Boiler - Wikipedia

Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

2015/3/17 · 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.

Water Handbook - Steam Purity | SUEZ

Steam purity should not be confused with steam quality. Steam quality is a measure of the amount of moisture in the steam. It is expressed as the weight of dry steam in a mixture of steam and water droplets. For example, steam of 99% quality contains 1% liquid water. Carryover is any solid, liquid, or vaporous contaminant that leaves a boiler
