Problems solved by technology

[0003] During production and operation, once the superheater tube of the CDQ boiler is damaged, the leaked water or steam will enter the CDQ along with the circulating gas, and will react with the hot red coke, resulting in H in the circulating gas. 2 and CO content rise sharply, if no corresponding measures are taken, an explosion accident will occur
Harm equipment and personal safety, seriously affect the normal operation of the production system, and bring great hidden dangers to production and safety

Abstract

The invention discloses a method for preventing a dry quenching boiler superheater from being damaged. The method adopts effective protection and treatment measures, ensures stable operation of production of a dry quenching system, eliminates potential safety hazards, and has obvious economic benefits and wide application prospects.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a method for preventing damage to a dry quenching boiler superheater. Background technique [0002] CDQ boiler is a special waste heat boiler, which is an important part of CDQ system. The inert circulating gas is sent to the heat pipe heat exchanger through the circulating fan to cool down to 130°C and enters the dry quenching furnace for heat exchange with coke. After exchange, the temperature drops to about 160°C, and then enters the secondary dust collector to further separate the fine coke powder, and finally returns to the circulation fan, thus completing a cycle. The steam produced by the CDQ boiler is sent to the steam turbine to generate electricity. The CDQ boiler is the center of energy conversion and recovery, and an important link to ensure the stable operation of the CDQ furnace. [0003] During production and operation, once the superheater tube o...
