Title:
METHOD FOR INHIBITING SLAGGING AND COAL-FIRED POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/150510
Kind Code:
A1
Abstract:
The present invention provides a method for inhibiting slagging and a coal-fired power generation system that are capable of inhibiting the generation of slagging inside a combustion boiler while inhibiting the elution of trace elements from coal ash. This method for inhibiting slagging for a coal-fired power generation system, which is provided with a coal pulverizer 141 for pulverizing coal to manufacture pulverized coal, and a combustion boiler 16 that uses primary air and secondary air supplied at a later stage than the primary air to burn the pulverized coal manufactured by the coal pulverizer 141, includes supplying a slagging inhibitor for inhibiting slagging in the combustion boiler 16 to a region from 825°C to the coal melting point temperature inside the combustion boiler 16 and at a later stage than the combustion location of the pulverized coal.
