General information

The high heat content of exhaust gases, which is produced during combustion of damp biomass, often goes unused as a loss into the environment.

If it is possible, through a properly designed heat recovery system, to cool down the flue gas under the flue gas dew point it can be achieved a considerable increase in effectiveness. The lower the residual oxygen content and the higher the fuel water content, the higher the achievable effectiveness.

A flue gas condensation with an integrated depluming system enables, that the steam plume that exits the exhaust stack is not visible also below 0 degrees.

HEGER ENERGY BOOSTER

With our latest development the innovative "HEGER ENERGY BOOSTER" we enable our customers to save energy and costs for fuel.

The Heger Energy Booster is a heat recovery system, which can be retrofitted by smaller biomass boilers to increase energy efficiency.

Exhaust gases normally escape the boiler unused, but the Energy Booster use these exhaust gases for heating the heating water.

Consequently, we obtain a significant heat recovery effect and save fuel, which can be translated into cash. The performance of the exhaust gas heat exchanger is approx 10% of the boiler output.
