How to adjust the fire of the Riello burner

The way to adjust the intake air of the Riello burner is to adjust the pressure switch or install a throttle valve to control it. The following is a tutorial on how to adjust the flame of the Riello burner. ① Remove the overpressure switch and explosion-proof pin on the explosion-proof port, take out the medium temperature sensor, and take out the overtemperature switch. ②Set the vacuum target on the display to 25Kpa, and the vacuum switch to 20Kpa. ③ Put the flue gas cut-off valve on the chimney in the open state, and put the gas ball valve in the open state. ④ Exhaust the air through the release pipe on the gas pipe, and close the release valve until you smell the gas. ⑤ Install the portable pressure gauge on the pressure measuring point at the inlet end of the valve group. ⑥ Adjust the minimum gas pressure switch and air pressure switch to the minimum scale, turn on the burner and observe the gas butterfly valve (the gas butterfly valve should be rotated to 90° when the burner is pre-blowing on high fire, and the gas butterfly valve is generally at 25° when pre-blowing on low fire. °-30°). If not, the burner should be stopped first, and then realized by adjusting the servo motor. ⑦Turn the pressure adjustment screw on the valve group to the maximum opening, turn on the burner for the first ignition. It is possible that the ignition will be unsuccessful at the first two times, because the gas may be impure or the damper is too large, and the gas volume is small. ⑧ After the first ignition is successful, keep the burner burning at a low fire, and check the flow rate and adjust the flow rate (generally, the flow rate at low fire is about 1/3 of the gas consumption per hour of full load). After adjusting the flow rate of the low fire, switch to the high fire for combustion, and check and adjust the flow rate (the flow rate of the high fire is the full-load hourly air consumption of the unit) Adjust the size of the damper according to the measured value above (generally, the oxygen content of the flue gas after burning in a small fire is 5%, and the oxygen content of the flue gas after burning in a large fire is about 3%), and adjust the damper to the ideal position. ⑩ During the commissioning process, the change of the gas pressure gauge should be observed at any time. If the pressure does not meet the requirements or the fluctuation is too large, the unit may not be able to burn normally.www.burners-china.com
