Brief description of boiler safety performance
Safety protection measures for combustion systems
1. Abnormal flameout alarm shutdown measures: If the boiler fails to burn normally due to various reasons and failures, the controller will send a signal to each relevant system - the burner will be turned off, the alarm system will emit a strong sound, light alarm and give a fault. Type text hints. The boiler cannot be started again unless the fault is given an exclusion and a manual reset is made.
2. Operation power-off protection measures: If the system is shut down due to sudden power failure, the burner will automatically switch to the self-locking state, thus avoiding the unpredictable hazard caused by the automatic start of the burner when no one is calling.
3. Furnace purge measures: If the flammable gas in the furnace exceeds the standard, it is very likely that an explosion accident will occur when the burner is ignited. The two pre-furnace purge and post-purge procedures allow for a venting purge before and after ignition to ensure that the combustible gas content in the furnace is reduced to a safe range.
4. Flame sensor failure detection measures: During the operation of the boiler, the control of the combustion system by the controller is largely based on the detection of the flame parameters in the furnace, and the flame sensor is an important component for the completion of the detection. Therefore, the sensor is always tested before the burner is started to ensure proper acquisition of the parameters.
5. Safe ignition detection measures: If the burner fails to ignite and the system continues to operate, an explosion will occur. This measure ensures that the ignition fails and delivers a signal to the control system to control the shutdown.
6. Burner limit measures: In daily operation, if the burner head is opened due to maintenance and repair, the limit device will take effect immediately, causing the burner to be in a de-energized state to avoid accidental operation caused by the operator. Cause property damage and personal injury.
7. Pressure fluctuation protection measures: fluctuations in gas pressure not only cause a decrease in combustion effect, but may also cause irreparable damage to the burner. Therefore, when the pressure of the gas network fluctuates due to the gas supply side, the burner will automatically be transferred to the protection state.
8. Over-temperature and circulating pump suddenly stop protection measures: When the outlet water temperature is higher than the set working temperature, and the circulation pump suddenly stops working, the burner will be turned off and the alarm system will emit a strong sound and light alarm.
