Analysis of the reasons for the difficulty of ignition of biomass boilers

2020-01-09

The reason why the biomass boiler is difficult to ignite is that it cannot establish a stable small fire signal, which is caused by the abnormal detection of the small fire detector. The small fire detector is an ionized fire detector, which requires a contact area with the flame, the flame size is stable, and the gas pressure must be controlled within a strict range.

If the ignition gas pressure is too high, the flame of the small fire will move forward too long, leaving the detection range of the small fire inspection probe, it will cause the system to mistakenly believe that there is no small fire; if the gas pressure is too small, the incoming ignition gas will be too small However, the air blowing in the biomass boiler is large, and it is easy to blow out the flame, so it cannot be ignited.
