Five control principles of oil-fired hot water / steam heater burners
The electrical control of the burner of the water heater is mainly to control the working procedures of each component, and this task is completed by the program controller. There are two types of program controllers: electronic and mechanical. The models and specifications of the program controllers used by various types of burners are quite different, but the general functions and principles are basically similar. Article 167 of the 96th edition of the "Steam Boiler Safety Technical Supervision Regulations" issued by the Ministry of Labor stipulates the ventilation time of the burner. At present, some program controllers cannot meet the requirements of the rules. Therefore, this aspect should be mentioned when ordering. request.
The electrical control of the burner of the oil-fired water heater mainly consists of the power supply circuit of the injection motor, the solenoid valve circuit, the ignition circuit, the photosensitive circuit and the servo motor circuit. Its working principle is divided into the following five aspects.
1. Throttle reset circuit. 2. Main motor circuit. 3. Ignition circuit. 4. Photosensitive circuit. 5. Solenoid valve and servo motor circuit.
