ABSTRACT:
Apparatus for progressively burning biomass material comprising a retort defining a chamber, a linearly moving grate bed enclosed within the chamber with a space below and a space above for respectively supplying primary air to the lower side of the grate and for collecting gases generated by progressive distillation of the biomass material at the upper side of the grate. Primary air is supplied to the underside of the grate bed at different pressures lengthwise of the grate by a distribution chamber extending lengthwise of the grate of V-shaped cross section containing at its bottom a Venturi opening through which air is delivered to the distribution chamber from successive longitudinally-arranged plenum chambers which, in turn, are supplied with air through conductors connected to a primary air source, each of which contains a damper. The grate may be horizontal or inclined.
