Assessment of pulverized-coal-fired combustor performance. Seventh quarterly technical progress report, April 1-June 30, 1982
There are substantial economic incentives to explore the possibility of converting boilers and other industrial processes from natural gas or oil to pulverized-fuel firing; however, such a change can have a considerable impact on the thermal performance of the system, due mainly to: fuel specific adiabatic flame temperatures; different flow and combustion patterns in the furnace; differences in the type and concentration of radiative species, especially particles, in the combustion products; and ash deposition on heat transfer surfaces. This program is concerned with the provision of a technology base to expedite the conversion of industrial processes from oil and gas to coal and other pulverized fuels. It addresses primarily the impact of fuel type on the thermal performance of a combustor. The program incorporates two experimental tasks and is constructed around an analytical task (Task 1) which will identify and upgrade a family of computer programs required to undertake thermal performance analysis studies. These analytical tools will thus be used to predict the effects of parameters such as fuel type and furnace variables on combustor performance, and to identify those properties which have a major impact on thermal performance. The second task uses a combustion reactor to screen the key variable identified in Task 1 and to provide data on the properties of coal particulate matter which affect heat transfer performance. Verification of the engineering analytical approach will be provided by measurements made in a pilot-scale furnace in the third task.
