Abstract

The invention discloses a device and a method for realizing clean combustion of solid fuel. The device comprises a combustion device shell, wherein the internal space of the combustion device shell is divided into a reaction chamber and a combustible gas burnout chamber by a high-temperature radiator with a heat radiation function, and a bottom slag hopper is arranged below the reaction chamber; the bottom surface of the reaction chamber is positioned under the high-temperature radiator, the center of the bottom surface is connected with a solid fuel outlet of a fuel feeding device, and the edge of the bottom surface is provided with a collecting hole for ash to enter the bottom slag hopper; the fuel feeding device is provided with a primary air inlet close to the bottom surface of the reaction chamber; a gap for combustible gas to flow into the combustible gas burnout chamber is reserved between the bottom end of the high-temperature radiator and the bottom surface of the reaction chamber; and an air feeding opening for staged combustion is formed in the combustible gas burnout chamber. According to the device, low-nitrogen combustion and low-dust emission can be realized, and efficient and clean combustion utilization of solid fuels such as coal, biomass, petroleum coke, coke, waste plastics, waste rubber and the like can be realized.

Description

technical field [0001] The invention relates to the technical field of solid fuel combustion, in particular to a device and method for realizing clean combustion of solid fuels, which can realize efficient and clean combustion utilization of solid fuels such as coal, biomass, petroleum coke, coke, waste plastics, and waste rubber . Background technique [0002] Solid fuels (coal, biomass, petroleum coke, coke, waste plastics, waste rubber, etc.) have the advantages of wide distribution, low price, and easy access. They are organic fuels that contain chemical energy. It is used as an energy resource and utilized by releasing heat through combustion. Organic solid fuel will release combustible gas at high temperature, and at the same time form solid carbon slag with carbon as the main body, so as to ensure the full combustion of combustible gas and the burnout of solid carbon slag can achieve high combustion efficiency. However, in many cases, due to problems in the combusti...
