Mechanical Reliability Considerations in the Modern High Temperature Industrial Gas Turbine

Abstract

The mechanical design considerations of the CW352 two shaft industrial type gas turbine are discussed with emphasis on achieving a high degree of mechanical reliability based on the extensive service experience of the company’s mature 1450°F inlet machines. Problem areas of the early units are discussed and how avoidance of problems has been considered in the design of the CW352.

Modified Exhaust-Heated Gas Turbine Cycle With Increased Thermal Efficiency and its Prospect for Industrial Application

“…Combustion air demand ma = Xm as (12) so in this case ma 4.7084 x 16.6654 = = 78.4669 kg/kg of fuel. Unit demand for combustion air (ma )u = mab (13) from which (ma ) u = 78.4669* 0.01328.= 1.042 kg of combustion air per kg of working air, so accordingly the ratio f = b (14) (m5 )…”
