Parametric Economic Analysis of Natural Gas Reburn Technologies. Topical Report,June 1991-June 1992

摘要

The report presents a parametric economic analysis of natural gas reburntechnologies used for control of nitrogen oxides emissions in coal-fired utility boilers. It is a competitive assessment of the economics of gas reburn performed in the context of regulatory requirements and competing conventional technologies. The reburn technologies examined are basic gas reburn, reburn with sorbent injection and advanced gas reburn. The analysis determined the levelized costs of these technologies in $/ton of NOx removed with respect to a gas-coal price differential in $/MMBtu of energy input. For those niches in which reburn was less economical, a breakeven capital cost analysis was carried out to determine the R&D goals which would make reburn more cost competitive.
