Title:
COAL-AMMONIA MULTI-FUEL FIRED BOILER CONTROL DEVICE, COAL-AMMONIA MULTI-FUEL FIRED BOILER CONTROL METHOD, AND COAL-AMMONIA MULTI-FUEL FIRED BOILER CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/057819
Kind Code:
A1
Abstract:
A coal-ammonia multi-fuel fired boiler controlled by a coal-ammonia multi-fuel fired boiler control device can independently adjust the respective flow rates of first combustion air mixed with a coal fuel jetted from a coal fuel jetting nozzle and second combustion air mixed with ammonia jetted from an ammonia jetting nozzle. The coal-ammonia multi-fuel fired boiler control device acquires an index parameter related to the ignition position of the coal fuel jetted from the coal fuel jetting nozzle, and adjusts the flow velocity of the second combustion air to be increased when the index parameter is equal to or less than a preset specified value.
