Abstract
A Yankee hood is disclosed for use in drying wet paper webs. The Yankee will provide a manufacturer to operate at supply temperatures above 1000.degree. F. at lower total energy costs and at increased production. All major components, supply fans, flow concentrator, air flow equalization plenum and gas burner are consolidated and are mounted directly on the device to eliminate the need for additional space requirements. The hood assembly includes an internal high impingement air system which is supported on a floating structural support member. The nozzle impingement system which incorporates a plurality of nozzle boxes will cover approximately a 240.degree. wrap of a typical Yankee cylinder which will be decoupled from its main support end plate members to allow for increases in cross-machine expansion. The support structure for the externally located direct drive motor is designed to eliminate hood vibrations and operate above the natural building frequency.
