Is the cost of coal drying using gas high?

   Heat source equipment is an important part of the drying efficiency and quality of coal dryers. If the selected heat source is unreasonable, it will affect the overall production cost and benefit. With the requirement of environmental quality in the dry production of coal, the application of natural gas as a heat source in the drying industry is becoming more and more popular. So, how about coal burning and using gas? Is the drying cost high?

  In the drying operation, we often use coal as the main heat source, because coal burning is not only heat, but also can reach 7,000 calories per kilogram, and the cost of purchasing coal is lower, which can greatly reduce the overall investment cost of the drying line. However, the disadvantage of using coal as a fuel is that a large amount of flue gas and harmful gases such as nitrogen monoxide and sulfur dioxide are generated during the combustion of coal, which poses a great hazard to the environment. This is subject to certain restrictions in today's high energy conservation and environmental protection requirements. Therefore, as a new type of clean heat source, gas is gradually being used in the dry production of various materials.

  Then, when using coal as a heat source when drying coal, is it costly? We have to evaluate this issue in many ways. For example, although the price of a gas-fired heat source when we dry coal is more expensive than the price of coal, the cost of a gas-drying production line is slightly higher than that of a coal-fired production line. However, on the whole, gas as a clean fuel does not pollute the environment during the process of drying the material, and it is of high value to the production line with high cleanliness of the finished product. This is of course much lower cost than using electricity as a heat source. In this way, the use of coal gas drying equipment is still more cost-effective in the long run.

  Here, Zhengzhou Dingli also advises users and friends to purchase suitable drying equipment from regular brand manufacturers, so as to ensure the rationality of equipment quality and production plan, reduce investment costs and obtain greater benefits.
