What are the components of the fuel system for boiler burners?
Does the operation of the boiler burner during use ensure the normal operation and output of the passage? Do we all understand the composition of the boiler burner fuel system? Let’s take a look together.
The fuel system of a fuel burner mainly includes oil pipes and fittings, oil pumps, solenoid valves, nozzles, and heavy oil preheaters.
Oil pipe and joint: used for transmitting fuel.
Oil pump: a mechanism that creates a certain pressure on the oil, with an output oil pressure generally above 10 bar (1 bar=1Kg/cm2) to meet the requirements of atomization and fuel injection. It is divided into single tube output and double tube output. Some burner oil pumps are coaxially connected to fan motors, while others have separate oil pump motor drives.
Electromagnetic valve: used to control the on-off of oil circuits, mostly consisting of two way valves and three way valves.
Nozzles: Their main function is to atomize oil droplets. The main parameters of the nozzle include injection angle (30 °, 45 °, 60 °, 80 °), injection method (solid, hollow, semi hollow), and injection quantity. Under the same pressure, nozzles with smaller fuel injection rates have better atomization effects.
Heavy oil preheater: Equipment for heavy oil burners, used to heat heavy oil to a certain temperature, reduce viscosity, and increase the atomization effect of heavy oil. Its temperature control device and burner control
