Condensing Economizers from E-Tech
E-Tech's Condensing Economizers Yield Extremely High Efficiencies – Upward of 96%.
Condensing Economizers – The cost-efficient way to convert water vapor to recaptured heat.
During combustion of natural gas, water in the combustion air changes phase from liquid to gas. As a result, combustion products of natural gas typically contain 11% to 12% moisture, which represents up to 9% of beginning fuel content. With typical economizers, this energy escapes into the atmosphere with heated boiler gases. But a condensing economizer allows its recapture.
Using feedwater-cooled finned tubing, our condensing economizer cools exhaust gases below their dew point, releasing latent heat bound up in the vapor. The amount of recaptured heat is considerable — about 1,000 Btu per pound of condensate. The CO2 reduction is also significant: one cubic foot for each cubic foot of natural gas saved.
At E-Tech, we’ve been engineering precise custom solutions for our customers’ waste heat recovery needs since 1976, producing literally thousands of designs for virtually every type of application.
Whether you purchase a single component or a complete system, your E-Tech waste heat recovery equipment will meet your needs effectively and reliably for years to come.
