With the progress of modern society, the application of gas-fired boilers in the current society is becoming more and more common. However, as a kind of mechanical equipment, gas-fired boilers will generate energy consumption during operation, which will cause certain harm to the environment, which is not conducive to sustainable development of the modern economy. Under the current social development situation, as one of the sources of environmental pollution, gas-fired boilers have very high requirements for their selection and use. In order to better promote sustainable economic development, it is of great significance to pay attention to the selection of gas-fired boilers and the design of energy saving and consumption reduction.

 

The 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 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 better economic performance and are widely used in the current social development process.

 

In this fast-developing society, social development calls for more and more energy saving and consumption reduction. As a kind of equipment, the environmental problems arising from the operation of boilers have seriously restricted the development of modern society and economy. The threat to the living environment will inevitably lead to various social problems, which is not conducive to the sustainable development of modern society and economy. The gas boiler is the main fuel for water, the heat emission can be recovered, and the degree of environmental pollution is small. The selection of the gas boiler not only meets the needs of modern social and economic development, but also meets the requirements of the sustainable development strategy. Economic development has an irreplaceable role.

 

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 in the design of energy saving and consumption reduction in the selection of boilers to ensure stable boiler performance.

 

Principles of selection of gas boilers



1 Principles of environmental protection and energy saving


As a kind of mechanical equipment, gas boiler uses combustion energy as power to drive the operation of equipment during operation. While bringing benefits, gas-fired boilers also have certain negative impacts. Among them, the most prominent ones are the problems of environmental pollution and energy shortage. With the proposal of sustainable development strategy, the call for the development of environmental protection economy and energy saving economy is getting higher and higher. In order to better promote the sustainable development of modern social economy, the principles of environmental protection and energy saving must be fully implemented in the selection of gas boilers , Do a good job in energy saving and consumption reduction design in product settings, and then design a gas boiler that is suitable for the development of my country's modern society.

 

2 Technical principles


The selection of gas boilers is a highly technical work. Only by ensuring the stable performance of gas boilers, can the due role of gas boilers be better realized. The working medium, capacity, parameters and automatic adjustment performance of the boiler should meet the heat demand of customers, and the capacity and parameters can effectively adapt to the change of heat load. In order to meet the needs of social development, the finalized products that meet the boiler safety technical supervision regulations and pass the production identification should be selected.

 

3 Principles of suitability


There are many types of gas-fired boilers, and different gas-fired boilers have different fields of use and scope. Therefore, when selecting gas-fired boilers, the principle of applicability must be adhered to, and appropriate and suitable gas-fired boilers must be selected according to the supply of local fuel resources. In order to maximize the economic benefits.

 

4 Security


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

 

Application of gas boiler

 


1 Recycling of residual smoke


Compared with other boiler equipment, gas-fired boilers have less heat emission. At the same time, the residual smoke recovery device installed at the discharge port of the gas-fired boiler is used to transform the heating surface at the rear of the boiler and expand the heating surface 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 boiler system, which is specially responsible for the drainage recovery treatment of electric boilers. When the gas boiler is operating, the recovery device can recycle the water heat in the gas boiler system to reduce the heat release of the boiler. At the same time, the recovered heat can be used for other purposes, such as heating and so on.

 

2 Improve economic efficiency


The economic benefit of gas-fired boilers is higher than that of coal-fired boilers: gas-fired boilers use a higher furnace heat load, thereby reducing the volume of the furnace. Gas boilers do not have problems such as contamination, slagging, and wear of the heating surface, so a higher smoke velocity can be selected to reduce the size of the convection heating surface. In this way, the heat energy taken by the flue gas is less, and the thermal efficiency of the boiler is also higher. 


By rationally arranging the convection tube bundles, the gas-fired boiler has a compact structure, smaller size and lighter weight than the coal-fired boiler of the same capacity, and the equipment investment is significantly reduced. And because gas boilers do not need to be equipped with auxiliary equipment such as soot blowers, dust collectors, slag extraction equipment and fuel dryers, the investment cost of auxiliary equipment is much lower than that of coal-fired boilers. There is also no need for fuel processing and preparation equipment before supplying combustion, which greatly simplifies the system. Since gas boilers use natural gas transported by pipelines as fuel, gas boilers do not need fuel storage, saving many costs such as transportation costs, site storage and labor management, so this cost is more economical than coal-fired boilers.

 

3 Improve environmental benefits


With the rapid development of social economy, its environmental problems are also increasingly prominent, which has caused great harm to people's healthy life. As a kind of industrial equipment, gas boiler has low energy consumption and small heat emission, which can greatly reduce the pollution to the environment. In gas-fired boiler equipment, all parameters and indicators of the boiler have been certified by quality. There is no pollution during operation and little damage to the environment.


At the same time, the fuel of gas-fired boilers 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 conducive to slowing down the greenhouse effect and suppressing 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, coordinating the balanced development of environment and economy.

 

Conclusion


In this rapidly developing society, gas boilers are used as a kind of mechanical equipment, and the use of gas boilers has become more and more popular. 

 

While gas-fired boilers bring benefits, the environmental problems they bring are becoming more and more prominent. Under the current social development situation, automatic control of energy-saving boilers is imminent. During the operation of gas boilers, it is of great significance to realize the green operation of gas boilers. With the proposal of sustainable development strategy, the call for the development of energy-saving economy, environmental protection economy and green economy is getting higher and higher.


 As a kind of energy-consuming device, gas-fired boilers must pay attention to its selection work and select products for gas-fired boilers. Boilers with excellent quality and excellent technology will promote the development of modern society and economy.
