Problems solved by technology

[0002] At present, my country's boilers and kilns are widely used in all walks of life. Among them, coal-fired furnaces are widely used due to their high efficiency and low cost. However, the structure and combustion methods of traditional coal-fired furnaces are unreasonable, and energy waste is caused by insufficient combustion. , the thermal efficiency is low, and a large part of combustibles are directly discharged to the outside, which wastes energy and pollutes the environment. This invention is aimed at the scientific design of the combustion system of the coal-fired furnace and the reform of the furnace structure

Embodiment

[0010] Embodiment, a kind of coal-fired furnace three-time aerobic oxidation combustion method, is to adopt mechanical coal feeding device to send coal continuously and evenly into the furnace according to the amount of coal required for furnace combustion, and the high temperature generated in the furnace by primary air combustion makes the coal naturally Gasification, coking, combustion, the combustibles such as carbon monoxide and sulfur dioxide produced are mixed and combusted through the forced air intake at multiple points and different angles in the furnace, and the flue gas passes through the forced air intake of the tertiary air perforated plate tube burner at the fire outlet of the furnace. The wind is mixed, so that the combustibles produced by burning coal in the furnace can be fully burned in the state of high temperature and high oxygen, and the emission of exhaust gas is reduced.

[0011] The gas discharged by the combustion method of the present invention can re...

Abstract

The triple oxygenizing gasification combustion method for coal-fired furnace adopts mechanical coal-feeding equipment to continuously feed the coal according to the combustion requirements for furnace combustion. The high temp. produced in the furnace by primary air combustion can make coal implement natural gasification, coking and combustion, and the carbon oxide and sulfur dioxide inflammable matters are passed through secondary pultipoint different angles in the furnace cavity and mixed with air, and passed through third air porous plate tube combustor, and can be fully combusted, so thatit can make coal obtain full combustion to raise thermal efficiency, but also can protect environment. Said invention is applicable to various boilers, furnaces and kilns.

Description

1. Technical field [0001] The invention belongs to the technical field of combustion of coal-fired furnaces, and in particular relates to a method for tertiary oxygenation and oxidation combustion of coal-fired furnaces. 2. Background technology [0002] At present, my country's boilers and kilns are widely used in all walks of life. Among them, coal-fired furnaces are widely used due to their high efficiency and low cost. However, the structure and combustion methods of traditional coal-fired furnaces are unreasonable, and energy waste is caused by insufficient combustion. , the thermal efficiency is low, and a large part of combustibles are directly discharged to the outside, which wastes energy and pollutes the environment. The present invention is aimed at the scientific design of the coal-fired furnace combustion system and the reform of the furnace structure. 3. Contents of the invention [0003] The object of the present invention is to improve the deficiencies of th...
