摘要： Apparatus for controlling the operation of a biomass stove utilizes three proportional integral derivative (PID) controllers as part of a closed loop to control the fuel feed rate, the convection fan speed and the combustion fan speed. The first loop controls room temperature, the second loop controls the convection fan speed and the third loop controls the combustion fan. Appropriate temperature readings are utilized for the first and second loop. The third loop, which utilized feedback of the ratio between the heat exchanger temperature to the exhaust temperature, in addition to measuring these temperatures also references a library of look-up tables of such ratios over the entire heat range of the stove that have been correlated to combustion efficiency, as an input. This enables the operator to optimize the heat output for any operating point.

摘要： A heating apparatus for the combustion of highly variable biofuel feed stocks is generally provided. The apparatus generally includes a combustion chamber or burn box adapted to receive a regulated feed of biomass. The burn box includes a grate for receipt of a distributed mass of the regulated feed, and further includes an oscillating blade adjacent to the grate for agitation of the distributed mass of the regulated feed received thereby. The combustion apparatus for the production of thermal energy from a biofuel of the subject invention is preferably and further characterized by means for producing the distributed mass of the regulated feed of biofuel, and/or a burn box incorporating an oxygen manifold assembly adjacent to the grate.
