Technical and economic feasibility of diesel engines for stationary cogeneration applications using oxygen-enriched combustion air, water injection, and low-grade fuels was examined. The effects of these modifications on the diesel engine were studied with a computer simulation: results are presented in a companion paper. Four methods of oxygen enrichment, purchases LOX, cryogenic separation, pressure-swing adsorption (PSA), and membrane enrichment (ME) were investigated. Two of these methods, PSA and ME, are particularly amenable to integration with a stationary engine. After the technical evaluation was completed, the economic performance of the options was analyzed. Results show that the economic viability of the system depends primarily on switching to a cheaper, low-grade fuel; the optimum oxygen enrichment is the minimum that will enable the engine to burn the low-grade fuel. Economic benefit also derives from increased power production. Both of the methods that can be integrated with the engine show economic benefits, but one is more attractive that the other. Cryogenic separation systems are generally too large to be technically feasible for this application. The use of low-grade fuels, oxygen enrichment, and water injection affect ignition delay and combustion times, cylinder temperatures and pressures, and emissions (especially smoke, particulates, and NO{sub x}). There appears to be an optimum combination of these parameters that will allow short ignition delay, reasonable cylinder temperatures and pressures, and low emissions.
