<p>A stove for burning solid waste material such as straw bales or wood shavings is fed automatically from a reservoir container through a pipe that leads into the bottom of the combustion chamber. The automatic feed may comprise a pusher sliding in the pipe under the action of ram or an auger. In either ease it largely blocks the pipe to prevent unwanted entry of air and is controlled by an element sensing flue temperature. The container outlet can include a ripping chain to break down the material and the pipe can include a fire extinguishing connection controlled by a heat sensor. The stove has provisions for admitting controlled quantities of primary air and the hot incompletely burnt gases of combustion pass to a after-burning chamber where secondary air is admitted.</p> |
