Heavy oil is a by-product of crude oil after refining. It is generally prepared from cracked heavy oil, vacuum heavy oil, atmospheric heavy oil or wax oil in different proportions. Common heavy oil burners with different fuels include residual oil burners, waste oil burners, heavy diesel burners, as well as tar burners and asphalt oil burners, and Orly oil burners.
The calorific value of a heavy oil burner is an important economic indicator of fuel, and it is directly related to the fuel consumption of the asphalt station. The higher the calorific value, the better. Generally, the low calorific value of oil is 38.5～44MJ/kg.
Basic parameters of heavy oil burner：
1. Heavy oil burner.
2. Two-stage operation (high/low flame).
3. High pressure mechanical atomisation of fuel using nozzle.
4. Ability to obtain optimal combustion values by regulating combustion air and blast-pipe.
5. Maintenance facilitated by the fact that the atomisation unit can be removed without having to remove the burner from the boiler.
6. Minimum and maximum air flow regulation for first and second stage by means of electric servomotor with pause closure of gate to prevent any heat dispersion to flue.
7. With the fuel pre-heater which installed with thermometer and adjustable temperature controller.
8. One flange and one insulating seal for boiler fastening.
9. Combustion air intake with air flow adjustment device.
10. Adjustable blast-pipe with stainless steel nozzle and deflector disk in steel.
11. Three-phase electric motor to run fan and pump.
12. Flame presence check by photo resistance.
13. Electrical plant protection rating lp40.
