High Pressure Boilers: Meaning, Types, Characteristics .

Meaning of High Pressure Boilers: These are used to increase the efficiency of the plant. These are developed because of rising cost of fuel and restrictions on air pollution. Modern power generation plants generally use high pressure boilers. These high pressure boilers have pressures above 140 bar and the temperature may be up to 540 – 610°C.

an equivalent round hole, 1/4 inch in diameter. Lowering the boiler pressure reduces the leakage rate in the high pressure part of the system only. In order to estimate the leakage through this hole and the savings from lowering the boiler pressure, the following formula is used: Steam flow through a sharp-edged orifice: W = 24.24 x. Pa x D. 2

One consideration is the introduction of feedwater to the boiler. The pump used to charge the boiler must be able to overcome the boiler's operating pressure, else water will not flow. As a superheated boiler is usually operated at high pressure, the corresponding feedwater pressure must be even higher, demanding a more robust pump design.
