Industrialization of steam coal humidity control technology

A few days ago, the 2012 national major scientific and technological achievement transformation project undertaken by Tianhua Institute - "Industrialization of Coal Humidity Control by New Steam Pipe Rotary Cylinder Drying Method" passed the verification
of the special inspection team of the Ministry of Finance's achievement transformation project.
At present, the technology has built 5 sets of large-scale coal humidity control devices in several domestic enterprises, and has achieved significant economic and social benefits
.

Coal humidification technology is a kind of pretreatment technology for coking coal, that is, through the drying of coking coal, reduce and stabilize the moisture of the furnace coal, to improve the production capacity of coke oven, reduce coking energy consumption, improve coke quality and stabilize coke oven operation, its core technology is steam pipe rotary drying process and equipment
。 The steam pipe rotary drying coal humidification technology developed by Tianhua Institute is currently a coal humidification technology with the largest single machine processing capacity, the longest continuous operation time, the most stable performance, and the most significant energy saving and emission reduction benefits in China, which has obvious advantages in the stability, large-scale, automation, completeness and safety performance of this technology, and has surpassed foreign imported technologies in many fields, and the technical level has reached the international leading
.
The success of this technology has broken the monopoly of foreign suppliers of steam pipe rotary drying equipment, saved a lot of equipment costs for China, and also guaranteed after-sales service time and costs
