Thermal Energy International Unveils A Larger Range Of Flu-ace Systems At Maintec

Most natural gas or LP boilers and appliances are between 80 - 85% efficient, allowing 15 - 20% of the usable energy to escape up the chimney in the flue gases. By installing FLU-ACE equipment our customers have seen this upgraded to 90 - 95% efficiency and in addition dramatically reducing CO2 emissions. Large savings can also be made with CHP systems with the FLU-ACE providing even greater efficiencies of, in some cases, up to 100%.

FLU-ACE effectively converts an Industrial boiler into a condensing boiler, recovering waste heat to make hot water. During the boiler operation, water enters the top inlet of the economizer and is sprayed over the heat transfer media. Simultaneously, boiler flue gas is directed to the flue gas inlet, at the base of the economizer. Cold water, for example from the boiler feed water supply travels from the spray nozzle to counter-flow from the rising flue gas through the stainless steel transfer media. As the water droplets travel through the media, the hot flue gas rises to the top of the economizer directly contacting and preheating the water. Used either on its own or with an indirect economiser, water temperatures of up to 120’C can be achieved, whilst exhaust temperatures are reduced, often to around 25’C.

Conventional heat recovery technologies require dedicated equipment for each boiler exhaust. However a single FLU-ACE can handle a varying flow of flue gases emitted from multiple boiler exhausts. This results in a lower initial investment, cheaper operating costs and a higher potential return on investment. A full payback is often achieved in less than three years with continuing savings being maintained throughout the unit’s 20-year plus operating life.

The FLU-ACE unit’s internal structure ensures maximum condensing heat and mass transfer. It also enables an unobstructed flow of liquids and gases through the tower, providing continuous operation.

Thermal Energy International Inc will have a model of FLU-ACE displayed on their stand, which will enable visitors to Maintec to obtain a greater knowledge of the system and how it works.
