Compared with coal-fired boilers, what are the advantages of gas-fired boilers?

Coal-fired boilers have always occupied half of my country's boiler market and played an important role in my country's industrial production. However, with the emergence of environmental pollution, coal-fired boilers, as serious pollution equipment, have also received attention and treatment from environmental protection departments. Small and medium-sized coal-fired boilers have gradually withdrawn from the market in recent years. Gas boilers that integrate cleanliness, environmental protection, and high efficiency have been widely promoted and used. In recent years, the frequency of users' use has increased year by year. So, compared with coal-fired boilers, what are the advantages of gas-fired boilers? Let Zhengzhou Fangkuai Boiler Factory answer for you.

Why do so many people choose to use gas boilers? The specific reasons are as follows:
       1. The gas boiler burns completely, and the exhaust gas is pollution-free. The exhaust gas blackness of the gas boiler is 0 Ringelmann level, the SO2 content is very small, and the combustion efficiency can reach more than 99%;
       2. The gas boiler is easy to start and stop, and the temperature rises quickly. For the boiler that runs intermittently, the heat loss during the compression process can be omitted, which is beneficial to improve the thermal efficiency. Of course, due to the rapid temperature rise, the temperature of the furnace body changes drastically, which is detrimental to the life of the boiler.
       3. The fuel gas is completely burned, no fly ash, no particles scouring the furnace body like coal-fired boilers, and no ash on the heat transfer surface, which is good for heat transfer, and from this aspect, it is also good for prolonging the life of the furnace body.
       4. Gas fuel is transported by pipeline, and there is no ash and slag after combustion, which can save the coal storage yard and slag storage yard of coal-fired boilers. This is particularly important for large and medium-sized cities with little land; coal-fired boilers can be removed. The coal transportation system and slag removal system greatly reduce labor intensity and reduce urban transportation.
       5. The calorific value of the gas is stable, and the flow can be easily adjusted through the flow regulating valve, which is convenient to realize the automation of the production process, and the adjustment accuracy is high. It can be seen from the above five points that gas-fired boilers do have incomparable advantages over coal-fired boilers. Changing the fuel structure and vigorously developing the gas industry is an inevitable trend of social development.
