Combustor and gas water heater

Abstract

The invention discloses a combustor and a gas water heater. The combustor comprises a shell, an air inlet assembly, a gas assembly, an atmospheric combustor and a gas injection pipe, and an air inlet chamber, a first combustion chamber and a second combustion chamber are formed in the shell; air is introduced into the air inlet assembly; gas is introduced into the gas assembly; the atmospheric combustor is used for igniting the mixed gas in the first combustion chamber and heating the temperature in the first combustion chamber to a preset temperature; and the gas injection pipe communicates with the second combustion chamber to inject the gas into the second combustion chamber, so that high-temperature air combustion is conducted in the second combustion chamber. The combustor with a high-temperature air combustion function and the gas water heater are provided.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201910992986.8 and the application name "Burner and Gas Water Heater" dated October 17, 2019, which is hereby incorporated by reference in its entirety. technical field

[0002] The invention relates to the technical field of high-temperature air combustion, in particular to a burner and a gas water heater. Background technique

[0003] High temperature air combustion (high temperature air combustion) is called "mild and deep low oxygen dilution combustion", referred to as soft combustion, which is a new type of combustion, also known as MILD combustion. The main characteristics of this combustion are: the chemical reaction mainly occurs in a high-temperature and low-oxygen environment, the temperature of the reactants is higher than its natural temperature, and the maximum temperature rise during the combustion process is lower than its natural temperature, and the oxyge...
