L.P&H.P Heater The low pressure and high pressure heater in steam power plant is used to increase the efficiency of boiler. The condensate water from the condenser get heated in L.P heater by steam which is extracted from L.P Turbines. The water after BFP get heated by H.P heater by steam which is extracted from H.P & I.P turbines.

The boiler is the part of a steam power plant process that produces the steam and thus provides the heat. The steam or hot water under pressure can then be used for transferring the heat to a process that consumes the heat in the steam and turns it into work.

High Pressure Boilers: Features and Advantages ~ M

A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

2019-9-2 · Because of these conditions, high-pressure boilers are prone to caustic attack. Low-pressure boilers that use demineralized water and condensate as feedwater are also susceptible to caustic attack. There are several means by which boiler water can become highly concentrated. One of the most common is iron oxide deposition on radiant wall tubes.
