Problems solved by technology

[0009] The traditional fixed bed can only be judged by human eyes through on-site duty or remote video monitoring. Once a "funnel" is found, it will be dealt with manually, that is, adding biomass raw materials to the "funnel" to "block" it

Abstract

The invention discloses a biomass gasification fixed bed with the function of preventing burn-through, which belongs to the technical field of biomass energy utilization equipment and includes a furnace body, a material laying device and a multi-point temperature detection device; the furnace body includes an upper cavity and the lower cavity, the upper cavity and the lower cavity are separated by a fire grate; the material spreading device and the multi-point temperature detection device are all located inside the upper cavity, and the multi-point temperature detection device Located below the material spreading device, the material spreading device and the multi-point temperature detection device are respectively connected to the transmission device; The lower grate is rotatably connected with the furnace body, and is used to drive the upper grate and the lower grate to rotate through moving parts. The invention overcomes the traditional mode of on-site duty or installation of remote video monitoring, predicts the combustion conditions in the furnace in advance, predicts the risks of partial burning and burn-through, and prevents problems before they happen.

Description

technical field [0001] The utility model belongs to the technical field of biomass energy utilization equipment, and in particular relates to a biomass gasification fixed bed with the function of preventing burn-through. Background technique [0002] The downdraft biomass gasifier (fixed bed) is to evaporate the volatile matter in the biomass at a high temperature under the conditions of a certain temperature and oxygen supply in an open container with the biomass processed into a uniform particle size. It is cracked into combustible gas with high calorific value, which is sent to gas combustion energy conversion equipment such as boilers and internal combustion engines, and converted into heat energy and kinetic energy. It is widely used in industrial, civil and other fields. [0003] For the gasification of processed biomass raw materials with small particle size and uniformity, a downdraft fixed bed can be used. The fixed bed is characterized by an open or semi-closed cy...
