The ignition gun and oil gun combined thruster is one of the executive mechanisms of the boiler ignition program control system. The combined thruster can send the ignition gun and oil gun into or out of the furnace at a certain speed under the command of the control system. It has the advantages of superior performance, reasonable structure, flexible and reliable operation, and easy to achieve automatic control. The combined propulsion device has now formed a series, which can be divided into two types according to the driving mode: electric and pneumatic.

Picture of combined pneumatic thruster:

The combined pneumatic propulsion actuator consists of oil gun cylinder, ignition gun cylinder, electromagnetic valve, micro limit switch, conduit, bracket, junction box, and other components. The oil gun cylinder and the ignition gun cylinder are fixed on the conduit through a bracket, and the cylinder piston rod drives the oil gun and the ignition gun forward and backward respectively through a connecting plate; The oil gun cylinder uses a dual control solenoid valve to control the advance and retreat of the piston rod, and the ignition gun cylinder uses a single control solenoid valve to control the advance and retreat of the piston rod. The solenoid valves are high-performance and high-quality products; Respectively limit switches at the limit positions of advance and retreat to feedback the advance and retreat status of the oil gun and the ignition gun. The limit switch is an imported high-quality product, with a reasonable actuator structure design and reliable performance.
