　　While my country's economy is developing, the problem of energy shortage has become increasingly prominent, and it affects the healthy development of my country's economy. With the progress of modern society in my country, the application of gas boilers in the current society of our country is becoming more and more common. However, gas boilers, as a kind of mechanical equipment, will generate energy consumption during operation, which will cause certain harm to the environment of our country. Furthermore, it is not conducive to the sustainable development of our country's modern economy. Under the current social development situation, our country pays more and more attention to environmental protection. As one of the environmental pollution sources in our country, gas boilers have very high requirements for their selection and use. In order to better promote the sustainable development of our country’s economy, we pay more attention to gas boilers. Model selection and energy-saving and consumption-reducing design are of great significance.

　　1 Importance of gas boiler selection

　　As a kind of industrial equipment, gas boiler refers to the equipment that uses various medium fuels to heat the liquid contained to certain parameters and output heat energy to the outside. Gas boilers include gas boiling water boilers, gas hot water boilers, gas steam boilers, etc. Compared with oil boilers and electric boilers, gas boilers have good economic performance and are widely used in the current social development process. In this fast-developing society, social development calls for energy saving and consumption reduction. As a kind of equipment, the environmental problems caused by the boiler during its operation have severely restricted the development of my country’s modern society and economy. The threat to the environment that people depend on will inevitably lead to various social problems, which is not conducive to the sustainable development of our modern society and economy. The gas boiler is the main fuel for water, the heat emission can be recycled, and the degree of environmental pollution is small. The selection of gas boiler not only meets the needs of my country's modern social and economic development, but also meets the requirements of my country's sustainable development strategy. , Has an irreplaceable effect on the social and economic development of our country. Under the current social development situation, the use of gas-fired boilers is becoming more and more common. In order to better promote the development of our society, it is necessary to do a good job of energy-saving and consumption-reducing design in the selection of boilers to ensure stable boiler performance.

　　2 Principles of gas boiler selection

　　2.1 Principles of environmental protection and energy saving

　　As a kind of mechanical equipment, the gas boiler uses combustion energy as the power to drive the operation of the equipment during its operation. While the gas boiler brings benefits, it will also produce certain negative effects. Among them, environmental pollution and energy shortage are the most prominent ones. As the sustainable development strategy is put forward, the call for the development of an environmentally friendly economy and an energy-saving economy is getting higher and higher. In order to better promote the sustainable development of my country’s modern society and economy, it is necessary to fully implement environmental protection and energy saving in the selection of gas boilers. The principle is to do a good job of energy saving and consumption reduction design in the product setting, and then design a gas boiler suitable for the development of my country's modern society.

　　2.2 Technical principles

　　The selection of a gas boiler is a highly technical task. Only by ensuring the stable performance of the gas boiler can the gas boiler function better. The boiler work cut-off, capacity, parameters, and automatic adjustment performance should meet the customer's heat demand, and the capacity and parameters can effectively adapt to changes in the heat load. In order to meet the needs of social development, finalized products that meet the boiler safety technical supervision regulations and pass the production appraisal should be selected.

　　2-3 Principle of Applicability

　　There are many types of gas boilers, and different gas boilers have different application fields and scopes. For this reason, when choosing gas boilers, you must adhere to the principle of applicability, and choose appropriate and appropriate gas boilers according to the local fuel resource supply. And then realize the maximization of economic benefits.

　　2.4 Security

　　As a kind of mechanical equipment, gas boilers often have some faults during operation, such as flameout, overpressure, overtemperature, power failure, scaling, corrosion, etc., which will cause a series of safety accidents, such as pipe bursts , Leaks, etc. For this reason, the working medium, parameters, and capacity of gas-fired boilers are not allowed to meet the heat demand, and they are designed in strict accordance with relevant design regulations to ensure the safe use of gas-fired boilers.

　　3 Application of gas boiler

　　3.1 Recycling of residual smoke

　　Compared with other boiler equipment, gas boilers have less heat emissions. At the same time, a residual smoke recovery device is installed at the discharge port of the gas boiler. The heating surface at the tail of the boiler is modified, and the heating surface is expanded to increase the heat exchange area. Enhance the heat exchange effect, so as to achieve the effect of reducing the exhaust gas temperature and realize energy saving and emission reduction. During the operation of the gas boiler, ensuring sufficient water is a prerequisite for the normal operation of the boiler, and the quality and quantity of water have a direct impact on the performance of the gas boiler. In order to improve the utilization efficiency of water resources, a water circulation process can be added to the gas-supply boiler system, which is specifically responsible for the recovery and treatment of wastewater from the electric boiler. When the gas boiler is in operation, the recovery device can recycle the water heat in the gas boiler system and reduce the heat release of the boiler. At the same time, the recovered heat can be used for other purposes, such as heating.

　　3.2 Improve economic efficiency

　　The economic benefit of gas boilers is higher than that of coal-fired boilers: the furnace heat load of gas boilers is higher, which reduces the volume of the furnace. The gas boiler does not have the problems of heating surface pollution, slagging, abrasion, etc. Therefore, a higher smoke velocity can be selected to reduce the size of the convective heating surface. In this way, the heat energy taken away by the flue gas is less, and the thermal efficiency of the boiler is also higher. By reasonably arranging the convection tube bundle, the gas boiler has a compact structure, smaller size and lighter weight than a coal-fired boiler of the same capacity, and the equipment investment is significantly reduced. Because gas boilers do not need to be equipped with auxiliary equipment such as soot blowers, dust collectors, slag discharge equipment and fuel dryers, the investment cost of auxiliary equipment is much lower than that of coal-fired boilers. There is no need for fuel processing and preparation equipment before supplying and burning, which greatly simplifies the system. Because gas boilers use pipelined natural gas as fuel, gas boilers do not need fuel storage, saving transportation costs, site storage and labor management, etc., so this cost is more economical than coal-fired boilers.

　　3.3 Improve environmental benefits

　　While our country's social economy has achieved rapid development, its environmental problems have become increasingly prominent, which has caused great harm to people's healthy lives. In order to restore a healthy living environment for human beings, our country's appeal for environmental economic construction is getting higher and higher. As a kind of industrial equipment, gas boiler consumes less energy and emits less heat, which can greatly reduce environmental pollution. In the gas-fired boiler equipment, the parameters and indicators of the boiler have passed the quality certification, which is pollution-free during operation and has little damage to the environment. At the same time, the fuel of the gas-fired boiler is mainly water, which not only reduces the consumption of standard coal, but also At the same time, it also reduces carbon dioxide emissions, which is beneficial to slowing down the greenhouse effect and restraining the environmental trend of global warming. In this era of rapid economic development, the use of gas boilers not only contributes to my country's environmental protection, but also provides a guarantee for my country's social and economic development, and harmonizes the peaceful development of my country's environment and economy.
