Title: The demonstration of an advanced cyclone coal combustor, with internal sulfur, nitrogen, and ash control for the conversion of a 23 MMBtu/hour oil fired boiler to pulverized coal

Abstract

The project objective was to demonstrate a technology which can be used to retrofit oil/gas designed boilers, and conventional pulverized coal fired boilers to direct coal firing, by using a patented sir cooled coal combustor that is attached in place of oil/gas/coal burners. A significant part of the test effort was devoted to resolving operational issues related to uniform coal feeding, efficient combustion under very fuel rich conditions, maintenance of continuous slag flow and removal from the combustor, development of proper air cooling operating procedures, and determining component materials durability. The second major focus of the test effort was on environmental control, especially control of SO{sub 2} emissions. By using staged combustion, the NO{sub x} emissions were reduced by around 3/4 to 184 ppmv, with further reductions to 160 ppmv in the stack particulate scrubber. By injection of calcium based sorbents into the combustor, stack SO{sub 2} emissions were reduced by a maximum of of 58%. (VC)
