4.Combustion time- fuel "particles" must be given sufficient time (residence time) in the furnace to achieve complete combustion. Like fuel/air mixing, the required residence time is least for gases and most for large solid fuels: • Gases and fine liquid sprays- 10 - 20 ms burnout • Pulverized fuel (coal, sawdust)- 1 s burnout
2. The splitter is intended to divide the fuel supplied to it in three equal parts. The fuel is pulverized coal; coal is supplied at a known rate TF (measured by known techniques) to the mill 3 through a supply duct 4 and the coal that is pulverized in the mill 3 is entrained in primary air led to the mill through duct 5.
of 1.2 x 106 # stm/hr. Accordingly, the fuel system had a design basis for the 1.1 x 106 boiler rating but with operating capability exceeding a boiler rating of 1.2 x 10 #/hr. The mill offered was a medium speed vertical spindle type, or more specifically, a ring-roller "MPS" design as built by Deutsche Babcock Werke (DBW) in Oberhausen, Germany.

This is known as primary air. In the direct-firing system, primary air is also used to dry the coal in the pulverizer. The remainder of the combustion air (80 to 85%) is introduced at the burner and is known as secondary air. All coals, when exposed to air, undergo oxidation even at room temperature.
Markus Hurskainen, Pasi Vainikka, in Fuel Flexible Energy Generation, 2016. 7.2.3.1 General. Pulverised coal (PC) combustion is the most widely used technology for utility-scale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace.

The main challenge to ensure optimal operating conditions for boilers is to provide the proper excess air for the fuel combustion. It is generally agreed that 10% excess air provides the optimum air-to-fuel ratio for complete combustion. Too much excess air causes higher stack losses and requires more fuel to heat ambient air to stack temperatures.
