ABSTRACT:
A fuel reactor particularly adopted for the efficient combustion of wood and wood-product fuels includes a core comprised of an inner fuel tube and an outer gas tube. Fuel is introduced into one end of the fuel tube and the combustion process is initiated. Perforations in the gas tube allow the combustion gas to progress down the fuel tube and combine with air in the gas tube. A high temperature is maintained on the gas tube to enhance the combustion process. In addition, high temperature-high pressure steam and air are introduced into the core to increase the reactivity rate of char products. The high temperature-high pressure steam is produced by a novel steam pump. The combustion gases are further processed through a gas dispersion chamber, including dispersion plates, and a gas expansion chamber. Heat is extracted from the combustion gases via a novel heat exchanger which includes a gas dispersion shelf, a radiating heat exchanger plate, a primary heat exchanger, and a condensing heat exchanger. A reheater chamber assures positive gas flow through the reactor and out a stack.
