Description

Technical field

[0001] The invention relates to a soot blowing device, in particular to an online soot blowing device for a sintering vertical cooling waste heat boiler, belonging to the technical field of sintering waste heat power generation devices. Background technique

[0002] At present, most domestic sintering waste heat power generation systems are pure low-temperature waste heat power generation systems. The system is the hot air taken from the front of the cooling section of the ring cooler, passes through the dust removal equipment, enters the waste heat boiler, and then exchanges with the feed water of the waste heat boiler. Heat, thereby producing superheated steam, and the superheated steam enters the steam turbine generator through the pipe network to generate economic benefits.

[0003] The high-temperature flue gas generated by the sintering shaft cooling furnace at 450°C after a primary dust removal enters the high-temperature evaporator of the waste heat boiler, ...
