Role of gas and steam turbines to reduce industrial plant energy costs

Data are given to help industry select the economic fuel and economic mix of steam and gas turbines for energy-conservation measures and costs. Utilities and industrials can no longer rely on a firm supply of natural gas to fuel their boilers and turbines. The effect various liquid fuels have on gas turbine maintenance and availability is summarized. Process heat requirements per unit of power, process steam pressure, and the type of fuel will be factors in evaluating the proper mix of steam and gas turbines. The plant requirements for heat, and the availability of a reliable source of electric power will influence the amount of power (hp and kW) that can be economically generated by the industrial. (auth)
