With the innovation of industry and the progress of science and technology, the era of steam has passed. A more advanced and energy-saving heat generation machine has entered people's life, that is, the popular gas boiler. In today's era, what kind of role does gas boiler play in our life and what kind of convenience can it bring us? To solve this problem, consumers need to understand the three major uses of gas-fired boilers.

一、商用：目前商用燃气锅炉主用途是为超市、医院、学校、宾馆、小区、洗浴等，提供供暖或洗浴用水、生活热水。由于燃气中的灰分、含硫量和含氮量比煤低，燃烧充分，烟气中粉尘量极少，排放易达到国家对燃气设备所要求的标准，可大大减轻对环境的污染，环保性能好。燃并且气锅炉不需要上煤气、除渣机、除尘机、炉排等附属设备，节约锅炉设备投资，因此适合于商用。

1、 Commercial use: at present, the main purpose of commercial gas boiler is to provide heating or bath water and domestic hot water for supermarkets, hospitals, schools, hotels, communities, bath centers, etc. Because the ash content, sulfur content and nitrogen content in the gas are lower than that in the coal, the combustion is sufficient, and the dust content in the flue gas is very small, the emission can easily reach the national standard for gas equipment, which can greatly reduce the pollution to the environment, and the environmental protection performance is good. Gas fired boiler does not need gas, slag remover, dust remover, grate and other auxiliary equipment, saving the investment of boiler equipment, so it is suitable for commercial use.

二、工用：厂家直销的燃气锅炉使用管道输送的燃气为动力，不需要燃气储存，卫生条件好，可极大的减小劳动强度，改善劳动条件，降低运行成本，节约运行费用、场地和劳动力。由于烟气污染小，对流管束承受的腐蚀小，传热效果好，热辐射能力强，排烟温度低，热效率明显提高，因此工业燃气锅炉主要用于发电，工业燃气锅炉使用的可燃气一般是天然气、高炉煤气、发生炉煤气等。

2、 Industrial use: the direct gas boiler of the manufacturer uses the gas delivered by the pipeline as the power, does not need gas storage, and has good sanitary conditions, which can greatly reduce the labor intensity, improve the labor conditions, reduce the operation cost, and save the operation cost, site and labor. Because of the small pollution of flue gas, the small corrosion of convection tube bundle, the good heat transfer effect, the strong heat radiation ability, the low temperature of exhaust gas and the obvious improvement of thermal efficiency, the industrial gas-fired boiler is mainly used for power generation, and the combustible gas used in the industrial gas-fired boiler is generally natural gas, blast furnace gas, producer gas, etc.

三、民用：家用燃气锅炉主要用于家庭日常生活热水，洗浴热水及供暖。在减少设备维修保养方面，燃气锅炉燃烧系数设备简单，因而需要维修保养的设备少，受热管件使用寿命长，燃气锅炉操作简单，易实现自动控制。因此，燃气锅炉是家用供热的理想选择。

3、 Civil use: domestic gas boiler is mainly used for domestic hot water, bath hot water and heating. In terms of reducing the maintenance of equipment, the combustion coefficient equipment of gas boiler is simple, so there are few equipment to be maintained, the service life of heated pipe fittings is long, the operation of gas boiler is simple, and it is easy to realize automatic control. Therefore, the gas boiler is the ideal choice for domestic heating.

了解了燃气锅炉的三个用途以后，相信消费者对于如何选择好的燃气锅炉应该有了更清晰的认识，即首先要明确用途，再进行实地的比较与挑选。只有如此，消费者才能选择到适合的燃气锅炉，才能更好的发挥它的用途和功效。

After understanding the three uses of gas-fired boiler, I believe that consumers should have a clearer understanding of how to choose a good gas-fired boiler, that is, first of all, to define the use, and then to carry out field comparison and selection. Only in this way, consumers can choose a suitable gas boiler, in order to better play its use and efficacy.
