Burner for a heater

Abstract

Disclosed is a burner for a heater. The burner includes a shell and an ejector assembly. The shell is provided with a circumferential surface, a gas chamber, a plurality of flame guide channels and an air intake. One end of each flame guide channel is communicated with the gas chamber, and other end of each flame guide channel intersects the circumferential surface. An extension direction of each flame guide channel is configured to form a non-perpendicular angle relative to the circumferential surface. The air intake is communicated with the gas chamber. The ejector assembly is detachably connected to the air intake, and is provided with an air passage hole communicated with the air intake.
