The combustion controller can be automatically controlled by the programmable controller configured with the burner. In order to solve the trouble of remote monitoring and control, I will introduce it to you now.
Single burner is equipped with SIMENS series program controller and flame monitoring system. This system mainly realizes automatic control through the program controller configured with the riello burner, which mainly includes the following parts:
1. Valve group leak detection
Before each start-up of the burner, the program controller first sends a signal to the leak detector to perform a leak test on the valve group to ensure that the gas valve does not leak.
2. Pre-purge
Before the fuel enters the furnace for combustion (initial ignition or after the boiler trips), the furnace must be successfully purged to effectively clean any combustible gas that can accumulate in the furnace, otherwise the protection system prevents any fuel burner from starting.
The entire purge process should be carried out under certain conditions. If any condition is lost during this period, the purge will be interrupted. The operator can restart the purge program only after the permission conditions are re-established.
3. Ignition
The ignition of the combustion controller is divided into two steps, first a small fire and then a main fire.
The ignition process is to ignite the main fire with a small fire. After the flame is ignited, the flame detection device must detect the flame, otherwise the ignition fails, the program controller alarms, the flameout indicator light is on, and waits for reset and restart. If the ignition fails, the burner will be extinguished and the output will be cut off. The flameout alarm indicator light is on, and waits for reset and restart.
4. Flame detection
The burner flame detection system is used to detect the presence or absence of flame. When the presence of fire is detected, the signal is sent to the program controller. The program controller automatically determines whether the flame signal is consistent with the program according to the program. If it is not consistent, the program controller alarms and cuts off the output. (When the flame signal is detected during purging, the program controller alarms; after ignition, the program controller cannot detect the flame signal, and the program controller alarms) The flame detector continuously detects the entire combustion process during the combustion process, which plays a safety protection role.
5. Load regulation
After completing the ignition program, the ultra-low nitrogen burner enters the normal operating state, and the increase or decrease control signal is sent through the load selection switch. The burner automatically adjusts the gas and air volume, changes the output size, and realizes load regulation.
