Abstract
The reduction of NOx emission by the reburning mechanism using natural gas added to coal-fired utility boiler of Israel Electric Corp (IEC) was studied. The reburning mechanism was activated in the flame field when a reducing environment was present; this could be achieved by adding natural gas or other fuels to the flame. An important aspect is to assess the retrofitting required in existing IEC boilers by replacing a fraction of the coal by natural gas. This would also allow purchasing coal with a wide range of parameters, which might be cost effective. Mixed gas-coal burning would benefit both economically and environmentally. Extensive simulations have shown that there is a significant reduction of NOx emission, with addition of relatively small amounts of gas fuel. In parallel, experiments in a coal-fired test facility of 50 kw were conducted that indicated exactly the same trends of NO reduction when LPG was fired downstream in the coal furnace. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
