ABSTRACT:
A heater for warming crops such as groves of fruit trees or vineyards or other crops susceptible to freeze and frost damage, includes a burner housing having inclined side walls for directing radiant heat generally outwardly toward the crops and a burner having fuel and air outlet orifices arranged to produce efficient and substantially pollution free combustion of fuel within the housing. A vapor generator may also be supported on the housing to reflect heat toward the crops, and water in the vapor generator is heated to produce a vapor barrier or blanket of fog which provides a thermal inversion layer to aid in maintaining the heat near the ground.
