Title: Method of heating and generating infrared rays and apparatus thereof
Inventor: INAI KATSUYOSHI
IPC: F23C3/00
Filed: 1987-02-06
Abstract: PURPOSE:To miniaturize a body, to increase the thermal efficiency, and to enable use of liquid fuel except gas as fuel, by burning fuel in a combustion chamber which is cooled by a heat transfer medium, by feeding combustion gas into a radiator after its temperature is lowered down to a predetermined temperature, and by radiating infrared rays from the radiator. CONSTITUTION:Combustion gas in high temperature flows into a tubular radiating pipe of far infrared rays 10 from a combustion gas outlet 9, lowering its temperature by giving its heat to a water chamber 7 which surrounds a combustion chamber 5. The combustion rate, the heating area of a combustion chamber, and the flow rate of a heat transfer medium are determined so that the temperature in combustion gas at that time is to be below 800 deg.C and above 400 deg.C. The reason why the upper limit of temperature is 800 deg.C is that the maximum temperature in a radiating pipe 10 is nearly below 500 deg.C when the temperature in a heating chamber is supposed to be 100 deg.C and that a steel sheet is not red-heated. The wave length of infrared rays from the radiating pipe 10 is nearly within the zone of far infrared rays, and as a whole the pipe 10 radiates the rays in the zone of far infrared rays to the main. The reason why the lower limit of temperature is determined as 400 deg.C is that the temperature in exhaust gas at the final is nearly 200 deg.C at the lowest and that the generating rate of far infrared rays will be low when the temperature is too low. The rays from the radiating pipe 10 is radiated by radiating boards 13, 13, heating an object to be heated.
