Heatsupply modification for  9F gassteam combined cycle units

Abstract

Abstract:

In order to further improve the energy utilization rate of the gassteam combined cycle units and meet a higher heating demand, the original heatsupply scheme for units need to be modified. Taking 9F gassteam combined cycle units in a power plant as an example, the actual operation of the unit after modification was briefly described. The advantages and disadvantages of three heating modification schemes were analyzed in detail. The parameters after modification were analyzed，and the results show that the modification has improved the performance of heat supply and ratio of heattoelectricity, and reduced gas consumption for power generation， which provides reference of the modification for units of the same type.
