ABSTRACT

Rotary dryers are generally preferred for industrial coal drying operations. However, the initial investment and maintenance costs of rotary dryers are quite high. There is also the risk of spontaneous combustion and ignition of coal in such dryers. In this context, carbonic film technology comes to the forefront when an environmentally friendly drying system with low initial investment cost and no risk of ignition of coal. Low-temperature drying can be performed using carbonic film technology. However, there are no dryer systems drying with this technology. The aim of this study is to design a new dryer with carbonic film heater. With the carbonic dryer (CDC) designed as a result of experimental studies, the total energy to be spent for the removal of 9% moisture from 1 ton coal was found to be only 50 kWh. Furthermore, the FIR heating carbonic film is efficient for drying thin-layer coal and is inefficient at high layer thickness.

摘要

工业煤干燥操作通常优选旋转干燥机。但是，回转式干燥机的初期投资和维护成本相当高。在这种干燥器中还存在煤自燃和着火的风险。在此背景下，碳膜技术应运而生，因为它是一种环保型干燥系统，初期投资成本低，且无燃煤风险。可以使用碳膜技术进行低温干燥。但是，没有采用这种技术进行干燥的干燥系统。本研究的目的是设计一种带有碳膜加热器的新型干燥机。使用根据实验研究设计的碳化干燥器 (CDC)，发现从 1 吨煤中去除 9% 水分所花费的总能量仅为 50 kWh。此外，
