Coal has always been an important natural resource in China, and coal combustion will bring certain pollutants. Therefore, coal-fired boilers gradually transition to gas boilers.

Coal has always been an important natural resource in China, and coal combustion will bring certain pollutants. Therefore, coal-fired boilers gradually transition to gas boilers. However, what is the difference between the two boilers? What? The following summary and analysis are given in terms of economic benefits and social environmental benefits:
Comparative analysis of coal-fired boilers and gas-fired boilers 1. Social environmental benefits: In actual operation, coal-fired hot water boilers have low thermal efficiency, high energy waste, large dust concentration, high sulfur content of coal, and serious air pollution. Especially in recent years, the contradiction between energy supply and demand and environmental pollution has become increasingly prominent. Gas-fired hot water boilers have high thermal efficiency, low air pollution, and good environmental performance. Therefore, from the perspective of social and environmental benefits, coal-fired boilers have a very important role in changing gas-fired boilers.
2. Economic Benefits: Coal-fired hot water boilers use coal. The calorific value of coal is about 5500Kcal/Kg (calculated according to standard coal), and its market price is 460 yuan per ton (the price of coal has an increasing trend, and the purchase and sales channels are not smooth. The 10t hot water boiler consumes 0.2 tons of hot water per ton of hot water, and the price is 92 yuan. The calorific value of natural gas is 8000kcal/Nm3, and the price per cubic meter of natural gas is 2.0 yuan, calculated according to natural gas consumption of 80Nm3 per ton of hot water consumption. The price is 160 yuan.
It can be seen from the above comparison that coal-fired boilers are of low cost, but environmental pollution is large and resources are wasted. Gas-fired boilers are small in pollution and environmentally friendly. However, the cost of use is high. It can be said that both coal-fired boilers and gas-fired boilers can be said. Each has its own advantages, but in this society with increasingly prominent environmental protection concepts, the conversion of coal-fired boilers to gas-fired boilers has certain promotion significance.
