Mar 17, 2015· (Saturated Liquid) 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.

A 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.

Another important feature — specific to combi boilers — is the water flow rate through your taps. Essentially this determines how much hot water your boiler can send to your taps or showers. This is usually measured in litres per minute (l/min) and equates to the volume of water coming from your plumbing fixtures.
