Preliminary evaluation of advanced coal-based electricity-generating technologies by means of system-integration analysis
The potential effects of coal-fired cogeneration on the production requirements of the Central Maine Power Company were examined. Two types of cogeneration designs - utilizing a backpressure turbine, the other an extraction turbine - were studied. It was assumed that these facilities were constructed to satisfy the thermal requirements of the Keyes Fibre Company and to produce electricity that could be sold to the electric utility. The analysis included a single-year study of two different capacity-purchase options under consideration by the electric utility. An extended period was also analyzed so that the effects of demand growth and additions and subtractions of capacity on the cogeneration potential could be examined. It was found that some savings of oil could be realized with coal-based cogeneration, and that the quantity of such savings was somewhat dependent on the purchase option, the demand growth rate, and the cogenerator design. It was concluded that both cogenerator designs had some economic viability, but that the backpressure turbine type had a decided advantage due to its significantly lower heat rate.
