Problems solved by technology

However, because the air volume of the secondary air is much larger than the air volume of the primary air, the mixing effect of the secondary air and the gas is not good, so that the combustion of the gas is insufficient and the combustion flame is unstable.

Abstract

The invention discloses a burner for a gas water heater and the gas water heater provided with the same. The burner for the gas water heater comprises a body and an enhanced mixing and preheating structure. The body is provided with a gas inlet and a gas outlet. The gas outlet comprises at least one gas outlet hole. The enhanced mixing and preheating structure is arranged on the side, far away from the center of the body, of the gas outlet. The enhanced mixing and preheating structure is arranged to make gas flow sprayed from the gas outlet and air surrounding the gas outlet mixed and preheat the gas flow by smoke generated by combustion of the burner. According to the burner for the gas water heater, the enhanced mixing and preheating structure is arranged at the gas outlet, gas can easily entrain surrounding air like secondary air, gas and secondary air can be fully mixed easily, gas can easily entrain smoke generated due to combustion to preheat mixed gas of gas and air or gas flow before mixing, so energy can be fully used, and energy consumption of the burner is reduced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a burner for a gas water heater and a gas water heater with the burner. Background technique [0002] In related technologies, gas water heaters, such as blower gas water heaters, are usually fed by a blower to mix air and gas in the combustion chamber for combustion and heat release, and then heat exchange with cold water in the heat exchange chamber to heat to hot water to meet user needs. According to the difference of mixing time with gas, the air is divided into primary air and secondary air. The primary air is usually injected into the burner by injection gas to achieve premixing of gas and air, and the secondary air is non-premixed combustion with the gas at the outlet of the burner. However, since the air volume of the secondary air is much larger than that of the primary air, the mixing effect of the secondary air and the gas is not good, so that the combustion of...
