A QUAD SECTOR REGENERATIVE AIRPREHEATER FOR CIRCULATING FLUIDIZED BED COMBUSTION BOILERS

摘要

A quad sector regenerative Airpreheater for circulating fluidised bed combustion boiler comprises one gas sector (01), first secondary Air sector (02), one primary air sector (03) and second sec©ndary air sector (04) compartmented by sector plates; a cylindrical rotor (05) driven by the rotor drive (06) and surrounded by the rotor housing (07) and constructed between the cold end connecting plate (08) at one end and hot end connecting plate (09) at the other end; a support bearing (10) at the bottom and a guide bearing (11) at the top supports the rotor (05); characterized in that the primary air sector (03) is sandwiched on either side by the "secondary air sectors (02) and (04) minimizing air leakage to the gas side.
