Steam Cycle - an overview | ScienceDirect Topics. 2.3 Boiler and steam cycle model In the steam cycle shown in Figure 1, the pressure of the feed water increases to 2 atm by Pump 1. The feed water entering the deaerator is further preheated to 127 °C by the steam at 159 °C and 6 atm coming from the turbine extraction valve. Get a Quote

Rankine Cycle - Steam Turbine Cycle

1  · Rankine Cycle – Steam Turbine Cycle. In 1859, a Scottish engineer, William John Macquorn Rankine advanced the study of heat engines by publishing the "Manual of the Steam Engine and Other Prime Movers".Rankine developed a complete theory of the steam engine and indeed of all heat engines. Together with Rudolf Clausius and William Thomson (Lord Kelvin), he was a contributor to the

basic cycle of steam boiler - lestagioni.de

Nov 19, 2013· The amount of steam flowing from the boiler and the amount of water pumped back to the boiler must be equal. Since the steam cycle is a closed loop system, losses due to leaks, blowdown, and blow-offs due to excess pressures, have to be replaced to maintain a desired water level in the boiler's steam drum.

Boiler and Condenser Pressures - Rankine Cycle

1  · Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to the
