stoker boiler). Rice husk CFB boiler in ZG Boiler adopts automatically adjusted back feeder of high flow rate and low power. The lower temperatures produce less NOx, a significant benefit with high nitrogen-content wood and rice husk biomass fuels. SO2 emissions from wood waste and rice husk biomass are generally insignificant, but where sulfur contamination of the fuel is an issue, limestone can be added to the fluid bed to achieve a high degree of sulfur capture. Fuels that are typically contaminated with sulfur include construction debris and some paper mill sludges. Good price rice hisk CFB boiler is strictly following the standard of ISO9001 Certification.
