As steam condenses, it gives up its latent heat and the liquid condensate retains the sensible heat. Industrial processes that use steam in heating systems must also capture the condensate to maintain a high efficiency. Therefore, the amount of condensate produced per amount of steam is a useful metric in designing and evaluating heating systems.

2020-3-14 · For steam-using plants and facilities, calculating steam costs, like calculating steam pipe heat loss, is an important step towards revealing energy and cost savings opportunities. Loaded vs. Unloaded Cost of Steam. The cost of steam production throughout the course of various projects is twofold: loaded and unloaded cost.
How can I calculate the mass of steam formed at 373 K at 1 bar in a closed vessel? The container carrying a water at 303 K is heated by 1 kW heater. After that, the temperature reaches to 373 K.
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
The qualification indicates that the amount of steam produced is at a pressure of 0 psig and 212°F and feedwater at 0 psig and 212°F. Gross Steaming Rate: The amount of steam produced by a boiler at the outlet flange of the boiler. This includes the amount of steam produced to heat the water in the feedwater receiver (deaerator or hotwell).
