Evaporative cooling in biomass energy plants

A major challenge of biomass energy plants is fouling and corrosion of the gas cooler.
Dall Energy have a patent pending on a new method to cool and clean gases and recover the heat from the cooled gasses, which overcome the problems of fouling and corrosion.
The cooling technology is used within heavy industry: cement and steel, where it is necessary to cool and clean the gas before it is led to the stack. The cooling is done by injection of fine droplets of water into the hot gas. Due to the high evaporation energy of water, the gas is cooled efficiently to about 150-250°C.
By using the innovative air-moisturizing system the gases can be cooled to about 35 °C, and hereby can the energy efficiency of a plant be increased by 10-15 %.

A full scale demonstration project in Denmark is being prepared.
