In updraft gasifiers, gas is drawn out of the gasifier from the top of the fuel bed while the gasification reactions take place near the bottom. As the producer gas passes through the fuel bed, it picks-up volatile matter (tars) and moisture from the fuel. Therefore, the gas from the updraft gasifier contains condensable volatiles. The design and operation of the gasifiers is such that the gas comes out at 200-400 C temperature. At this temperature, most of the volatile hydrocarbons are in vapor form, which add to the energy content of the gas.

Fixed bed updraft gasifier when supported with cyclone separator, wet scrubbers, bag filters, electrostatic precipitator etc. can deliver clean producer gas which can be used to fire I C Engines which in turn can generate electric power when coupled with generator.
