a portable air curtain incinerator for burning biomass , such as cleared logs and vegetation , is equipped with heat recovery panels along at least one of the sidewalls of the incinerator &# 39 ; s firebox , and a heat transfer medium is cycled through the heat recovery panels and expanded to its gaseous phase by heat released during incineration of the biomass . the gaseous medium is directed to drive the turbine of a generator to generate electricity . the heat transfer medium is condensed , preferably using a local source of cooling water , and the cycle is repeated . the air curtain incinerator may include its own generator , or multiple incinerators may be coupled to a single shared generator .
