PRM Energy Systems has supplied biomass gasification technology to power producers, industries, and governments. The PRME gasification systems are available in a range of models to gasify 200 to 2,000 tons of biomass fuels.
The PRM gasifier first used biomass fuels and converted waste into clean hot gas. The gasifier used the following fuels: cotton seed hulls, cotton gin waste, rice hulls, rice straw, green bark, saw dust and chips, peat, wheat straw, corn cobs, peanut hulls, chicken litter and pellets.
The PRME gasification systems consists of a solids infeed control, a fuel metering bin, multi-zoned gasification air, staged combustion air, combustion chamber, ash discharge conveyors, and KC reactor. The electronics and instrumentation control present in the system provides manual or automatic operation. The biomass fuels are supplied to the reactor from the fuel metering bin. The bin consists of a variable outfeed conveyor, an infeed leveling conveyor and level switches. The control system automatically adjusts the speed of the outfeed conveyor to maintain the temperature in the reactor. The biomass fuels are transferred into the reactor by a screw conveyor.
The control system in the PRME gasification system provides a PLC based logic control along with interface stations. Protective devices in the gasification system are provided to control, monitor, and for interlocking and alarming purposes. The system communicates with the plant control system with the help of a modular bus communication link.
