Abstract

An organic matter such as sewage sludge ( 101 ) is treated by gasifying the organic matter into a combustible gas and using the combustible gas as a fuel for a gas engine or a gas turbine to recover power (energy). In a method of treating the organic matter, an organic matter as a raw material is dried in a drying process ( 51 ), the dried raw material is gasified to produce a generated gas ( 123 ), and the sensible heat from the generated gas and/or a combustion gas produced by gasification is recovered by using a heating medium in a recovery process. Then, the heating medium heated in the recovery process is introduced into the drying process as a heating medium gas for drying.

Description

technical field [0001] The present invention relates to a method and apparatus for treating organic matter such as sewage sludge: gasifying the organic matter into a combustible gas, and using the combustible gas as a fuel for a gas engine or a gas turbine, thereby recovering power in the form of electricity or the like ( energy). Background technique [0002] Currently, available methods for treating organic matter with a high water content such as sewage sludge (organic matter with a water content of 70% or more) are broadly classified into anaerobic digestion and incineration. Anaerobic digestion can recover energy because it produces methane gas through methane fermentation, but the disadvantage is that this method requires a large digestion tank due to the slow reaction speed, so this method has a problem of increasing the cost of equipment once its reaction state is disrupted , the method takes time to recover, since the method is a biological reaction, and the method...
