Primary air-fuel mixture dividing device for a pulverized-coal burner
A primary air-fuel mixture dividing device for a burner of a pulverized fuel, such as coal, including a supply line (24) through which a primary air and pulverized fuel mixture is supplied. A separator (30) having its inlet within the supply line (24) is dimensioned to receive and remove approximate...

| description | A primary air-fuel mixture dividing device for a burner of a pulverized fuel, such as coal, including a supply line (24) through which a primary air and pulverized fuel mixture is supplied. A separator (30) having its inlet within the supply line (24) is dimensioned to receive and remove approximately one half of the primary air while the remaining half of the primary air moves past the separator (30). Additionally approximately 90% of the pulverized fuel passes the separator (30) while only about 10% of the pulverized fuel enters the separator (30) along with approximately one half the primary air.This air and a small quantity of fuel mixture is delivered from the separator to a nozzle (38) where it is discharged into a burner throat (14) of a furnace. Hot air (40,44) is injected into the remaining mixture of half the primary air plus the large percentage of pulverized fuel to heat this fuel before it is injected into the furnace for ignition. |
