ComparisonElectric vs Gas Steam Boilers: Cost, Size and EmissionsElectric vs gas steam boilers: cost per 1,000 lb of steam with a worked example, efficiency, CO2, resistance vs electrode sizes and electrical service.
CalculatorBoiler horsepower calculatorConvert boiler horsepower to steam output (lb/h and kg/h), kW and Btu/h, or work back from steam demand to the boiler size you need.
CalculatorBoiler blowdown calculatorCalculate the continuous blowdown rate a steam boiler needs from feedwater and boiler-water TDS, the cycles of concentration, and the heat and water lost.
CalculatorCombustion efficiency calculatorEstimate boiler combustion efficiency, stack loss and excess air from flue-gas O2 and stack temperature with the Siegert formula, for gas, oil or propane.
