Gasification furnace

Abstract

The invention discloses a gasification furnace. The gasification furnace comprises a combustor, a heat exchanger and a smoke sucking box, wherein a cavity structure is arranged between a furnace hearth body and a furnace hearth side plate; furnace heath fins are arranged on the furnace heath body in a surrounding mode; a charge hole is formed in the furnace hearth side plate; a hot air pipeline isarranged on the furnace hearth side plate; a bottom-layer flue tube is arranged at the upper end of the furnace hearth body; heat exchange tubes are arranged inside the heat exchanger main body; medium-layer flue tubes are arranged on the middle parts of the regions of the heat exchange tubes; spiral type heat exchanger fins are arranged on the heat exchanger main body; a heat shielding plate isarranged on the bottom of each medium-layer flue tube; smoke sucking box outer wall fins are arranged on the outer barrel body of the smoke sucking box; smoke sucking box inner wall fins are arrangedon the inner barrel body of the smoke sucking box; and a smoke exhaust pipeline is arranged on the outer wall of the inner barrel body of the smoke sucking box. The whole gasification furnace has height increase of about 3m, and increases hot air area amount as a result of an increased contact surface between the furnace and cold air, so that most hot air generated is sucked into a dryer, and heating efficiency is improved by 30%; and the gasification furnace is of a cylinder structure without a dead angle, is high in safety coefficient, is prolonged in service life and is strong in stability.

Description

technical field [0001] The invention relates to a gas-making furnace, in particular to an environment-friendly, energy-saving, green new energy gasifier. Background technique [0002] At present, most of the existing gasifiers have a square structure, and there are dead corners in the square structure. Cold air cannot pass through the dead corners, and the hot air in the dead corners cannot evaporate, and the fire is easy to burn into the furnace. , poor stability, short service life, the original gasification furnace is manually controlled, and its combustion efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gasifier with high thermal efficiency, strong stability and good cooling effect. [0004] In order to solve the above technical problems, the present invention provides a gasifier, which includes a burner, a heat exchanger and a smoking box, and the burner, heat exchanger and smoking box ...
