Burner, burning heating method and burning heating equipment

Abstract

The invention relates to a burner, a burning heating method and burning heating equipment. The burner comprises a distributor chamber and gas mixing pipes, wherein the distributor chamber is provided with a cavity, and a fuel gas inlet is arranged on the distributor chamber; the inlet ends of the gas mixing pipes are communicated with the cavity of the distributor chamber so as to obtain fuel gas; the side wall of each gas mixing pipe is provided with at least one gas inlet hole used for absorbing combustion improver to be mixed with the fuel gas; and the outlet ends of the gas mixing pipes are used for providing mixing gas of the fuel gas and the combustion improver for burning. The burning heating method comprises the steps of distributing and leading the fuel gas into more than one gas mixing pipe; leading the combustion improver into the gas mixing pipes and mixing the combustion improver and the fuel gas in the gas mixing pipes through a set process to form the mixing gas; and enabling the mixing gas to flow out of the gas mixing pipes for burning. The burning heating equipment adopts the burner of the invention. The technical scheme provided by the invention improves the mixing effect of the fuel gas and air in the mode of burning after mixing, thereby improving the thermal efficiency and reducing the energy consumption and the environmental pollution.

Description

technical field [0001] The present invention relates to a burner, a combustion heating method, and combustion heating equipment, in particular to a burner used as a combustion head for combustion heating equipment, and to a combustion heating method performed by the burner, as well as a burner using the burner A variety of combustion heating equipment such as gas stoves, boilers and water heaters. Background technique [0002] Existing various combustion heating equipment, such as Chinese cooking gas stoves, stew gas stoves, civil gas stoves, small and medium-sized gas boilers and civil gas water heaters on the market, all need to use burners to connect to the gas source for heating. Burn to heat. These burners are also commonly referred to as burners or burners. Existing burner mainly contains two classes, and a class is the burner of combustion-supporting natural ventilation, and another kind is the burner of combustion-supporting of fan forced ventilation.

AI Technical Summary

Problems solved by technology

Because this type of burner adopts open combustion to supplement air, its common defects are: because it burns while mixing, the mixing effect of air and gas is not good, and it will start to burn when the mixing is uneven, resulting in a flame front. If the air-fuel ratio is too large, the combustion calorific value is not high, and the air-fuel ratio behind the flame front is too small, so that the combustion of the gas is incomplete; open combustion forms natural convection heat transfer with the atmosphere, and most of the heat released by combustion follows the natural The circulating cold air spreads outward, so a lot of heat energy is wasted, and the ineffective power consumption is more energy efficient

Because the forced ventilation of the fan is used for mixing, the following defects generally exist in this type of burner: 1) The air flow of the forced ventilation of the fan is relatively fast, and the gas flow follows the high-speed air flow in the burning disc of the burner, and it burns while mixing. Insufficient, resulting in insufficient combustion of gas; 2) The fan will generate forced convection heat transfer, which speeds up the heat diffusion, wastes a lot of heat energy, and has more ineffective power consumption; 3) The small fire is easily blown out by the fan when switching between large and small fires. Affect work efficiency; 4) The operation of the fan consumes electric energy, and the noise pollution of the fan operation is very serious

Therefore, there is no burner technical solution to solve the problem of low thermal efficiency in the prior art
