ABSTRACT:
A high capacity snow melting apparatus has a hopper with one or a plurality of dedicated heater/blower units coupled to a plurality of commingled heat radiant conduits for contact with snow, ice and water, and manifolds connected to the conduits for additional heat exchange and to direct heated air onto snow in the hopper. Terminal sections of the conduits are elevated to an upper region of the hopper and have downwardly directed exhaust ports for substantial and efficient preheating of new snow loads. Heat exchanger passages through the heated air conduits allow water to flow in the path of heated air in the conduits to substantially increase snow and ice melting efficiency of the conduits. A water bath in the bottom of the hopper is level controlled to cover the conduits and drain water from the hopper.
