Combined cycle power plant
This patent describes a combined cycle power plant. It comprises: a gas turbine engine; a once-through boiler; means for effecting a flow of feedwater into the boiler; means for effecting a flow of exhaust gases from the gas turbine engine through the once-through boiler to convert the feedwater to steam; a steam turbine; and means for effecting a flow of the steam generated in the boiler to the steam turbine to drive the latter. The once-through boiler comprises: a vertical casing having a gas inlet and a gas outlet respectively located at the lower and upper ends thereof; an overhead support structure in the casing; independent steam generating circuits hung from the support structure, each of the circuits comprising a single, sinuous low pressure tube with horizontal tube runs and a high pressure tube of similar configuration internested with the low pressure tube. The horizontal tube runs being so staggered as to increase the transfer of heat from hot gases flowing upwardly through the casing to the high and low pressure tubes and the high pressure tubes each having feedwater, vaporizer, and superheater sections with the vaporizer and superheater sections being of greater diameter than the feedwater sections; and a feedwater pump for effecting a flow of water into the low and high pressure tubes at the inlet ends thereof.
