  • Boiler Economizer Types And Efficiency Calculation--ZBG

    Boiler economizer calculation A generally accepted "rule of thumb" is that about 5% of boiler input capacity can be recovered with a properly sized economizer. A higher percentage can be recovered with a Flue Gas Condenser, assuming there is enough cold water to condense all of the flue gas that is available.Learn More

  • Understanding Fuel Savings In the Boiler Room

    A typical economizer can increase boiler efficiency by 4% to 6%. Using an air heater to raise the com-bustion air temperature is commonplace with utility boilers but is almost never done with packaged boilers. The nec-essary ductwork is expensive and can x Learn More
