• Coal CV ~24MJ kg • Brittle material • Mill inlet temp ~ 260-300 C • Outlet temp target 90 C Biomass Milling • 50t hr target throughput (giving similar heat input to coal) • Wood pellets are broken back to constituent particles • Further grinding is beneficial to combustion • Fibrous material • Mill inlet temp max ~ 170 C.

Coal Pulverizer Inerting And Fire Extinguishing System

Hot primary air for drying and coal transport enters the windbox plenum underneath the grinding table and flows upward through a swirl ring having multiple sloped nozzles surrounding the grinding table. The air mixes with and dries coal in the grinding zone and carries pulverized coal particles upward into a classifier. Fine.

Single Pass Air System With a single pass air system, air is drawn into the mill base, travels through the classifier, bag filter and fan and is then vented out to atmosphere. In addition to being dust free, the air swept grinding zone prevents over-grinding by the air stream lifting the particles of certain sizes out of the grinding zone.

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300 C. Inert kiln exhaust gases with oxygen content.

There is no clinker cooler baghouse or stack. Instead, some of the pre-heated air from the clinker cooler (tertiary air) provides combustion air to the precalciner. The rest is used in the in-line raw mill to dry the kiln feed materials. Therefore, all of the air from the clinker cooler eventually flows through the main baghouse and stack.

May 27, 2016 Hot air for drying coal can come from cooler exhaust (normal air) or preheater exhaust (low oxygen). The inlet temperature to the mill is con- trolled to maintain the outlet temperature as described above and dedusted in a cyclone. Tempering to about 370 C is effected by bleed- ing in cold air between cooler and cyclone.
