Industrial boiler system and method for clean combustion of carbon particles

Abstract

The invention belongs to the technical field of environment-friendly energy application, relates to an industrial boiler system and a method for clean combustion of carbon particles, and solves the technical problem of an unreasonable design in the prior art. The industrial boiler system for clean combustion of the carbon particles comprises a raw coal storage, a clean carbon particle milling machine, a powder collection device, a first carbon particle storing tower, a second carbon particle storing tower, an efficient carbon particle combustor, an industrial low temperature combustion boiler and a dust removing device. The industrial boiler system and the method provided by the invention have the advantages that firstly, the clean combustion of coal is realized, timely ignition, rapid combustion and complete burning out of the carbon particles can be ensured, and desulfuration and denitrification devices for flue gas can be omitted, so that the device investment cost as well as the operation and maintenance costs can be saved; secondly, low-temperature combustion of clean carbon particles can be realized, thermal-type NOX is greatly reduced, and low-sulfur and low-nitrogen combustion is realized, so that the purpose of low-sulfur and low-nitrogen emission is realized; thirdly, the coal resources are comprehensively utilized, the economic efficiency is high, especially the utilization ratio of coal such as brown coal is greatly increased, and waste is changed into treasure.

Description

technical field [0001] The invention belongs to the technical field of energy and environmental protection applications, and relates to coal clean combustion technology, in particular to a carbon particle clean combustion industrial boiler system and a carbon particle clean combustion method. Background technique [0002] In recent years, smog, acid rain, and dust pollution incidents have occurred frequently, seriously affecting people's production and life. Coal is an important energy source for industrial production in our country, but serious pollution problems have occurred in the process of its mining and utilization. How to efficiently use resources and minimize pollution has become an urgent task before us. In addition to producing a large amount of smoke and dust when coal is burned, harmful substances such as carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen oxides, organic compounds, dioxins, and smoke will also be formed during the combustion process.

AI Technical Summary

Problems solved by technology

[0005] Although said scheme has reduced coal-burning pollution to a certain extent, there are still following technical problems: 1, the quality requirement of coal is higher, it is difficult to utilize the coals of types such as lignite, and the utilization rate of coals such as lignite is relatively low. Low, it is difficult to make full use of coal and maximize its value

2. The overall equipment is complex, the cost is high, the degree of automation of the work is low, and the labor intensity of the operators is high

3. In the process of coal combustion, the discharge of pollutants is still difficult to achieve a more ideal situation
