Pulverized Coal Firing Systems Testing & Diagnostics

Pulverisers require substantial maintenance,along with regular testing and frequent adjustment to maintain optimum performance. Typical Pulverized Coal Investigation Scenario: A pulverized coal fired boiler experiences furnace slagging and elevated carbon in ash after changing coal suppliers.Slashing CO2 Emissions from Coal-Fired Thermal Power,,In major coal-fired thermal power plants, pulverized coal-fired boilers are employed as a mainstream solution. Conventional pulverizer for coal can handle only up to 2-3% woody biomass. To solve this problem, a new method was developed to modify a coal pulverizer into a specialized pulverizer for handling woody biomass for combustion. TheThe Role of Coal Characteristics in Boiler Operation,Pulverizer capacity is particularly sensitive to coal moisture. An increase in coal surface moisture An increase in coal surface moisture from 5% to 14% can reduce the output of the pulverizer
