Description

technical field

[0001] The invention relates to an industrial kiln combustion system, in particular to an efficient, environmentally friendly and safe powder combustion system for an industrial kiln. Background technique

[0002] my country is a big country of energy consumption. In the total energy consumption of the country, coal accounts for more than 75% and oil accounts for 17%. As the most important thermal energy conversion equipment, boilers are widely used in various industries such as power stations and industries. The thermal efficiency of traditional boilers generally can only reach 80% to 85%. How to improve the thermal efficiency of the existing boiler system is of great significance to my country's energy saving.

[0003] For direct combustion of solid fuels such as coal, there are often deficiencies such as insufficient combustion, low calorific value released, and serious pollution emissions. In order to improve the combustion efficiency, the prior art ge...
