COMPARISON OF DESIGN FEATURES AND PERFORMANCE TEST METHODS FOR COMBINED CYCLE HEAT RECOVERY BOILERS

Directing against the structural features of gas turbine's heat recovery boiler, the design characteristics of said boiler have been analysed, summarizing several methods for measuring and calculating the utilization coefficient of heat recovery boiler and the flow rate of inlet gas. Combined with the field practice, a counter balance method for heat recovery boiler has been put forward, coming to a conclusion of using different method according to different situation in the field.
