Question
3- A reaction turbine is supplied with steam at (60 bar, 600 C°). The condenser pressure is (0.07
bar). If the reheat factor can be assumed to be (1.04) and the stage efficiency is constant
throughout at (80%). Calculate the steam flow required in (ton/hr) for a diagram power of
(25 MW). (Ans. 75.6 ton/hr)
4- The steam consumption at full load for a (3 MW) turbine is (16.6 ton/hr). At half load the
steam consumption is (9.1 ton/hr). Applying Willan's line, estimate the steam consumption
at no load, and the consumption at a load of (2.5 MW).
(Ans. 1.6 ton/hr; 14.1 ton/hr)
