Gas burner operation Because the main fuel of gas burners is natural gas, liquefied petroleum gas, city gas and other combustible gases. These fuels are flammable and explosive dangerous gases. Safety should be paid great attention to during use and storage, otherwise major safety hazards will occur. accidents.
(1) Start-up operation
Before debugging the newly installed furnace, you should carefully check whether the gas meets the requirements of the burner. Check whether the detection instruments on the gas supply pipeline are normal and whether the pipeline valve switches are normal and whether it is convenient for future use and maintenance. .
Newly installed pipelines should carefully check the installation reliability of all pipelines and the tightness of the pipelines.
Users who use a separate gasification station must ensure that the gas supply volume and gas supply parameters meet the requirements for safe combustion.
Operators must carefully read the equipment instruction manual and master the knowledge and methods of safe operation.
Before starting the machine for the first time, check whether the gas valve is open, otherwise the burner will not work.
Press the power control button on the control cabinet. At this time, the digital display will display the current temperature in the furnace. This temperature of the newly installed furnace body is the ambient temperature.
The fan installed on the furnace body works when the fan control button is turned on. At this time, if the fan is damaged, the control cabinet will be automatically protected from entering the next step.
When the gas fan works without abnormality, restart the combustion control button. At this time, the combustion program controller starts to work. It carries out ignition, air supply, flame detection and other procedures through a certain program to finally achieve safe combustion.
When the combustion controller receives a signal that is not conducive to combustion (for example, there is a problem with the ignition failure, unstable air pressure circuit) or other problems, the combustion controller will immediately turn off the gas and send out an alarm signal.
If the combustion controller alarms, it must be manually reset by the operator after the fault is resolved before it can continue to work.
Operators of each piece of equipment should refer to the furnace safety operating procedures and production process requirements for operation.
When the production process requires adjusting the control temperature, the operator should refer to the instructions of the smart CNC meter for adjustment.
(2) Shutdown operation
There are two situations for shutdown. The first is to automatically shut down when the temperature in the furnace reaches the set value. At this time, the operator does not need to do anything and wait until the temperature in the furnace is lower than the set value. The device will power on automatically.
The second is that during manual shutdown and shift handover shutdown, the operator should shut down the machine in the reverse order of startup (turn off the combustion control button, turn off the fan button, and then turn off the power button).
When the shutdown time is long, the operator should close the gas pipeline valve to avoid gas leakage.
Main features of domestic gas burners
Domestic gas burners are still in the research and exploration stage, mainly because of safety and quality issues, because gas is different from other fuel burners. Once the gas leaks, it will interact with pulverized coal or oil burners. The degree of risk is completely different, but the domestic development speed is quite fast. During the 11th Five-Year Plan, a group of small and medium-sized enterprises with technical strength emerged, such as Beijing Kaimingyang. The reason why its burners have become one of the few burner brands in China that can sell well abroad. The manufacturer's propaganda plays a certain role, but the main reason is that the advanced gas and air premixed, semi-premixed and turbulent blended reflow combustion technology is used in the design, thereby improving the combustion efficiency, increasing the combustion intensity and flame stability, which happens to be foreign ( For example, Riello Ego, etc.) gas burners have the same effect, but due to the low cost value in China, they are at a low price abroad. Regardless of whether there are problems with this sales model, it is also an international market opened up by high technology and low price. The reflow zone staged ignition combustion technology is used to enhance the combustion of low calorific value gas. Its optimized burner structure and random design of flame shapes with different brazier bricks can make the flame shape form a cylindrical, rigid, flat shape attached to the wall to ensure the uniformity of the temperature field in the furnace. The flame shape and flame length can be designed according to user requirements. Reliable noise reduction measures reduce noise to meet environmental requirements. It is undeniable that there is still a certain strength gap between domestic gas burners and foreign countries, but this also provides a good opportunity for Chinese gas burners to learn and develop. A series of issues such as the development speed of quality technology enterprises must have a detailed plan. ensure. The highlight of gas burners now is energy saving, safety and technology. These three links are closely related. How to improve the domestic gas burner market requires the entire industry to form a virtuous cycle system to drive the development of the industry.
Zhengzhou Zhongcheng Burner Engineering Technology Co., Ltd. focuses on the development of clean energy combustion equipment. Among them, the burner products and fuel-to-gas conversion projects launched by the company are favored by the market. Especially in the field of converting burner oil to gas, we have always maintained leading technology. In recent years, with the rise in international crude oil prices and energy pollution and other factors, the global focus has focused on the issue of clean energy to reduce emissions. Therefore, many clean energy sources have gradually come to the fore, such as natural gas, methanol, etc. Natural gas is increasingly used in my country. Civil and industrial natural gas pipeline projects are also gradually improving. In order to cooperate with the international and domestic development trends, Youster Company vigorously develops the burner oil-to-gas business. Especially in the renovation of small and medium-sized burner projects, we have rich experience. Renovated brands such as Riyadh, Luviso, BadDecker, Ego, Olympia, Zhengying, Honeywell, etc. The renovated equipment has stable performance and low transformation costs.
