Abstract: A reversible, wear-resistant ash screw cooler section is provided with a carbon steel inner liner having a high chrome, high carbide overlay emplaced thereon to improve its wear and erosion resistance. To facilitate obtaining the maximum wear out of the section, the replaceable section is made symmetrical about its vertical and longitudinal centerline and provided with suitable compatible flanges and symmetrically placed cooling water hookups on the ends of the section to allow the section to be reversed, end for end, and reconnected to the ash screw cooler.

Abstract: A primary air exchange device for a burner of a pulverized fuel, such as coal, with burner including a supply line through which a primary air and pulverized fuel mixture is supplied. A separator having its inlet within the supply line 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. Additionally approximately 90% of the pulverized fuel passes the separator while only about 10% of the pulverized fuel enters the separator along with approximately one half the primary air. This air and small quantity of fuel mixture is delivered from the separator to a nozzle where it is discharged into a burner throat of a furnace. Hot air 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.
