Blast furnace gas burner production process requires heating with heat transfer oil, but existing furnace gas has a large amount of tar, and the import burner cannot operate at all. Many manufacturers have also solved this problem in China. So burner use precautions and classification

Burner use precautions and classification
Main features: A. The burner is made of integral cast aluminum housing. B. The fan has a very strong pressure-resistant special structural design that can make the burner can also operate safely on the half-positive pressure and positive pressure boilers. C. The sliding connection flange on the combustion head allows the installer to make the burning head to the furnace and accurately connect them. D. The structure of the combustion head allows the burner to obtain the best combustion matching E, electronic devices control the entire operation process and security function. F, many models, wide capacity. G, easy to install and maintain. H, the low nitrogen burner is equipped with complete installation and facilitates on-site connection. Hundreds of combustors have primary, two-poles, gradual two-stage and proportional arductors that have been gradually gradually (the latter is proportional to regulation). A, level 1: The burner only has on / off function. B, two levels: burner runs relevant discontinhes, open flames and maximum thermal power functions, and automatically returns from the maximum thermal power position (via a special thermostat or pressure switch control to a small flame operation). C, progressive two-stage formula (DSPG): The gradual two-stage burner can operate in two different thermal power levels, with a special sensor (thermostat or pressure switch) within a certain time interval from a thermal power Convert to another heat power, the time interval is required by the servo motor to control the heat power from the minimum conversion to the maximum (vice versa). Air / fuel is extremely accurate in the entire operating range (from minimal to maximum) according to the specific requirements of the boiler. Adjusting operation: Proportional adjustment burner is used to constantly changing the thermal power due to the special requirements of the boiler load, which is achieved by the DSPG of the automatic thermal power regulator (RWF40), which is implemented. The latter is controlled by means of sensors (temperature or pressure) and field matches (mounted in the RWF32 regulator) to control the adjustment servo motor to increase or reduce the purpose of thermal power output. The RWF40 regulator is a PID (scale, integral, differential) type. The adjustment set value is adjusted by the adjustment pointer of the RWF40 mounted on the burner. Naturally, the thermal power level can only vary within the "maximum" and "minimum" limiting value of the burner. Proportional adjustment is to use a servo motor that allows the proportion of air / fuel to be taught at any time in the entire proportional adjustment range. Industrial Burner Series: GI Series in Large Systems. The GI series industrial burners are designed for industrial applications, which are structurally integrated (therefore more compact than the common burners of the same thermal power) capacity range from 1581 to 7316kw. In addition to the GI burner, the industrial series burner has a larger capacity: TS series with separate fan, a PYR series with a separate fan with an adjustable flame. Burner Classification: Fuel burner, gas burner, oil and gas dual-use burner burner debugger: 1 before debugging: 1, see if gas is in place, is clean and smooth, whether the valve is turned on. 2, there is no pipeline disclosure, whether the pipeline installation is reasonable. 3, venting from the front of the gas valve to ensure that there is no mixed air in the pipeline, and the venting pipe should be removed from outside. Internal inspection of burner: 1, whether the burner burner is installed and adjusted. 2. Whether the direction of the motor rotates is correct. 3. Whether the external circuit connection meets the requirements. 4, according to the line situation, the burner is coldly simulated, and whether the various components of the equipment in operation are normal and whether the flame detection protection portion is normal. Burner debugging: 1. Check if the external gas is in place, whether the pipeline is smooth, and the external power supply is in place. 2. Turn the load of the burner to the small load. The ignition position is adjusted to a small load, turn off the large load for ignition and observe the flame conditions, and the servo motor or damper according to the flame conditions. Note: 1 2, the air supply pipe is strictly prohibited to use a wrench or metal rod to strike, friction, avoid causing static or spark, causing gas explosion. 3. It is strictly forbidden to smoke, weld, cut, cutting, etc. in the air supply valve group or pipeline flange. 4. It is strictly forbidden to make any open fire testing next to the pipeline and valve group and pressure regulating valve to avoid major accidents. 5. Test if there is a fuel in the air supply line, usually test the gas low pressure gauge. 6. In the air supply line, it is over-emptied, but the wall has a residual gas or droplets, and it will cause combustion and explosion in case of electrostatic sparks and open flames. 7. When the air supply line has been ventilated, the valve group needs to be disassembled, first of all, the front-end valve front end valve must be cut, and then the gas body in the valve group is taken off, and then the valve dismount Maintain. 8. In debugging, gas must be serious, safe and efficient. 9. It is forbidden to use no explosion-proof electrical power tools on site. 10. The VPS504 leak detector must check the valve group before use. 11.6 million cards and above combustors are recommended to use VPS504 leak detects, such as users do not match, thereby triggering the responsibility of accident customer responsibility
