Progress of circulating fluidized bed combustion

NO x emission from a CFB boiler is lower than PC boilers due to its lower combustion temperature. The NO x emission from a CFB boiler is less than 200 mgm 3, and the sulfur retention efficiency by limestone injection into the furnace reaches 9095% [49, 50. The pollutant emissions can meet the emission standards of most countries in the

The role of Circulating Fluidised Bed (CFB) technology

The CFB process for power generation was developed to burn low grade coal or coals that are difficult to burn in a pulverised coal boiler.
