Plant Engineering | Steam Quality – Plant Operation

2011-5-11 · Steam quality is the proportion of saturated steam (vapor) in a saturated condensate (liquid)/steam (vapor) mixture. A steam quality of 0 indicates liquid (condensate), while a steam quality of 100 indicates steam. One (1) lb of steam with 95% steam and 5% percent of liquid entrainment has

Steam Calculators: Boiler Calculat

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.

Steam Pressure Reduction: Opportunities and Issues - NR

2013-9-26 · Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

Water Handbook - Preboiler & Industrial Boile

2019-9-3 · Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.
