2012-9-25 · The high pressure, high temperature steam leaving the boiler expands in the turbine to produce shaft work. The steam leaving the turbine condenses into water in the condenser, rejecting heat and then water is pumped back to the boiler. Consider 1kg of saturated steam at pressure p. 1 and absolute temperature T 1, as represented by point 1. The

Boiler Water Level Control System Example |

An important variable to measure and control in a continuous boiler is the level of water in the "steam drum" (the upper vessel in a water-tube boiler). In order to safely and efficiently produce a continuous flow of steam, we must ensure the steam drum never runs too low on water, or too high.

Boiler Mountings - Functions, Parts, Diagram, Working

When the steam pressure in the boiler is more than the working pressure: The upward force exerted by boiler steam on the valve is overpowered by the downward force of spring. Under this condition, the valve automatically opens and the steam escapes to the atmosphere(Fig. (b)) until the pressure falls back to the working pressure.
