Problems solved by technology

However, there are generally two problems in industrial pulverized coal combustion technology: first, it is impossible to use low-volatile coal that is not easy to catch fire; second, it is impossible to use boilers with smaller capacity
Dense phase conveying makes the combustion air in the primary air insufficient, and the unheated air cannot evenly disperse the pulverized coal
The flue gas temperature at the boiler outlet is already relatively low, and the air cannot be preheated to the temperature required for pulverized coal combustion

Abstract

A rapid combustion type industrial powder combustion system is characterized by comprising a gas-solid premixing combustor, a heat-resistant steel hearth and a high-temperature air preheater. By means of the system, pulverized coal is rapidly ignited, stably combusted and thoroughly combusted in an industrial boiler. A combustion method is provided for clean utilization of coal in the field of the industrial boiler.

Description

technical field [0001] The invention relates to a system in the field of industrial boiler combustion, in particular to a fast-burning industrial powder combustion system. Background technique [0002] Coal is the main component of domestic primary energy consumption, and its clean utilization degree will have an important impact on the environment. Industrial boilers are the main equipment for using coal, and their combustion systems determine whether coal can be used efficiently and environmentally friendly. [0003] At present, the domestic industrial pulverized coal combustion system is gradually replacing the traditional chain grate combustion technology and becoming the main combustion equipment for industrial boilers. The industrial pulverized coal combustion system has the advantages of high combustion efficiency, less smoke emission, easy desulfurization and denitrification. However, there are generally two problems in industrial pulverized coal combustion technol...
