Application of reburn techniques for NOx reduction to cogeneration prime movers. Volume 2. Lean-burn engine application. Final report, June 1984-July 1988
The industrial boiler market was surveyed to ascertain the population distributions of boilers that might be repowered by a gas-fired prime mover. In this repower scheme, the exhaust from a prime mover is used to fire an industrial boiler. A range of typical industrial boiler sizes (25, 50, and 100 MMBtu/hr) was chosen for a technical evaluation of the repowering concept. Potential prime movers were matched to candidate boilers, and performance, physical and cost data were collected on each. From these data, steam rate, temperature profiles, pressure drop, and boiler efficiency calculations were performed. Steam production and overall boiler efficiency were shown to be maintained with acceptable pressure drops and excellent returns on investment with current gas and electricity price structures. An experimental pilot-scale system was shown to achieve 70 percent NOx reduction with acceptable levels of CO and unburned hydrocarbons. Boiler flame stability was shown with the vitiated flue gas down to an oxygen content of 14 percent.
