Mill e.g. roller mill, for milling e.g. powdered brown coal in coal-fired power plant, has distribution devices comprising blowing devices for blowing gas/vapor upstream of dust pipeline or into mill inner sided opening region of pipeline

摘要

#CMT# #/CMT# The mill has a dust pipeline (10) guided to an attached burner, and distribution devices (14, 14a, 14b) provided for distribution of dust to the dust pipeline. The devices comprise blowing devices (36, 36a, 36b) for blowing gas and/or vapor upstream of the dust pipeline and/or into a mill inner sided opening region of the dust pipeline. Each blowing device is attached to the dust pipeline. A measuring sensor (110) is provided for detecting predetermined characteristics value of a medium, which flows into the dust pipeline. #CMT# : #/CMT# An independent claim is also included for a method for influencing distribution of dust to a dust pipeline. #CMT#USE : #/CMT# Mill e.g. roller mill and tubular pebble mill, for milling goods i.e. powdered coal (all claimed) e.g. powdered brown coal and hard coal in a power plant e.g. coal-fired power plant, hard coal power plant and brown coal power plant. #CMT#ADVANTAGE : #/CMT# The devices comprise blowing devices for blowing gas and/or vapor upstream of the dust pipeline and/or into the mill inner sided opening region of the dust pipeline, thus influencing distribution of dust to the closed dust pipeline without providing wear suspected guiding elements in the dust pipeline. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial schematic sectional view of a mill. 10 : Dust pipeline 12 : Flow path device 14, 14a, 14b : Distribution devices 36, 36a, 36b : Blowing devices 110 : Measuring sensor.
