This paper introduces the copper concentrate drying technology in Flash Smelting processes,and compares characteristic and application status between the flash dryer and steam dryer,the result makes know that the steam dryer has evident advantage in terms of equipment investment,energy consumption and environment protection,it is provided with extensive use.

This article mainly introduces and analyses the working principal,technological process,technological parameter,production gain,common troubles of KUMERA steam dryer adopted by No.

Measurement and application of condensed mode steam quality;

Measuring steam quality by injecting incondensable gas;

Steam stimulation is the key technology for heavy oil recovery while steam quality is the main parameter of steam injection technique,so how to improve the down-hole steam quality becomes the core problem in the process of improving the economic benefit of thermal recovery.

Soft sensing and optimization of steam dryness for a steam drive oil process;

The steam dryness can be determined by the ionic analysis of the water sample.

The conventionalsteam drying, the heatpump (dehumidification)drying andsteam-heatpump combined drying are tested and analyzed.

The paper introduces selection,effect after putting into operation,existing problems and reformation conditions of process equipments reconstruction plan of matched copper concentrate steam drying system,dry ore dense phase conveying system and flue dust dense phase conveying system of 350 kt/a expanding reconstruction project of Jinlong Company.
