The English name of the burner is burner. Burners can be divided into many types according to different fuels, combustion methods, matching, etc. In a broad sense, the range of burners is even larger. For example, gas stoves and even lighters used at home are all burners. kind of. Basics of the burner
The definition is a kind of equipment that converts substances into heat energy through the chemical reaction of combustion—that is, air and fuel are mixed in an appropriate proportion through a premixing device to make them fully combustible. We usually distinguish by fuel, which is roughly divided into: pulverized coal burner, oil burner, gas burner, and biomass pellet burner.
Burner structure
The industrial burner system is relatively more complicated and can be roughly divided into: air supply system, ignition system, detection system, fuel system, and electronic control system. It will be more complicated when it comes to special equipment.
The function of the air supply system is to send air with a certain wind speed and volume into the combustion chamber. Its main components are: housing, fan motor, fan impeller, air gun fire tube, damper controller, damper baffle, cam adjustment mechanism, Diffuser disc.
The function of the ignition system is to ignite the mixture of air and fuel. Its main components are: ignition transformer, ignition electrode, and electric fire high-voltage cable. Flame length, cone angle and shape can be designed according to user requirements.
The function of the monitoring system is to ensure the safe and stable operation of the burner. Its main components include flame monitors, pressure monitors, temperature monitors, etc.
The function of the fuel system is to ensure that the burner burns the required fuel. The fuel system of the oil burner mainly includes: oil pipes and joints, oil pumps, solenoid valves, nozzles, and heavy oil preheaters. Gas burners mainly include filters, pressure regulators, solenoid valves, ignition solenoid valves, and fuel butterfly valves.
The electronic control system is the command center and contact center of the above systems. The main control element is the program controller, which is equipped with different program controllers for different burners. The common program controllers are: LFL series, LAL series, LOA series, LGB series , the main difference is that the time of each program step is different.
The industries where burners are most used include boilers, smelting furnaces, furnaces, heat treatment and other fields, and industries related to heat energy, combustion systems are essential. At present, there is still a certain gap between the technical capabilities of domestic burner manufacturers and foreign manufacturers. The simple external structure and accessories are not complicated, and the core design of the burner head is basically monopolized by foreign products, while almost no domestic manufacturers have serious R&D departments and experimental departments. In terms of the combustion efficiency and service life of the product, there is still a relatively large gap with foreign countries. There is still a certain strength gap between domestic burners and foreign countries, but this also provides a good opportunity for Chinese burners to learn and develop. A series of issues such as quality, technology, and enterprise development speed must have a detailed plan. ensure. The highlight of the burner now lies in energy-saving transformation, safety and technology. These three rings are closely related and interlocking. How to improve the domestic burner market requires the formation of a virtuous circle system in the entire industry, so as to drive development of the entire industry.
Daily maintenance
The maintenance of the burner is actually very simple. In most cases, no special maintenance work is required. Only when the parts are damaged or the combustion efficiency is reduced after a certain period of use, the burner needs to be repaired and repaired. Repair and replacement of components. Routine testing in some special industries is necessary, after all, safety in production is the top priority. Maintenance testing can be roughly divided into:
1. Daily maintenance and maintenance
1) Always keep the surfaces of the equipment clean.
2) When the equipment is stopped, the rotation of the quick-opening blind plate (flange cover) should be lubricated in time according to the regulations, and the lead screw of the opening and closing part should be lubricated. Grease should be applied to other parts as much as possible. Grease parts can be injected with 10# or 20# engine oil.
2. Maintenance and maintenance during operation
1) It is recommended that the operator is responsible for the usual maintenance of the equipment.
2) Always keep the surface of the equipment clean.
3) Monitor the reading of the differential pressure gauge at any time. When the operating pressure difference reaches 0.02Mpa, the filter element should be flushed.
3. Inspection cycle
1) The periodic inspection of this equipment must be carried out in strict accordance with the relevant provisions of Chapter VI of the "Regulations".
2) Conduct a comprehensive inspection of the equipment at least once a year, measure the wall thickness of the equipment, and conduct non-destructive testing on the pressure-bearing welds of the equipment every two years. All inspection and test results shall be recorded in the technical files of the equipment.
3) When there is pressure inside the equipment, no maintenance shall be performed. For maintenance under special circumstances, it is necessary to strictly abide by the provisions of Article 122 of the "Containment Regulations".
4. Maintenance during parking
1) When the equipment is parked, the liquid in the equipment should be drained.
2) Close all valves.
3) Thoroughly clean the surface of the equipment.
4) All rotating parts are coated with anti-grease.
5) Cover all the equipment with canvas to prevent dust from depositing on the surface of the equipment.
