Over 30,000 hp in two-shaft machine with 38% efficiency
Westinghouse Canada's prototype CW352 2-shaft industrial gas turbine, designed for oil and gas pipeline, process, and marine applications, should be ready for factory testing and in-service evaluation by 1976. Under base-load conditions, a low pressure ratio, and an inlet temperature of 1800/sup 0/-1900/sup 0/F, the turbine has a gas-fired design rating of 40,000 hp for the simple cycle and 32,000 for the regenerative, with an overall thermal efficiency of 37.9% for regenerative units (equal to 6720 Btu/hp-hr) and 42.3% (6020 Btu/hp-hr) for a combined cycle. Variable-power turbine vanes produce an optimum power and efficiency of driven equipment over a speed range of 2500-5250 rpm. Spring-loaded blade and vane attachments allow onsite replacement with minimum disturbance to the equipment. Although much of the design is borrowed from existing technology, some original features include the interturbine vanes, variable-power turbine nozzle, and the variable inlet guide vanes.
