Steam Pressure Measurement In Boiler - hof-hicken.de

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.

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

2011-3-18 · Reference 1 acknowledges that compressed airblows have been as effective as steam-blows in cleaning steam lines and suggests the cleaning method should be selected based on particular circumstances. The major benefits of compressed air-blows are scheduling flexibility, extended boiler life by eliminating temperature cycles associated with saturated steam blows, and reduced cost.

Heat Recovery from Boiler Blowdown TDS Control

Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.
