The Gasifier unit is essentially a chemical reactor, where several thermo chemical processes such as pyrolysis, combustion, and reduction take place.
An Updraft Gasifier has clearly defined zones for partial combustion, reduction, and pyrolysis. Air is introduced at the bottom and act as counter current to fuel flow. The gas is drawn at higher location. The updraft gasifier achieves the highest efficiency as the hot gas passes through fuel bed and leaves the gasifier at low temperature. The sensible heat given by gas is used to preheat and dry fuel.These gasifiers are best suited for applications where moderate amounts of dust in the fuel gas is acceptable and a higher flame temperature is required. Typical applications where the updraft gasifiers have been successfully used are:
- Packaged Boilers
- Thermic Fluid heaters
- All kinds of Fryers
- Rotary type roasters
- Aluminum Melting /Annealing Furnaces
