Oct 27, 2016· 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.

File Size: 258KB Sep 22, 2018· Steam first enters the high pressure (“HP”) rotor through the inlet control valve (s). HP steam flows through the high pressure rotor, and exits the last HP stage to return by way of a steam header to the reheat section of the boiler, where it is reheated (at constant pressure)

High Pressure Boiler | Water Tube Boiler High Pressure Boilers Working. Before converting to steam, water circulates multiple times from shell (water drum) to water tubes and then back to shell.During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes.

The advances in steam pressure and temperature led to the development of the reheat cycle, where steam is exhausted from the high-pressure turbine at reduced pressure and temperature and is then returned either to a section of the boiler or to a separate boiler to be reheated. Once reheated, the steam is sent to the low-pressure boiler.

The operating engineer in a high pressure boiler plant of over 500 horsepower may leave the boiler room for up to 30 minutes if all boilers are equipped with dual pressure controls and dual low water fuel cutouts, one of which must be the manual reset type.
