Combined-cycle power plants (Fig. 2.3) are compound gas turbine–steam turbine systems wherein the extreme hot exhaust from a gas turbine is employed to run a boiler, and the steam thus produced is fed into a steam turbine to generate power.These plants can deliver high power output at efficiencies as high as 50%–60% with low emissions and produce 50% more electricity than a simple-cycle
Read MoreNov 08, 2019 · The water or freeze proof liquid (depending on application) is warmed by a boiler or water heater. The heat radiates from below warming a room or melting the snow if used in drive way. Rate of Flow – This is a term used to describe the volume of moving water as it related to a time period.
Read MoreIn a double boiler, melt chocolate chips and shortening, stirring occasionally, until smooth. Holding them by the toothpicks, dip the strawberries and marshmallows into the chocolate mixture. Turn the strawberries and marshmallows upside down and insert the toothpick into the Styrofoam while the chocolate cools and hardens.

(2) Every low pressure hot water boiler and every unfired boiler in use at a work place shall be inspected
Read MoreSteam is bled from the main turbine H.P. exhaust to drive the main boiler feed pump turbine, which exhausts to the feed heating system to improve the overall cycle efficiency. The main feed pump turbine is a 15,150 hp single-cylinder impulse machine with steam conditions, at the h.p. exhaust, of 610 psia (42.06 bar) at 366 °C.
