Abstract
A combustion device has a negative pressure combustion burner and an ejector air flow generating mechanism and is designed so that the warm air flow rate is approximately proportional to the combustion rate. The device is simple in construction, and by controlling the warm air flow rate it is possible to adjust the heat output of the device while maintaining the temperature of warm air at a constant value. The device disclosed herein is particularly suitable for use as an air circulation type room heater.
