Title:
INDUSTRIAL FLUID FUEL BURNER
Document Type and Number:
Japanese Patent JPS6149910
Kind Code:
A
Abstract:
A burner for gaseous or liquid fuel for heating furnaces includes a ceramic combustion chamber (20) for incomplete combustion of the fuel with primary air from which hot gases exit at high velocity through a constricted outlet (24). The combustion chamber is surrounded by a chamber (42) for the preheated remainder air necessary to complete combustion. Out of this chamber high velocity jets of air issue through nozzle openings encircling the combustion chamber outlet. Energy is saved and simple construction maintained by providing a tubular heat recuperator (4, 7, 9) rearwardly of the combustion chamber in which a cylindrical wall of temperature resistant steel passes to separate the recuperator into two annular chambers (10,11) and extends forward over a large part of the axial length of the combustion chamber so as to form an outer boundary of the remainder air chamber. The forward extension of the cylindrical wall (9) has an inturned rim constituting the ring-shaped nozzle carrier (33) in which the nozzle openings for the remainder air jets are provided. The combustion chamber is clamped between its spring-loaded fuel pipe (16) and the nozzle carrying rim (33) of the cylindrical wall (9).
