Abstract--The experimental results on combustion of Rice husk in a lab scale fluidized bed combustor (FBC), using river sand as the bed material are presented in this paper. The Fluidized bed was operated at 15-25 kg/h of rice husk feed for various excess air factors (20-100%) and for the different fuel particle sizes.
Steam Boiler | Working principle and Types of Boiler … 2019-4-20 · Boiler or more specifically steam boiler is an essential part of thermal power plant. Definition of BoilerSteam boiler or simply a boiler is basically a closed vessel into which water is heated until the water is converted into steam at required pressure.
6. FBC Boilers The combustion gases pass over the super heater sections of the boiler, flow past the economizer, the dust collectors and the air preheaters before being exhausted to atmosphere. Figure 6.4 Bubbling Bed Boiler-2 The main special feature of atmospheric fluidised bed combustion is the constraint
FLUIDIZED BED RICE HULL FIRING BOILER In Thailand who is known as the world top rice producer, huge rice mills are equiped with rice hull firing boiler with steam turbine to generate own electric power from rice husk, their own by-product. There are mainly two(2) system of combustion for rice husk.
6. FBC Boilers Bureau of Energy Efficiency 144 Figure 6.1 Principle of Fluidisation Figure 6.2 Relation between Gas Velocity and Solid Velocity Fixing, bubbling and fast fluidized beds As the velocity of a gas flowing through a bed of particles increases, a value is reaches when the bed fluidises and bubbles form as in a boiling liquid. At

With our competitive approach towards quality, we are able to manufacture and supply a huge stock of Assembly of FBC Boiler.This fluidized bed combustion boiler works on the principle of gaseous exertion created by the burning of solid fuels.
•Bubbling fluidized bed boilers has replaced nearly all small sized solid fuel fired boilers. •It is used to fire - Coal, lignite, anthracite - Bio-mass like wood-chips, rice husk-Garbage incineration, medical waste, sewage sludge etc.
In the cleaning process, rice plant generates husks which are often burned afield or discarded. Thailand is the largest rice producer in the world, and a huge amount of rice husks are utilized as a boiler fuel. Fluidized bed system, either bubbling or circulated, is employed for its combustion.
