A coal feed and milling assembly for a furnace, said 2 sembly comprising a generally vertical duct, means to deliver coal and hot gas to said duct adjacent an upper portion thereof, a beater wheel mill, a duct extending from said beater wheel mill to duct mill coal thereform to said furnace, and wherein said beater wheel mill includes a beater
The beater wheel mills built by ALSTOM Power Stuttgart are designed for maximum productivity. In nearly all major atmospheric, -lignite-fired steam power plants, the crude lignite is dried and pulverised in ALSTOM beater wheel mills. The beater wheel mill sucks hot flue gases from the cumbustion chamber through the flue gas pipe to dry the coal
These beater wheel mills are used to pulverise the crude lignite needed to generate steam. Hot flue gas is sucked into the beater wheel mill to dry the coal. While the coal is being pulverised, the coal dust is mixed with the flue gas, resulting in a high drying efficiency. The lignite/flue gas mixture is blown to the pulverised coal burner
Mill type Beater wheel mill Vertical roller mill Fineness of pulverized coal 40-50% of a 200 mesh pass (estimation) 70-80% of a 200 mesh pass Features ・Frequent maintenance of the high temperature gas system ・Poor applicability to low-rank coals with low grindability, while there are
The maximum coal throughput per mill is 142.5 t/h. Beater wheel mills with overhung shafts are arranged evenly around the steam generator in order to supply the burners of the tangential firing system in the most direct possible way.
Each coal mill consists of the following subassemblies: a) The slide-gate b) Movable mill inlet doors c) Mill body d) Box-type classifier e) Connection element between mill body and dust piping f) Hot gas recirculation duct from connection element to mill inlet doors g) Beater wheel h) Device for assembly and disassembly of beater wheel and
The beater wheel mill sucks hot flue gases from the cumbustion chamber through the flue gas pipe to dry the coal and blows the lignite/gas mixture through the pulverised coal pipes to the pulverised coal burner and to the combustion chamber.

The biggest challenge is to measure the hot flue gas flow into the beater wheel mill (see Figure 3). This recirculation gas is usually around 900°C and carries the bulk of the drying energy for the coal. On top of that this gas only contains 2% of O2 which makes it pivotal in keeping the mill inert.
Beater Mill or Fan Mill. TYPES OF MILL Tube or ball mills: These are high-speed impact machines that use beater wheels to crush the coal. Ball & Tube Mills. Tube mills: The tube mills are low-speed machines that capacity. At feed rates below 25% capacity, any momentary interruption of coal feed will allow the pulverizer to empty.

Comminution in the Cross Beater Mill takes place through impact, friction and shearing forces. The feeding funnel guides the grinding material directly into the centre of the grinding chamber, where it is comminuted between the cross beater and the teeth of the grinding insert. The selected bottom sieve determines the final fineness.
Pulverized coal goes from the pulverized coal hopper to receiving hopper and through the dosing machine cover openings enters the cells of the feeding wheel, that feeds pulverized coal into the metering wheel, from which the pulverized coal comes out in the distributing branch pipe and then into the pulverized-coal pipe.
Rolling Bearings in ALSTOM Beater Wheel Mills. steam power plants, the crude lignite is dried and pulverised in ALSTOM beater wheel mills. The beater wheel mill sucks hot flue gases from the cumbustion chamber through the flue gas pipe to dry the coal and blows the lignite/gas mixture through the pulverised coal pipes to the pulverised coal burner and to the combustion chamber.
