The pinch point is that place in the heat exchanger where the temperature difference between the brine and the working fluid is the smallest; the value of that difference is the pinch point temperature difference, Δ T pp, and is shown in the figure at the interface between the preheater and the evaporator. The pinch point usually occurs there, but it is theoretically possible for it to …

Jul 13, 2009 · Unlike the power plant boilers, there are no air or gas handling fans. The flow of gases is due to the exhaust gas pressure from the Gas turbine. Pressure drops in the gas path of a HRSG is at a minimum to avoid higher exhaust gas pressure, which will affect the performance of the GT. This also eliminates the need of air preheaters.
