Abstract

The invention provides a combustor and a gas water heater. The combustor comprises a shell, a plurality of groups of burner bodies are arranged inside the shell, the shell is provided with an air supplementing air inlet, the air supplementing air inlet comprises a long opening and an auxiliary opening, the auxiliary opening is provided with a baffle plate, and the baffle plate is provided with a first state enabling the auxiliary opening to be sealed, a second state enabling the auxiliary opening to be partially opened and a third state enabling the auxiliary opening to be completely opened. According to the combustor and the gas water heater, the air inlet quantity of the air supplementing air inlet is controlled through the baffle plate, air supplementation is carried out according to the number and the position of the burner bodies in the opening state, it is guaranteed that the entering air accurately participates in mixed burning with fuel gas, the combustion efficiency is improved, and emission of carbon monoxide and nitride is reduced; and the baffle plate is rotated and adjusted by using a rotating shaft, a certain guiding effect is generated for the supplemented air, the mixing effect between the air and the fuel gas is improved, and then the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of domestic hot water equipment, in particular to a burner and a gas water heater. Background technique [0002] The safety and environmental protection of gas water heaters is an extremely important indicator. Gas water heaters on the market affect safety and environmental protection, mainly reflected in the use of segmented combustion when the water volume is small, but in segmented combustion, mainly by adjusting the air flow of the fan To adjust the supply ratio of gas and air, but only part of the fire row burns during staged combustion, and the size of the air inlet remains unchanged. As a result, no matter how the air volume of the fan is adjusted, some air will always pass through the unburned fire row area. It can be mixed with the burning gas to participate in the combustion. In order to control the total flow, it is easy to cause insufficient mixing of gas and air; in the process of circulation, i...
