 The Reverberatory Incinerator was an Australian patent which achieved a much higher efficiency than its imported competitors by preheating and partly drying the refuse while it moved down a sloping, vibrating grate in the combustion chamber which itself was designed to reflect (reverberate) heat on to the incoming refuse.The function of the building dictates the location on a slope or embankment as it is an in-line, vertical "top gravity feed" process.The gravitation of the raw refuse from storage hoppers down to the combustion chamber, the ash pit, and the ash delivery hoppers required truck access on at least two levels, presenting problems of siting and the design of site works, at which Griffin was most adept.
