Gas Turbine Considerations in the Pulp and Paper Industry

Abstract

The pulp and paper industry is one of the largest users of energy in the industrial arena. Large quantities of process steam and electrical energy are required per unit of production. The pulp and paper industry has recognized the thermodynamic benefits and potentially attractive economics of developing power generation as an integral part of their power plant systems. The large requirements for process steam combined with process by-products and wood wastes make steam turbines a serious consideration in plant locations where suitable economic conditions are present. And many systems incorporating a wide variety of steam turbine types have been installed and are contributing toward profitable operations. In recent years, competitive pressures, environmental concerns, the cost and availability of various fuels, and new power generation opportunities have awakened the interest in power generation in the pulp and paper industry, as well as others. A strategic review of these issues creates the opportunity to favorably position the pulp and paper industry for the coming century. The industry has also become aware that gas turbine-based cogeneration systems can frequently be highly desirable relative to their traditional steam turbine approach.
