The present work applies an original ash deposition model to a MW TH combustor burning pure coal and its blends with woody biomasses (15 wt% biomass and 85 wt% coal). Previously, this model was validated with eleven (11) different solid fuels burning at a 100 kW down fired combustor, and this is the first scaleup study under industrially relevant conditions at MW TH.

WhatsApp: +86 18203695377The mill utilizes a 125 HP motor to grind or classify sizes down to a level where 97% pass through a 20 micron screen. The outlet particle size is controlled using an internal dynamic classifier, which recirculates coarser particles back to the grinding zone to achieve the appropriate grind and provide a tight particle size distribution.

This mill retrofit goes well beyond the improvements achievable with stationary classifier retrofits, especially when 80+%/200 fineness is required. Rotating classifier pressure drop is lower than that of stationary classifiers.
