Gasifier fluidized bed air gasification of solid fuels

摘要

A fluidized bed gasifier for the gasification of solid fuels, the air applies to the units for the thermal processing of solid fuels and can be used for artificial gas. The gas generator includes a housing with a gas distribution grid, the process gas collection chamber and the gasification chamber placed therein with vapor pipes with nozzles provided with devices for discharging the process gas and combustion products. To maximize the power of the gas generator for heat of combustion gasification products at the lower ends of tips vents installed removable sleeves, the total area of ​​the input horizontal sections of which is 0,90-0,95 of the area located at the same level of the horizontal section of the gasification chamber, which provides the optimum ratio fractions obtained between the gas coming to the consumer and in the flared top of the bed to maintain autothermal process.
