[0003] At present, the design of the biogas burner is only based on experience. When designing the biogas burner, the influence of the design parameters such as the excess air coefficient and the swirl angle of the biogas burner on the operating efficiency of the biogas boiler is not considered, which may cause biogas The exhaust smoke loss of the boiler is extremely high, which may cause part of the biogas to not be fully burned and cause heat loss, thereby reducing the operating efficiency of the biogas boiler

The invention discloses a method and device for determining design parameters of a biogas combustor in a biogas boiler. The method comprises the steps: determining the biogas consumption of biogas needing to be combusted by the biogas boiler under the rated load; determining initial design parameters of the biogas combustor, wherein the initial design parameters comprise an initial excess air coefficient and an initial rotational flow angle; determining at least two candidate coefficients according to a preset coefficient step length and the initial excess air coefficient; for each candidate coefficient, calculating a first section average temperature of a hearth outlet of the biogas combustor according to the biogas consumption, the candidate coefficient and the initial rotational flow angle; and determining the candidate coefficient corresponding to the minimum average temperature of the first section as the optimal excess air coefficient of the biogas combustor. By means of the technical scheme, biogas can be combusted more sufficiently in the biogas combustor to reduce heat loss, and therefore the operation efficiency of the biogas boiler is improved.
Description
technical field [0001] The invention relates to the field of energy, in particular to a method and a device for determining design parameters of a biogas burner in a biogas boiler. Background technique [0002] The biogas boiler burns biogas as fuel, providing heat while realizing the effective use of waste resources. The biogas burner, as the combustion device used to burn biogas in the biogas boiler, can directly affect the operating efficiency of the biogas boiler. [0003] At present, the design of the biogas burner is only based on experience. When designing the biogas burner, the influence of the design parameters such as the excess air coefficient and the swirl angle of the biogas burner on the operating efficiency of the biogas boiler is not considered, which may cause biogas The exhaust smoke loss of the boiler is extremely high, which may cause part of the biogas to not be fully burned and cause heat loss, thereby reducing the operating efficiency of the biogas bo...
