He smiled. On to page 134.

Feasibility? “Not feasible,” he whispered. “You’d need an infinite heat exchanger surface area and a miracle.” Steam And Gas Turbine By R Yadav Pdf 133 HOT

Outside, the library lights glowed steadily. Somewhere, a gas turbine spun, a steam turbine turned, and a grid of millions stayed bright—because someone, years ago, had bothered to check feasibility. He smiled

He rechecked. The gas turbine alone was showing 32% efficiency. The steam bottoming cycle was pulling another 26% from waste heat. That meant the HRSG was impossibly perfect—zero losses, no pinch point violation. “Not feasible,” he whispered

But something had clicked. Not just the numbers—the thinking . Feasibility wasn’t an afterthought. It was the first question. Every cycle, every blade, every combustion chamber had to bow to reality: materials that melt, gases that won’t cool below a friend’s temperature, friction that laughs at theory.

He began, methodically. Gas turbine first: compressor work, combustion chamber heat addition, turbine expansion. Then exhaust gases—still scorching at 550°C—feeding the HRSG. Steam at 60 bar, 480°C, expanding through the steam turbine, then condensing, then back to the HRSG.

He had solved thirty-two problems on regenerative cycles, reheat factors, and nozzle efficiencies. But this one was different. It described a combined cycle plant: a gas turbine topping a steam turbine, with an intercooler, reheater, and a heat recovery steam generator. The data was messy—inlet temperatures, pressure ratios, isentropic efficiencies, pinch points. And at the bottom, a deceptively simple question: “Determine the net work output and thermal efficiency. Comment on the feasibility of the cycle.”
