The ultra-low nitrogen burner has perfectly solved the problem of excessive nitrogen emissions for us and made a huge contribution to protecting the environment. It is in line with my country's industrial policy and has good development prospects. Many people wonder what a burner controller looks like. Woolen cloth?
Combustion control instructions:
A single burner is equipped with SIMENS series program controller and flame monitoring system. This system mainly realizes automatic control through the programmable controller configured with the burner, and mainly includes the following parts:
(1) Valve group leak detection
Before each start-up operation of the burner, the program controller first sends a signal to the leak detector to perform a leak detection test on the valve group to ensure that the gas valve does not leak.
(2) Pre-purge
A successful purge of the furnace must be completed before fuel enters the furnace for combustion (either on initial ignition or after a boiler trip) to effectively eliminate any flammable gases that can accumulate in the furnace, otherwise the protection system prevents any fuel burner from starting. The entire purging process should be carried out under certain conditions. If any condition is lost during this period, the purging will be interrupted. Only after all permitting conditions are re-established can the operator restart the purging process.
(3) Ignition
Ignition is divided into two steps, first light the small fire, and then light the main fire. The ignition process is to ignite the main fire through 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 lights up, and waits for reset before restarting. If ignition fails, the burner will flameout and cut off all outputs. The flameout alarm indicator will light up and wait for reset before restarting.
(4) Flame detection
The burner flame detection system is used to detect the presence or absence of flame. When a fire is detected, a signal is sent to the program controller. The program controller automatically determines whether the flame signal matches the program according to the program. If it does not match, the program controller will alarm and cut off all outputs. (When a flame signal is detected during purging, the program controller will alarm; after ignition, the program controller cannot detect a flame signal, and the program controller will alarm.) The flame detector continuously detects the entire combustion process during the combustion process to provide safety protection. effect.
(5) Load adjustment
After completing the ignition procedure, the ultra-low nitrogen burner enters normal operation and sends an increase or decrease control signal through the load selector switch. The burner automatically adjusts the gas and air volume, changes the output, and achieves load regulation.
