The coal stream ignition process is critical to the performance of modern pulverized coal burners, particularly when operating under novel conditions such as experienced in oxyfuel combustion.

Pulverised coal and biomass coCombustion: Particle flow modelling in a swirl burner
coal with 15 µm size only has a KSt of 114 bar·m/s. The largest particle size results were <125 µm and the three coals of this size had the lowest KSt in Table 1 in the range 3044. Comparison of coal reactivity as a function of coal composition has to be done at the same mean size and no such data has been published, as can be seen in Table 1.

location of the gas burner in the boiler, above the coal burners. In this "reburning" mode, some of the NOx that has already formed lower down in the boiler is reduced, by a slight deficiency of oxygen, to N 2. The effect of this is that, to meet NOx emissions requirements set for the boiler, 1015% less ammonia solution is required in the SNCR.
Higher content of valuable species of syngas generated by the Combined Burner. Good slagging performance, small heat loss at the wall surface. Be used for the topinjected pulverized coal gasifier.

maintain a steady flame in a laboratory scale burner burning only pulverised coal or atomised liquid fuel and laboratory flames burning non gaseous fuels are commonly supported by cofiring a gaseous fuel. The latter essentially substitutes the quantity of volatile gases, which would have been ideally produced from a coal flame [2].
gasifier syngascooler coal gas to gas treating quench quench gas Figure 2: SCGP systems of Demkolec ICGCC The gasifier consists of a pressure vessel with a gasification chamber inside and operates at some 26 barg. The inner gasifier wall temperature is controlled by circulating water through the membrane wall to generate MP (some 45 barg) steam.
