Steam Calculators: Boiler Calculator

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.

When to Replace a Steam Boiler – Three

2017-10-5 · Steam boiler inefficiencies can be a good reason to consider boiler replacement. Fuel cost is a major factor. The cost of inefficiency increases as operating hours and fuel costs go up. Even a slight improvement in efficiency may result in substantial savings. Another economic consideration comes into play when a steam boiler is in need of repair.

How Efficient Is Your Steam Distribution System?

Nobody measures their steam distribution system efficiency because there is no generally accepted method. So your system's efficiency is probably low -- not the 70-90% of the boiler, but instead the 30-60% of a neglected system. This paper proposes a method of measuring it.
