Incinerators for aqueous wastes

To burn the oxidisable elements in the waste water, it must either be evaporated outside the combustion chamber, or it evaporates inside the combustion chamber. The high heat of evaporation of water, which normally has to be achieved by using primary energy, is synonymous with a high specific energy requirement. CALORIC developed a process that yields in a drastic reduction in fuel consumption while burning aqueous wastes. The water content of the waste is evaporated at temperatures below 100 °C. This allows to utilize not only the sensible heat but also the heat of condensation of the water vapour in the incinerator off-gas for the waste pre-concentration. Instead of a liquid injection the wastes enter the combustion chamber gaseous.

Besides fuel reduction up to 50 %, the plants are getting smaller and less expensive.
