Title:
PREMIX BURNER FOR HEAT GENERATOR
Document Type and Number:
Japanese Patent JPH09184605
Kind Code:
A
Abstract:

To stabilize a flame, improve a combustion efficiency and reduce the exhaust of a toxic material by shifting upstream a fuel nozzle relative to a conical end part generated by the part member of a premix burner.

A fuel nozzle 103 is retracted upstream relative to an starting end part 125 conical in cross-section of flow, so that the opening 104 of the fuel nozzle 103 is located within a range between peripheral walls 101a and 102a fixed to a head side. A fuel spray 105 enters a range covered with a main current of combustion air entering the inner chamber 114 of a premix burner owing to the retraction and is decomposed into liquid drops. The entry of fuel air 115 to the fuel spray 105 improves the quality of mixture. A radially arranged opening 124 is provided in a range on the plane of the fuel spray opening 104 so that a flushing air is supplied. The fuel spray 105 improves an air mass flow passing through the opening 124 as a fuel injection pump and suppresses the flash back of a flame.
