ConDex Condensing Economizer System. Currently 15 - 20 % of all fuel input energy is not utilized and lost as waste heat. Waste heat recovery represents one of the largest sources of green energy available for harvest. The ConDex Condensing Economizer System is designed to maximize recovery of both sensible and latent heat from exhaust gases.
The steam flow from a heat recovery boiler can usually be increased by the addition of an economizer to preheat the feedwater before it enters the evaporator. The impact of adding an economizer to the evaporator previously analyzed in Fig. 3.1 is shown in Fig. 3.2.The gas temperature leaving the system is reduced substantially and the steam flow is increased approximately 75%.
Maximize Boiler Heat Recovery with Condensing Economizers Presented to: ESC TMAF Birmingham, AL February 20, 2008 Presented by: Aqeel Zaidi, P.Eng, Enbridge Gas Distribution Inc., Toronto, Canada ph: 416-495-6531 email:firstname.lastname@example.org
It is estimated that between 20 to 50% of industrial energy input is lost as waste heat in the form of hot exhaust gases, cooling water, and heat lost from hot equipment surfaces and heated products. As the industrial sector continues efforts to improve its energy efficiency, recovering waste heat losses generate cost savings, reduces environmental impact, and improves work flow and productivity.
It is for this reason that it is it is essential to use compensation controls which will attempt to run the system, and in turn the return temperature to the boiler as low as possible below the dew point, not ‘just below it’, if you want to extract the maximum amount of latent heat. the further below dew point, the more condensing that will
The P-K STORM™ water-tube boiler is considered the greatest challenge to fire-tube technology by industry experts.It operates at up to 97% thermal efficiency with 10:1 mechanical turndown capabilities. Built to transform the commercial boiler market, this top of the line, highly efficient condensing boiler is designed to provide the highest levels of heating comfort while maximizing energy
This is the ratio of the boiler’s annual heat output compared to the total annual fossil fuel energy it consumes. An AFUE of 90% means that 90% of the fuel energy becomes heat for your home and the other 10% escapes either up the chimney or out through the boiler into the space where the boiler …
Aug 22, 2017· Exhaust condensate from a natural gas-fired condensing boiler typically has a pH ranging from 3.0 to 5.0, or mildly acidic. This acidity would be damaging to a cast iron or mild steel heat exchanger, so in a condensing boiler, heat exchangers are …
Leaky boiler heat exchangers leak water and are easy to spot. Furnace heat exchangers mix combustion gases with house air when they leak—an important safety reason to have them inspected. Adjust the controls on the boiler or furnace to provide optimum water and air temperature settings for both efficiency and comfort.
