The environmental protection cost of gas-fired boilers is low. The operating cost of the boiler covers fuel, thermal efficiency, labor and other expenses. The development of gas-fired boilers is also a general trend in terms of environmental protection, and is an important manifestation of clean energy:

　　1. Fuel, the rise of natural gas in boilers has a lot to do with its own characteristics. Natural gas is a clean energy source. After combustion, it produces carbon dioxide and water, and the price per cubic meter is relatively low. At the same time, gas is supplied through pipelines by gas companies. The safety of use has been greatly improved.

　　2. Thermal efficiency. Gas-fired boilers are the highest among all current boiler models. Ordinary gas-fired boilers can reach more than 98%, and the condensing unit can achieve thermal efficiency of more than 99%. The fuel is fully utilized and the boiler performs well.

　　3. Fuel procurement. In the past, boiler fuels such as coal, fuel oil, biomass, etc. required companies to purchase, transport and store in real time, and labor costs, storage space costs, and fire safety costs combined were high.

　　4. Labor cost. The gas boiler has a high degree of automation. The start-stop time can be set to realize unattended operation, without manual feeding, slag removal and other operations, and the entire process of fuel and water supply is intelligently controlled.
