How to solve the problem of non ignition of gas steam generator

Due to the use of clean energy and combustible natural gas as fuel in gas steam generators, the first step to ensure normal heating is ignition of the gas steam generator. In the process of using a gas boiler, we may encounter situations where the gas steam generator fails to ignite. At this time, the first step is to identify the cause of the gas steam generator failure and take measures to solve the problem. Next, the steam expert from Novelty will introduce the common reasons and solutions for the failure of the gas steam generator to ignite

Reasons for ignition failure of gas steam generator

The reasons for the failure to ignite or ignite the gas steam generator are:

The insulation ceramic body of the ignition needle is damaged or the metal needle is loose, resulting in weak ignition spark; Abnormal power supply to the gas valve causes the solenoid valve to fail to open; The proportional valve ignition current regulation is unreasonable; Unreasonable regulation of small fire gas flow rate in segmented valves; Foreign objects accumulate in the gas valve, causing poor start-up; Poor rubber diaphragm of proportional valve; The solenoid valve coil is damaged (short circuit or open circuit); Gas pressure is too high or too low; Return the high and low speed lines of the dual speed fan; The parameters related to the ignition needle are incorrect.

The solutions for ignition failure of gas steam generator include:

Replace the ignition needle; Replace the main controller; Adjust the ignition current of the proportional valve reasonably; Adjust the reasonable flow rate of small flame gas through segmented valves; Remove foreign objects from the gas valve; Replace the gas valve; Replace the solenoid valve; Adjust the gas pressure to the rated pressure; Correctly connect the high and low speed lines of the dual speed fan; If the distance between the ignition needle is too large or too small, adjust it to 3-4mm. If the direction of the ignition needle is severely skewed, adjust or replace it. If the distance between the ignition needle and the burner is too far, adjust it reasonably.
