Cost comparison of coal-fired boilers and gas-fired boilers:
Coal-fired boilers, for example, use coal. The calorific value of coal is about 5500 Kcal/Kg (calculated according to standard coal), and its market price is 460 yuan per ton (the price of coal is rising constantly, and the channel of purchase and sale is not smooth. In order to control the current situation of serious energy waste and waste, the price of coal has continued to rise momentum). 10 ton steam boiler consumes 0.2 tons of coal per ton of steam at a price of 92 yuan. The calorific value of natural gas is 8000 kcal/Nm3, and the price of natural gas is 2.0 yuan per cubic meter. The price is 160 yuan based on the consumption of natural gas and 80 Nm3 per ton of steam.
From the above comparison, it can be seen that the operating cost of gas boiler room is slightly higher than that of coal-fired boiler, but gas boiler can greatly improve the working environment, reduce labor intensity and improve enterprise grade. And with the development trend of national environmental protection policy and energy policy, the operation cost of gas-fired boiler has a very large reduction space compared with coal-fired boiler. Therefore, this boiler is very suitable for changing to gas-fired boiler.
