METHOD AND SYSTEM FOR PRODUCING A PRODUCER GAS

摘要

Method and system for producing a producer gas The present invention relates to a system (1) and a method for producing a producer gas, wherein the system comprises a first reactor (3) comprising an inlet (5) for receiving a carbonaceous material and air, and for inducing a first swirl to the carbonaceous material and air, a heating module adapted to provide heat such that the first swirl-induced carbonaceous material is pyrolysed and subsequently undergo oxidation and reduction to produce a raw producer gas and a char, and a second reactor (11) adapted to receive the raw producer gas and the char and adapted to combust a portion of the raw producer gas to produce an amount of heat for inducing a reduction reaction of the char to produce a resultant producer gas.
