Airflow and Combustion Characteristics and -

Abstract. In order to solve the problems of lower heating rate of the primary air/fuel mixture and higher NO x emission of the boiler, both the small-scale cold air experiment of a single burner and industrial-scale experiments of the centrally fuel-rich (CFR) swirl burner on a retrofitted 300 MW wall-fired boiler fed with low-volatile coal under deep air staging were performed.

Water-tube boiler - Wikipedia

2019-10-30 · A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
