Title:
AIR FEEDER
Document Type and Number:
Japanese Patent JPS5472524
Kind Code:
A
Abstract:
An arrangement for supplying air to a boiler-furnace whereby an axial flow fan being used as a source of primary air may selectively take suction air from the atmosphere or from the discharge side of a fan being used to provide secondary air to the boiler. This arrangement will provide an increased inlet pressure for the primary air fan to thereby achieve increased stability and high system pressure for low load operation, thereby permitting the effective use of an axial flow fan as a source of primary air when such usage would otherwise be unjustified.
