Understanding Different Types of Waste Heat Recovery
There are two pores and skin flue gas waste heat recovery systems on current market today, those that recover the sensible heat and the great that recover the sensible as well as the latent heat. For those interested in pursuing the benefits of condensing economizer waste heat recovery, having know-how about these two different technologies and the full selection of their benefits is vital if you hope acquire maximum profits and profit the planet while doing so.
Flue gas sensible heat recovery systems, such as coil loop recovery systems, can normally create energy savings of 2 to 4% where as flue gas heat recovery systems that can recover the sensible and latent heat, such as condensing economizers, generate energy savings of 10 to 20%. Sensible and latent waste head recovery condensing economizer's allow businesses and organizations operating natural gas or LPG boilers or appliances to significantly reduce Carbon Dioxide emissions, reduce energy usage, conserve water, and spend.
There surely few numerous kinds of latent and sensible heat recovery systems as well; indirect and direct. Direct heat recovery systems spray water directly into the flue gas stream. The downside to this form of heat recovery often that the impurities in the exhaust gases contaminate drinking water. Direct heat recovery also does require another heat exchanger that can transfer the recovered energy into the stream water that requires heating.
Indirect flue gas heat recovery regarding the other hand, transfers the waste energy into drinking water that is important to be heated. You can actually avoid the indirect method of heat recovery, the actual being heated can obtain much higher temperatures than is possible using the direct contact method which explains able to become used without significant water treatment.
Many heat recovery systems use electric fans to push the exhausted flue gases from the boilers and through the condensing economizer. The conclusion result may be the same once it heats up comes for the amount of recovered heat, but some designs are different in that almost all of cases no additional electricity or fan will be needed to help the flue gases from the boiler to your condensing economizer. This is achieved through low flue gas resistant design. As these hot flue gases rise up through the recovery block and all through the aluminum fins, the waste energy staying transferred into the water that's the passing the actual stainless steel tubes. Since this exhaust gas is being cooled, its actually developing a vacuum and naturally assisting the flue gas flow.
As these exhaust gases rise thus cooled beneath the dew point temperature, condensation is being created. This condensation will likely drop down across pretty much all the aluminum fins your market recovery block, creating a self cleaning action. This created water is then collected and drained from the base section to where it may possibly then be treated (if needed) and utilized within a number of different ways.
The US Department of your energy states that for every million BTU's recovered accessible waste exhaust gases just to utilized into the building or facility, 118 lbs of CO2 are certainly not put in the atmosphere. For companies that are striving to find techniques to reduce their carbon footprint, you might greenhouse gases that can be reduced from a single appliance when applying this technology, seems to leave all the other methods significantly behind.
Condensing economizer waste heat recovery units are a profitable investment for all owners of natural gas and LPG boilers and appliances. Not only can the condensing economizer yield significant deals but additionally, you will become a bit more marketable business through better environmental stewardship in the type of reduced energy usage and less CO2 pollution levels.
