Problems solved by technology

However, the current gasification furnaces all adopt positive pressure blast, which cannot feed materials continuously, and can only operate intermittently, so the work efficiency is not high, and residual gas leaks out when raising the furnace and recharging, which is easy to pollute the environment and cause dangerous
Not suitable for occasions with large air volume and continuous air supply

Abstract

A negative-pressure combustion method for gasifying biologic mass features that the gas generated by gasifier is delivered to draught fan and then to next step, or is first delivered to combustion furnace whose fume is cooled and then delivered to draught fan. Its apparatus is composed of gasifier with gas outlet, combustion furnace communicated to said gas outlet, smoke pipe and draught fan. Itsadvantages are continuous running, high productivity and no gas leakage.

Description

technical field [0001] The invention belongs to a biomass gasification method and device, more specifically to a biomass gasification method and device burning under negative pressure. Background technique [0002] Make full use of low calorific value straw, firewood, corncobs and other crop resources, save non-renewable energy such as coal and oil, and protect the environment, which is in line with my country's energy and environmental policies. The main components of straw are carbon, hydrogen, oxygen and other elements. The straw is crushed by a hay cutter, such as firewood, corn cob raw coal, etc., without processing, directly into the gasifier, and then into the gasifier through a screw feeder. In an oxygen-deficient state, controlled combustion occurs, and oxidation-reduction reactions occur, and various elements are recomposed into combustible gases such as carbon monoxide, hydrogen, and methane by thermal cracking, and energy is converted from solid to gaseous state....
