Read MoreMar 17, 2015 · 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.

Read MoreA boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

In this case, the P and M values are used to determine the percent P alkalinity of the total (M) alkalinity. For example, when P = 20 and M = 100, 20 divided by 100 yields 20% P alkalinity. P as % of M alkalinity. pH (approx) 0.
