Recognition processing method for combustion efficiency of biomass combustion machine

The invention relates to the technical field of efficiency measurement, in particular to an identification processing method for combustion efficiency of a biomass combustion machine. The method comprises the steps that the air inlet speed, the spiral rotating speed, the space proportion and the heat value of the biomass burner are obtained; the air inlet speed sequence and the spiral rotating speed sequence form a first correlation coefficient sequence; acquiring a real-time operation performance set which corresponds to the current biomass burner and is constructed by the first correlation coefficient sequence and the heat value sequence; when the real-time operation performance set of the biomass burner does not belong to the normal performance set, calculating an abnormal risk value of the biomass burner; adjusting the real-time heat value according to the abnormal risk value to obtain an updated heat value; and judging whether the combustion efficiency of the biomass combustion machine is abnormal or not
