The burning of bituminous coal produces a common type of fly ash with a very low CaO content, known as class F fly ash (FFA). Lignite and sub-bituminous coal are also used as new power fuels to produce class C fly ash (CFA) with high calcium content (Guo et al., 2017 ). It shows the common FA in Fig. 2 (a) and (e).

The system can be configured to sequentially monitor a number of mills. The SIDOR gas analyzer provides simultaneous measurements of O 2 and CO. An important feature is the stability of the measuring benches, which allows routine adjustments to be made using only ambient air or inert gas. It is the ideal device for safety-relevant measurements.

Bituminous coal is found in veins in sedimentary layers and is one of the two mineral sources of fuel. When processed at a smelter or magma smelter, one unit of bituminous coal produces 9 units of coke. If done at a regular smelter, this processing requires one pre-existing unit of fuel (either charcoal or coke), leaving a net production of 8 fuel.
