Economics of coal utilization for industrial steam generation

OSTI ID:5700528
This paper focuses on coal utilization in new boilers built at existing industrial plants. It considers the economics of coal utilization at moderate scale and load factors. Existing factories with oil- or gas-fired boilers capable of supplying the demand for steam are analyzed in terms of optimum size coal-fired boiler to be deployed, given steam load duration characteristics. Economics of stoker vs. pulverized coal firing are compared. Also analyzed are the economics of including cogeneration capability in such installations. Variables considered in this analysis include: steam demand magnitude, load duration curve, and capacity of existing boilers; value of electricity cogenerated; fuel prices; and remaining facility life and appropriate fixed charge rate. A site-specific example is provided in addition to the parametric analysis.
