Dual biomass gasifier with carbonaceous absorbent and apparatus having the dual biomass gasifier

摘要

Dual biomass gasification reactor of the present invention, the first reactor for gasifying the injected waste by using an external heat source and the heat source of the waste itself, and is installed in communication with the first reactor using a heat source of the first reactor and the inside A second reactor filled with a certain amount of carbon adsorbent to reduce the content of tar in the product gas produced in the first reactor, increase hydrogen production, and supply it to a subsequent process, the first reactor having a certain amount of sand therein; Is filled and flows along the air stream of an external heat source to assist in the combustion of waste gas and produce biochar, and in the communication site between the first and second reactors, the second reactor of biochar in the first reactor A filter is installed which prevents flow to the side and prevents the outflow of the carbon adsorbent in the second reactor toward the first reactor. The present invention adopts a dual biomass gasification reactor having a separate internal reactor therein or consists of two stages of reactors and contains a carbon adsorbent in the upper reactor, thereby significantly reducing the tar content in the generated gas to produce power. There is an effect that can produce a high calorific value gas having a low content of tar that can be used stably.
