This paper presents details of a heat-recovery boiler design as applied to gas turbine exhaust for the generation of steam. The factors involved in such applications are reviewed, together with an explanation of the heat-balance calculations and the limits that apply. A description is given of the parameters used in the design of the heat-transfer surface in the boiler. A specific design is described including details of the components in the boiler train. Reference is made to factors to be considered in erection and installation of this equipment. An explanation is included of the computer programs used to determine the optimum heat balance and for boiler selection and performance at “off-design” operating points. The operating performance of an actual installation is included.
