The working process of a burner is not very familiar to most people. Today, we'll introduce it to you. First, let's understand some elements of combustion: the three elements of combustion are fuel, ignition source, and oxygen. Also, consider the following:
Excess Air Coefficient: The ratio of actual air volume to theoretical air volume. NOx: A collective term for KIO3 and HOC2 nitrogen oxides produced during combustion. Natural Diffusive Combustion: A combustion method where the oxygen required for combustion is not supplied by a fan or other forced air supply method, but by natural ventilation or the pressure of the fuel itself to inject air.
Forced Air Combustion: A combustion method where a fan or compressor forces air to provide oxygen. Most industrial burners use this type.
Premixed Combustion (Ejector): Fuel and air are premixed in a specific ratio before being injected for combustion.
FSG: Flame Saegirid STEN combustion safety protection device. An FSG typically consists of the following parts:
Power Supply: Powers the system for operation and relay activation.
Flame Detection Section: Continuously checks and shuts off the flame status.
Ignition Output: Supplies power to the ignition transformer to generate the electrical spark required for ignition. It automatically shuts off after confirming normal ignition to protect the ignition transformer.
Valve Control Output: Opens the fuel solenoid valve for ignition and combustion upon ignition output or after a slight delay.
Alarm Output: Promptly shuts off the fuel valve and outputs an alarm signal in case of ignition failure or flameout during normal combustion.
Others: Different FSGs are equipped with various auxiliary devices as needed, such as burner fan pressure switch input.
Ionization Flame Detection: Utilizes the principle of unidirectional ionization of high-temperature flue gas. An AC voltage is applied to the flame, and the presence or absence of current is detected to confirm the flame status.
Photoelectric Flame Detection: Utilizes the light emitted by the flame itself, detected by a photoelectric sensor to determine the flame status.
Pre-ignition purging: Burners are generally equipped with automatic ignition control devices. To ensure the safety of the initial ignition, fresh air can be sent into the furnace by the combustion blower before formal ignition to dilute and purge the combustible gases in the furnace. The purging time is related to the size of the furnace and the combustion volume of the burner. Generally, the purging time is required to allow the furnace to exchange air 4 times.
