Abstract:
A heat producing system for a building for utilizing decomposing vegetable matter to introduce heat into a heating duct system of a building comprising, in combination:a cylindrical housing having a closed upper end, a closed lower end, a cylindrical side wall therebetween, and a hollow interior, the cylindrical housing being constructed of fire bricks, the closed upper end having an opening therethrough exposing the hollow interior, the opening having a door removably positioned thereon, the cylindrical housing having access steps extending from the closed upper end to the closed lower end; a piping system disposed within the hollow interior of the cylindrical housing, the piping system including a series of air inlets extending outwardly of the cylindrical housing adjacent to the closed lower end thereof, the piping system including a single outlet pipe extending outwardly of the cylindrical housing adjacent to the closed upper end thereof, the single outlet pipe being coupled with a heating duct system of a building; and a quantity of vegetable matter positioned within the hollow interior of the cylindrical housing, the vegetable matter being positioned over the piping system whereby as the vegetable matter decomposes, heat will be generated thereby warming air within the piping system whereafter the warmed air will rise out through the single outlet pipe into the heating duct system of the building and drawing cooler air in through the air inlets for subsequent heating.
