METHOD OF CLINKER COOLING CONTROL IN GRID COOLER Russian patent published in 2012 - IPC C04B7/47 F27B7/38 F27D19/00 

FIELD: process engineering.

SUBSTANCE: invention relates to control over processes in roasting of materials in rotary furnaces with bar coolers and may be used in production of construction materials. Proposed method comprises measuring cooler operating parameters, defining relationship of the latter for them to be optimised. Note here that secondary air temperature and clinker temperature on hot grid are used as cooler operating parameters. Heat transfer factor in air filtration through clinker layer is used as ratio of operating parameters that represents secondary air temperature-to-clinker temperature on hot grid ratio. Operating parameters are optimised by maintaining heat transfer factor at maximum level.

EFFECT: higher process performances.
