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. One is known as Yoshimine Boiler design of Inclined moving step grate where rice husk will come in from the top portion of the inclined grate and it roll over downward while combusting, then the husk after its volatile matters are completely burn, will be taken away as carbon. This kind of carbon can find its market in Japan, Germany and others.

If you do not need to sell carbon residue from the rice husk, then we adopt fluidized bed combustion method to completely burn rice husk to fine white ash. Due to the very special characteristics of rice husk which burn in two stages namely first stage of combustion during volatile gas extraction which occur instantly after feeding, and the second stage of combustion which takes quite long time to finich burning carbon from the shell, conventional firing method can not be used if complete combustion is required. Fluidized Bed Combustion is considered as the best among all presently available.
