summarised in Table 2. Two different runs were carried for the different types of coal. Coal particles that enter the furnace via the coal feed chute drop into the fluidised bed section and start the conversion to gas and char. The char particles move rapidly up and down between the gasification and combustion zones in the bed. The combustion

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...

Gasification of biomass for power generation has only been proven in small scales. Most biomass gasification applications demonstrated to date for electric power have power output less than 10 MW (Heschel and Klose 1995). Biomass is also being investigated for cogasification with coal to reduce fossilbased CO 2 emissions.
