Our ZXOQM series fuel oil burner uses clean fuel. As long as the liquid fuel can be used, safe and trouble-free.

The installation, commissioning, operation and maintenance of the burner must be carried out by qualified technicians approved by the relevant local production safety inspection department. All work must be in accordance with relevant local standards and specifications.

Installation and maintenance must be carried out in the case of power failure and cut off the fuel supply burner into operation before you must carefully check the power supply, fuel safety status and the correctness of the connection. Any abnormalities found must be shut down for maintenance.

Our fuel oil burners can be widely used in boilers, painting ovens, hot water furnaces, incinerators, heaters, heat treatment furnaces, die-casting machines, aluminum processing equipment, food processing and other industries.

Our Burners in the pursuit of high quality at the same time, and continue to improve the service system, and strive to provide users with a full range of services and technical support.

Our ZXOQM series oil burner mainly consists of oil system, air supply system, gas system and electric power control system. The overall structure of the burner is shown in the right figure.

Fuel by the motor driven gear pump will be fuel oil transmission, through the solenoid valve control into the air cylinder through the injector nozzle and air mixing to form an atomized and fan to send the combustion air mixed with the automatic ignition combustion.

Flame detector (electronic eye) will be based on the presence or absence of combustion flame output signal to the PLC control template to determine the flame burning and extinguished. If the flame is not lit or ignited accidentally extinguished, the program will not monitor the electronic eye flow signal, that is, to determine the flame is extinguished, will immediately issue instructions to stop the fuel supply and shut down.

ZX0QM series fuel gas burners are mainly composed of three parts: air supply system, gas path system and power control system.

When the combustible gas is controlled by the control system to enter the combustion head of the burner, the primary air is mixed with the combustible gas, ignited and burned, and the secondary air assists combustion to achieve full combustion. The combustion status is detected and controlled by the flame automatic tracking system. When there is a combustion failure (lack of oxygen in the combustion chamber, combustible gas under-pressure, combustible gas flow cutoff, insufficient gas volume, etc.), the control system issues an instruction and the solenoid valve of the gas supply system is quickly closed. , cut off the gas power supply, the burner automatically purges and then shuts down, indicating a fault.

The flame detector (ion electrode) will send a signal to the controller according to whether there is an ion current signal in the combustion flame to determine whether the flame is burning or extinguishing. If the flame is not ignited or is accidentally extinguished after ignition, the controller will not be able to detect the ion current signal, that is, it will judge that the flame is extinguished, and will immediately issue a command to stop the fuel supply and shut down the machine.

ZX0QM series burners adopt mechatronics design, integrating gas supply, combustion, flame monitoring, PLC program control, etc. with the combustion fan to achieve fully automatic safety control.
