Boiler ash deposits generated during combustion of coal, biomass, black liquor, and energetic materials affect both the net plant efficiency and operating strategy of essentially all boilers. Such deposits decrease convective and radiative heat exchange with boiler heat transfer surfaces. In many ca

09 Combustion (burners, combustion systems) 98100548 Experimental and numerical assessment of NO, reduction and char burnout of various South African utility feedstocks Fortsch. D. er al. VDI-Ber., 1997, 1313, (Verbrennung und Feuerungen), 21-26. Five South African domestic coals were investigated with respect to both NO, reduction by air staging and char burnout.
The char burnout experiments were conducted at Eskom using a drop tube furnace in order to adjust the parameters for the char combustion model which is currently used in the MOLOS 3D combustion code. Furthermore, the response of the aforementioned coals to air-staged combustion was investigated. The NO, tests were carried out at a 20 kW furnace at the Australian Combustion Technol.
Center (ACTC). The behaviour of the tested coals varied significantly. In order to study the special behaviour of the coals. a new NO, model, tested against the experimental data, was applied for mathematical modelling using the AIOLOS code.
