Abstract

Agricultural forced air heaters marketed for use in farm buildings which house poultry, swine, and livestock are quite susceptible to the accumulation of dust and other particles. These heaters are gas fired units having combustion, air mixing, blower and blower motor components assembled in a parallelepiped housing. To admit incoming air for their blowers and burners the heaters have multiple openings in the form of grid-like air intake ports on various heater sides. In the environments in which they are used the extensive use of air intake holes is a disadvantage. In the heater herein panels form four distinct chambers, a blower chamber, an air mixing chamber, a motor chamber, and a combustion chamber. Air inlets open into the motor chamber as the only air inlets in the heater housing. These air inlets provide all of the air for the heater. The airflow within the heater thus is unidirectional, flowing, when the blower is operating, from the motor chamber into both the mixing chamber and the combustion chamber, and then into the blower chamber.
