Abstract

A method for burning hard coal includes setting four lines of burners formed by primary air ejector on wall of bottom firepot at boiler and setting another four lines of burners formed by secondary air ejector at four corners of firepot, setting two said air ejectors on the same level to form two concentric tangent circular rotary movements of internal and external in boiler by jet flows formed by primary and secondary airs, wrapping primary air by secondary air, setting tertiary air and burn-out air ejector at corners on top of master combustion region to form four-corner tangent-direction jet flow.

Description

technical field

[0001] The invention relates to a method used in the field of energy technology, in particular to an anthracite combustion method. Background technique

[0002] my country's energy production and consumption have always been dominated by coal. The proportion of low-volatility poor-quality lean coal and anthracite coal in power coal is increasing day by day. To burn this kind of coal, it is necessary to solve the problem of ignition, stable combustion, prevention of slagging, and improvement of combustion efficiency. Issues such as exhaustion. Most of the boilers burning low-volatile coal in my country adopt the traditional four-corner tangential combustion method, and it is difficult to comprehensively solve the above problems. At present, some combustion technologies have been developed in China mainly aimed at solving the problems of ignition and stable combustion, especially the thick-lean combustion technology, which is more effective for high-volatile co...
