PURPOSE: An air heater is to supply properly heated air into a vinyl covered green house to stimulate growth of vegetables or flowers in winter for the increase of yield. CONSTITUTION: The air heater includes an outer case cylinder(100) having a smokestack(120) installed on the top and connected with a smokepipe(121) for discharging waste gas generated by solid fuel combustion. On the top of the case(100), some air inlets(130) are provided to supply air for heating and each has an air suction fan(132) with a motor(131) facing downward to be housed in the housing(133) having props(134) on the upper to hold the motor(131), the fan(132) supplying air into the space(280) between the inner cylinder(200) and the outer one(100). A solid fuel feeder(150) with a hopper(140) is installed on the side part of the outer cylinder(100) to feed solid fuel into the burner through a screw conveyer(153) operated by a motor(151). |
