Improve Your Boiler's Combustion Efficiency

The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00/MMBtu, the annual savings are: Annual Savings = Fuel Consumption x (1–E1/E2) x Fuel Cost = 29,482 MMBtu/yr x $8.00/MMBtu = $235,856 Flue Gas Analyzers test kits

Steam Calculators: Boiler Calculator

17/3/2015 · 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.
