What are the six major parts of the burner？News | 2020-09-15 10:57
1. Main Structure
This part constitutes the main structure and outline of the burner. It includes a housing and related parts, and other functional system products are installed on the main structure.
2. Control System
This part of the product includes controllers, servo mechanisms (motors and hydraulic cylinders), flame monitors, pressure or temperature switches, etc. Controller: The core part of burner control, including the process management controller called the proportional regulator, the gas leak detector responsible for detecting valve leaks, etc., are responsible for collecting and triggering the signals of each action, which is equivalent to the burner's brain. Commonly used brands are SIEMENS, BRAHMA, HONEYWELL, etc. Among them, SIEMENS is widely imitated, and its level of simulation is high. As an editor of the industry, most of the 400 LOA24 ordered in 2004 were counterfeit products. Servo mechanism: All electric servo motors and mechanically driven hydraulic cylinders are classified as control systems. The reason is that the former and the program controller form a closed-loop control system, while the latter’s power source comes from the oil pump, and the instructions for its execution are actually Triggered by the controller, and control the opening and closing of the damper. This product is currently not completely imitated in China, but there is one in the legend, and I have not seen it. Flame monitor: This name is more and more deviated from the actual function name by the popular name in the industry, and finally confused with the controller that controls the opening and closing by the flame signal only in the controller category-the actual flame can be monitored The photoresistor, photoelectric tube, and ion probe for detecting flame ions should obviously be called a controller if they can turn on and off the power by themselves. As in all industries, all buyers only care about spending the least money to buy the best things, all sellers only care about getting more profits with less cost, and what is the origin of the subject matter? Only no one pays attention, it becomes the last section. The QRB1, QRB3, QRA2, FC13 and other products with larger dosages in the photocells have been copied. Among them, QRB1 has been quite popular because of its stable quality. The editor has not seen SIEMENS QRB1 for three years. Pressure and temperature switch: In a broad sense, it should be called a pressure or temperature sensor. Among them, the gas switch in the pressure switch: the gas switch, which is mostly used for the gas control of the gas burner, and the air pressure switch is used to control the air (if there is no forced air supply and the air pressure is generated, the power of the whole machine is cut off). Temperature switches are mostly used to control the heating temperature of high-viscosity fuels, such as heavy oil or residual oil.
3. Ignition System
This part of the product includes ignition transformers, ignition electrodes, high-voltage wires. Ignition transformer: a product used to generate high-voltage current and discharge through the electrode tip to ignite the burner. This is a low-tech product, and at the same time it is regarded as a low-tech product to imitate. Ignition electrode: Let alone a product with any technical content, unless the shape is too weird and too little is used, the editor will not store the original product, and will not recommend the user to use it. High-voltage line: It's just a high-temperature, high-voltage power line. Why should I import it? Not to mention the original ones.
In common burners, only the electric motor should be related to power.
5. Fuel Supply System
On the burner, this is one of the more complicated systems. In fact, the mechanical products involved in this system are far more complicated than the electrical products on the control system. Fuel pump, fuel nozzle, fuel heater, fuel cup, fuel pipe, fuel solenoid valve, gas valve (including gas solenoid valve), gas pressure regulator, gas filter
The most technical system in the burner industry. In fact, no matter how sophisticated the electrical products that are responsible for the control, or how sophisticated the oil pump is, the level of these technologies and methods have nothing to do with the burner manufacturer’s own capabilities, but the design of the combustion system requires them to be self-reliant. of. Therefore, the level of the combustion system determines the ability of a burner. This part of the product includes combustion canister, forced air blower impeller, flame plate, oil gun, gas core tube, and built-in or external diffuser. This part of the product constitutes an air-fuel premixing device.
