Title:
APPARATUS FOR DRYING COAL USING REHEAT STEAM
Document Type and Number:
WIPO Patent Application WO/2015/064996
Kind Code:
A1
Abstract:
The present comprises: a first coal dryer; a second coal dryer; and a third dryer, by removing moisture remaining inside and outside of coal, which is used for fueling thermal power plants, in the multiple coal dryers using reheat steam at a high temperature, incomplete combustion of coal can be prevented, thereby enhancing heat capacity of the coal, minimizing release of pollutants, preventing corrosion and enhancing the durability of a system, reducing the rate of spontaneous combustion due to reduced moisture, improving crushing efficiency of a coal pulverizer and heat distribution of a power boiler when coal is combusted, resolving the issue of clogging of a moving pathway when coal is transported, and improving coal supply stability by increasing utilization of low-quality coal for which demand is low. Furthermore, the following advantages can be provided: use of low heat capacity coal which is more affordable than high heat capacity coal; savings in fuel cost and manufacturing cost by reduced coal importation; reduction of waste, pollutants, and carbon dioxide generated from exhaust gas by relative reduction of coal consumption, and the advantages of replacement of foreign technology and exportation of equipment to foreign markets could be anticipated.
