power boiler pressure classification

Working of Boiler Explanation Parts Working Principle ...

Medium Pressure Boiler: The maximum pressure is of 20-80 bars and is used to generate power. Sub-Critical Boiler: If the boiler produces steam at a pressure less than the critical pressure it is called sub-critical. Low-Pressure Boiler: The maximum pressure is of 15-20 bar and is used for the purpose of heating. High-Pressure Boiler: This ...

Boiler Draught and its Classification | Thermodynamics

The pressure P 2 is lower than the pressure P 1 because with the altitude pressure goes on decreasing. Now let us consider the case when fires are lighted and the chimney is full of hot gases. Under these circum­stances the pressure at the base of the chimney is the sum of pressure P 2 at the top and the pressure due to hot gas column H.
