Coal-Fired Boilers at Navy Bases, Navy Energy Guidance Study, Phase II and III.
Abstract
Conceptual design and parametric cost studies of steam and power generation systems using coal-fired stoker boilers and stack gas scrubbers in several sizes were performed. Central plants containing four equal-sized boilers and central flue gas desulfurization facilities were shown to be less expensive than decentralized facilities with the four boilers plus scrubbers at diverse sites. Life-cycle costs of steam generation in new central coal-fired facilities were shown to be lower than those for continued burning of fuel oil in existing boilers, when coal costs $30/ton ($1.41 Btu) and oil costs $3.16/million Btu. It is cost-effective to add extra facilities to cogenerate electric power along with steam in new coal-fired systems, compared to purchasing electricity at a price of $0.033 (33 mills) per kilowatt-hour, because ofthe low cost per unit of coal energy. High steam-transmission pressures (600 psia) lead to lower-cost piping systems than lower pressures (300 psia and 100 psia). Coal and waste haul costs are small compared to other system costs.
