Problems solved by technology
[0006] The purpose of the present invention is to solve the common problems of energy conversion and low utilization efficiency in existing biomass gasifiers, unstable system operation, and poor gas quality, especially the high content of solid particles and tar in the gas, which makes the post-treatment system complicated and difficult. In order to avoid the secondary pollution of the environment, a biomass gasifier and its gasification operation method are proposed, which can make the gasification reaction more controllable and more flexible, and can effectively improve the gasification conditions and make the gasification reaction more uniform Adequate, can avoid the waste of heat caused by the high reaction temperature of the gasifier, improve the thermal efficiency and gasification efficiency of the reactor, reduce the tar content in the gas, and improve the quality of the gas

A biomass gasification furnace and its gasification operation method belong to the technical field of energy conversion equipment. The reaction furnace body is provided with a drying area, a cracking area, an oxidation area, a reduction area and an ash room in sequence from top to bottom; the oxidation area is equipped with There is a Y-type cracked gas isolation and diversion device. The Y-type cracked gas isolation and diversion device is equipped with a circular tangential air supply device in the oxidation zone. Movable grate, the top of the reduction area is equipped with a circular tangential air supply device in the reduction area; the ash chamber is rolled from three layers of heat-resistant steel plates and welded with the upper and lower flanges, which can make the gasification reaction more controllable, The adjustment is more flexible, which can effectively improve the gasification conditions, and the gasification reaction is more uniform and sufficient, which can avoid the problem of heat waste caused by the high reaction temperature of the gasification furnace, improve the thermal efficiency of the reaction furnace, improve the gasification efficiency, and reduce the fuel consumption. Medium tar content improves gas quality.
Description
technical field [0001] The invention belongs to the technical field of energy conversion equipment, and relates to a gasification furnace and a gasification operation method, in particular to a biomass gasification furnace and a gasification operation method thereof. Background technique [0002] The grim reality of energy and environmental issues is forcing human beings to find a sustainable development path that coordinates population, economy, society, resources and the environment. Among them, the development of new and renewable energy has become a top priority. Biomass includes animals, plants, microorganisms and their derivatives, excretion, and metabolic organic matter. Biomass energy is a form of energy stored in organisms as chemical energy directly or indirectly through photosynthesis. It is the only energy that can be stored and transported. of renewable resources. Biomass can be regenerated in a short period of time. The total amount of biomass generated global...
