AN INFRARED QUARTZ,LAMP HOT-AIR GENERATOR

Pagination or Media Count:
An infrared quartz-lamp hot-air generator was developed for heating inaccessible spaces, such as missile fuel cells and engine compartments, where other heater types may be impractical. The hot-air generator developed is not an ultimate in thermodynamic design, but rather a prototype for heaters of this type. Tests were conducted to determine the relationship between the temperature of the discharged air and time, and the relationship between conversion efficiencyAND ACTUAL FLOW RATE. The actual flow rate was controllable up to rates of 570 liters per minute. A maximum temperature of 870 F was reached by the effluent air flowing at 570 liters per minute at 45.41 kw input. At rated voltage 250 VAC of the quartz heaters, the maximum temperature rise rate was 6 F per second. However, an 80 increase in voltage increased the rise rate to 13.5 F per second. Author
