A compact, unfired, staggered tube, once-through steam generator or boiler of simple construction intended primarily for combined cycle power plants in which the thermal energy utilized to generate steam is obtained from the exhaust gases of a gas turbine engine. The boiler provides steam at two different pressure levels, which maximizes recovery of thermal energy; and all wettable components in the steam/water loop are fabricated of corrosion resistant materials. This eliminates the need for controlling the pH of the feedwater and the need for chemicall...
A combined cycle power plant comprising: a gas turbine engine; a once-through boiler; means for effecting a flow of feedwater into said boiler; means for effecting a flow of exhaust gases from said gas turbine engine through said once-through boiler to convert said feedwater to steam; a steam turbine; and means for effecting a flow of the steam generated in said boiler to said steam turbine to drive the latter, said once-through boiler comprising: a vertical casing having a gas inlet and a gas outlet respectively located at the lower and upper ends there...
