Firstly, work, gas pressure test and temperature control signal are used to judge whether the burner is allowed or not. If the conditions are met, then start the fan motor, throttle open to the maximum, top blow and pressure detection, this period of time (through constant pressure, pressure detection) is not normal, it is normal, stop alarm; The door is close to the flame ignition position, igniter ignition, gas valve open gas, ignition, flame detection, such as flout, stop alarm is normal, according to the fire signal, decide whether to put into production two types of fire. The control system determines the gas pressure and temperature control signals during the burner operation. If it is out of range, the burner will stop. When conditions are met, the burner automatically restarts, starting with the connection of the control power supply. Before installation, check whether the chimney (sectional area and height) conforms to local standards and the requirements of the equipment manufacturer. The voltage and frequency of the power supply must meet the requirements of the burner. C. The gas system and dimensions shall meet the requirements of the specification, the gas regulating valve and accessories shall be tightened, and the gas tightness inspection shall be conducted. D. Check whether the burner accessories are complete. E, the pressure relief regulator is installed in the horizontal position of the filter. Clean the inner wall of pipe with rust and impurities.(2) a, install asbestos gasket between boiler installation plate hole and installation flange, then screw in the bolt, the burner head enters the desired position of the combustion chamber, bolt installation flange, the burner will be fixed. Boiler plates, asbestos gaskets and mounting flanges should be sealed without air leakage. In the process of burner operation, high temperature flue gas leakage, burner combustion. Connect the power cord according to the wiring diagram. (1) Be prepared to check whether all valves are open before starting. B. Open the boiler and chimney check valve to discharge combustion products smoothly. Valves should be replaced after the air line before the C and fuel burner lines. D. Check whether the wiring and the rotation direction of the motor are correct. If the rotation is in the opposite direction, it will be on the side of the two-phase power line. Ignition, throttle opening and throttle opening are set by throttle control servo motor. The length of the combustion head entering the combustion chamber meets the manufacturer's requirements. Whether G, thermostat and pressure switch are connected to the wiring diagram of the control box. H, the fire requires the position of the airflow. A suitable pressure range for measuring gas pressure.(2) when the main switch and temperature controller are turned off, when the power supply voltage reaches the motor, the fan motor is. The fan is used for blowing and blowing. The burner is equipped with an air door control servo motor, which is connected to the corresponding position of the two-stage fire door, and the air supply fan works to the combustion chamber before combustion. After cleaning, the door back to the fire position, ignition transformer start three seconds, fire valve and safety valve open at the same time. The burner is running. The flow regulator can be configured with fuel flow at startup. C. Flame and fire detectors detect fires and complete the ignition process.(if there is no fire, after the first valve is opened for 2 seconds, the device enters the safety lock, press the reset button to unlock the device, and then undergo purification.)D. After the completion of a fire setting operation, close the burner, connect two kinds of fire constant temperature circuits, open the main switch, start the burner, and prepare two kinds of fires. E. Close the main switch and switch device, ignite the burner, automatically enter the second stage flame state, then observe the flame shape, adjust the flow of fuel and air as needed. F, when the boiler or pressure temperature controller or pressure switch setting the second, the second level of temperature controller or pressure switch disconnect, the second level of fire stop operation, only the first stage of the flame in operation, if the temperature and pressure is still more than the set value, the temperature controller boiler burner shut down, stop running. On the other hand, if the secondary flame is stopped and the temperature and pressure of the boiler are lower than the set value, the secondary flame is reignited.
