Gas steam generator

  As a clean energy, it is favored by all walks of life. It uses natural gas as fuel. If the gas steam generator is to operate normally, the first thing to be done is the ignition of the gas steam generator. In the process of using gas boilers, we may encounter situations where the gas steam generator does not ignite. At this time, first find out the cause of the gas steam generator failure and take corrective measures for the failure.

  What should we do when the gas steam generator fails to ignite?

  1. Turn on the power, press start, the motor does not rotate

  Reasons for failure: (1) Insufficient air pressure and lock (2) The solenoid valve is not tight, and the joint is leaking. Check the lock (3) The thermal relay is open (4) At least one of the condition loops is not established (water level, pressure, temperature and whether the program controller is energized start)

  Elimination measures (1) Adjust the air pressure to the specified value (2) Clean or repair the solenoid valve pipe joints (3) Press reset to check whether the components are damaged and the motor current (4) Check whether the water level, pressure, and temperature exceed the limit

  2. After starting, the front blowing is normal, but it does not catch fire

  Failure reasons: (1) Insufficient electric fire gas volume (2) Solenoid valve does not work (main valve, ignition valve) (3) Solenoid valve burns out (4) Unstable air pressure (5) Too much air volume

  Elimination measures: (1) Check the line and repair it (2) Replace it with a new one (3) Adjust the air pressure to the specified value (4) Reduce the air distribution and reduce the opening of the air door

  3, the light does not ignite, the air pressure is normal, and the electricity does not ignite

  Fault reasons: (1) Ignition transformer burned out (2) High-voltage line damaged or dropped off (3) The gap is too large or too small, the relative size of the ignition rod position (4) The electrode is broken or short-circuited to the ground (5) The distance is inappropriate

  Elimination measures: (1) renew (2) reinstall or renew (3) re-adjust (4) reinstall or renew (5) re-adjust

  4, turn off after 5S after lighting

  Reasons for failure: ((1) Insufficient air pressure, too much pressure drop, low air flow rate (2) Too small air volume, insufficient combustion, thick smoke (3) Too much air volume, white gas

  Elimination measures: (1) Re-adjust the air pressure, clean the filter screen (2) Re-adjust (3) Re-adjust

  5. White smoke

  Failure reason: (1) The air volume is too small (2) The air humidity is too high (3) The exhaust temperature is low

  Elimination measures: (1) Reduce the air door (2) appropriately reduce the air volume and increase the inlet air temperature (3) take measures to increase the exhaust gas temperature

  6, the chimney drips

  Reasons for failure: (1) Low ambient temperature (2) More low-fire combustion processes (3) High hydrogen content in fuel gas, and large excess oxygen to produce water (4) Long chimney

  Elimination measures: (1) Reduce air distribution (2) Reduce chimney height (3) Increase furnace temperature
