Burner and fuel gas hot water equipment adopting same

Abstract

The invention provides a burner which comprises at least two burner units, a second fuel-air mixing cavity as well as at least one fuel-air mixture distributing port, wherein each burner unit comprises a plurality of fire holes which are arranged in a lengthwise manner and a first fuel-air mixing cavity, and each first fuel-air mixing cavity is used for generating and transferring a first fuel-air mixture to the fire holes; at least two burner units are arranged side by side along a transverse direction and a gap is formed between the upper parts of the burner units, and the second fuel-air mixing cavity is used for generating a second fuel-air mixture; and at least one fuel-air mixture distributing port is arranged independently relative to at least two burner units and is communicated with gas in the second fuel-air mixing cavity so as to distribute the second fuel-air mixture to a gap between at least two burner units. Through the arrangement, the discharge of nitrogen oxide is effectively reduced and simultaneously the good burning effect is ensured, and the reconstruction of the fire discharge piece of the existing burner is reduced as much as possible.

Description

technical field [0001] The invention belongs to the field of combustion equipment, and in particular relates to a burner and gas hot water equipment using the burner. Background technique [0002] Gas hot water equipment, such as a gas water heater or a gas boiler, is usually provided with a burner, a heat exchanger, and a combustion chamber for accommodating the burner and the heat exchanger. The burner often includes several fire baffles arranged side by side, and each fire baffle has a gas-air mixing channel in which the gas and air can be mixed and delivered to the fire hole at the top of the fire baffle to burn in the combustion chamber and generate Heat, the generated heat can heat the water in the heat exchanger, so that the heated water can be used for drinking, bathing, or heating. [0003] During the combustion process, the burner produces exhaust gas, which is released into the atmosphere. Exhaust gas usually contains components that have an impact on the human ...

AI Technical Summary

Problems solved by technology

However, the burners with these new structures all need to carry out relatively large modifications to the fire fins in the existing burners, and in order to ensure a good combustion effect, the structure, size, or arrangement of the original fire fins have been carefully It is obtained through calculation, a series of experiments, and long-term manufacturing and use experience. Therefore, although the modified fire radiator can reduce the emission of nitrogen oxides to a certain extent, it may not be able to ensure the original combustion effect.
