Infrared heater radiating power controlling method, involves switching on and switching off burner in periodic cycles of variable periods based on temperature on outer side of radiating body and default temperature value

摘要

The method involves feeding gas heated by a burner (6) to an end of a radiating body e.g. radiating pipe (2), where the burner is operated with a constant power. Temperature of an outer side of the radiating body is determined by a sensor (16). The burner is switched on and switched off in periodic cycles of variable periods based on the temperature on the outer side of the radiating body and a default temperature value. An independent claim is also included for a device for performing a method for controlling radiating power of an infrared heater.
