There are many cheap methods for drying coal. Among them, high-temperature hot air and low-temperature steam drying coal are more commonly used, both of which can quickly dry coal plant wet coal to within 15% (adjustable) and improve coal quality and calorific value. So which of high temperature hot air drying and low temperature steam drying is low cost? This article introduces you coal rotary dryer:
Which method of high-temperature hot-air drying or low-temperature steam drying is cheaper and cheaper depends on the user’s existing heat source or convenient heat source. If the user has abundant steam resources, low-temperature steam should be used to dry the coal. Coal is cheaper. Steam waste heat or flue gas waste heat belongs to the recycling of waste resources. At the same time, because steam drying is an indirect drying process, there are no three wastes generated during the drying process, so the dust removal equipment of coal dryer does not need to be too high. For users who have natural gas, coke oven gas, gas, coal and other heat sources, it is recommended to use high-temperature drying technology. Professional technicians can flexibly match dust removal equipment according to user cost requirements and the environmental assessment standards of the user’s location to optimize rationally. At the same time, the production line promotes the emission of dust and tail gas to meet the standard, ensuring the efficient, high-quality and low-cost operation of coal drying.
Zhengzhou Dingli, as a large-scale coal dryer direct sales manufacturer in Henan, can provide users with coal dryer equipment that can process 10-1000 tons per hour. One-to-one design and planning of coal-fired slime drying, steam coal drying, and gas The configuration of coal drying, fuel coal drying and other production lines provides users with a cheaper method of coal drying and reduces the investment cost of coal drying production lines.
