Steam Pressure Reduction: Opportunities and Issues
They are often oversized for summer operation and the peak load period. The operator of the plant must judge whether a boiler plant is oversized. 3. Before the steam plant owner attempts to reduce steam pressure, an assessment of the boiler plant and steam system should be made. This should include an analysis of the average and peak steam loads in

Mean steam consumption. The mean steam consumption of a flow type application like a process heat exchanger or heating calorifier can be determined from Equation 2.6.6, as shown in Equation 2.6.7. But as the mean heat transfer is, itself, calculated from the mass flow, the specific heat, and the temperature rise, it is easier to use Equation 2.6.7.

Boiler Capacities - Engineering ToolBox
Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)
