Steam Calculators: Boiler Calculator

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.

How Boilers Keep the Plants and Refineries Running Smoothly

Oct 28, 2013· Water Tube Boilers In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.
