Product Introduction:

1、 Before selecting heavy oil burners, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. first popularizes the basic knowledge of fuel burners: classification and characteristics of fuel burners:

The fuel burner is abbreviated as a nozzle. The fuel oil needs to be atomized before combustion, so the nozzle should not only have the basic performance of a general combustion device, but also have good atomization ability to ensure complete combustion of the fuel. Fuel burners are mainly classified according to the atomization method of oil:

1. The gas medium atomization nozzle relies on the momentum of the gas medium to atomize oil, divided into high-pressure medium (steam or compressed air) atomization and low-pressure air atomization.

2. Mechanical atomization nozzle directly atomizes oil using mechanical methods, which means high-pressure oil is centrifugally crushed and suddenly expanded through the nozzle, or the oil is centrifugally crushed using a high-speed rotating cup and further atomized using low-pressure air.

In addition, methods such as ultrasound or magnetization are also used to reduce oil viscosity and improve the atomization effect of the oil; There are also methods to improve the atomization effect of heavy oil by using both medium atomization and mechanical atomization.

1. The low-pressure nozzle uses all combustion supporting air as the atomizing medium, relying on the momentum of the air flow to atomize the oil. The high oil pressure accelerates the oil speed, making it difficult to ensure atomization quality and poor combustion effect.

2. The atomizing agent for high-pressure nozzles usually uses high-pressure steam or compressed air, and the high-speed airflow formed by the atomizing agent impacts the fuel to atomize the oil.

The high-pressure nozzle has good atomization performance and strong adaptability to oil. The disadvantage is high noise and high usage cost. Suitable for various industrial furnaces with high heat loads.

High pressure nozzles are mainly divided into two types: 1. Externally mixed nozzles: Atomizers and oil are mixed outside the nozzle. 2. Internal mixing nozzle: The atomizer and oil are mixed inside the nozzle, and the atomization quality is good, such as the internal mixing nozzle with a diffuser and multiple spray holes.

2、 Heavy oil burners are mainly used in industrial furnaces and kilns in African countries or regions: heavy oil aluminum furnaces, heavy oil forging heating furnaces, heavy oil steel rolling heating furnaces, heavy oil heat treatment furnaces, heavy oil rotary kiln burners, heavy oil dryer fluidized bed furnace burners, heavy oil red brick kilns, heavy oil baking equipment, heavy oil waste gas incinerator burners, and other heavy oil kilns.
