Abstract

The invention relates to a sectional type combustion device and a gas water heater. When mixed gas is introduced into a first gas inlet channel, the mixed gas flows into a third mixing cavity under the action of a flow dividing cavity and finally flows out of second fire holes of a second main body. When the mixed gas is introduced into second gas inlet channels, the mixed gas flows into a second mixing cavity, and then flows into a first mixing cavity from first gas outlet holes in a gas distributing body; and finally, the mixed gas flows out of first fire holes in a first main body. Thus, the mixed gas flows out from different height positions, then the requirements of users for combustion under different loads are effectively met, and sectional type combustion of the combustion device is realized. According to the sectional type combustion device, in the gas inlet process, the second mixing cavity is formed in the gas distributing body through a first flow dividing piece, the circulation path of the mixed gas is effectively prolonged, then gas and air are fully mixed, the mixing uniformity of the gas is improved, and the sectional combustion characteristic can be improved.

Description

technical field [0001] The invention relates to the technical field of gas combustion, in particular to a segmented combustion device and a gas water heater. Background technique [0002] A burner is a device that burns a mixture of gas and air. According to different combustion forms, it can be divided into full premixed combustion device and atmospheric combustion device. [0003] In order to increase the heat load adjustment ratio, the existing atmospheric burner is designed as a two-layer burner body structure connected up and down. During the intake process, relying on the intake structure, the gas is divided into two streams, so that they flow independently into the upper and lower burner bodies to achieve different load combustion. However, limited by the intake structure design, there is still room for improvement in the combustion characteristics and overall volume design of the burner. Contents of the invention [0004] The first technical problem to be solved...
