The invention provides a method for determining the content of phenolic organic matters in tar residue and phenolic wastewater, which comprises the following steps: optimizing an MRM (Magnetic Resonance Modeling) method based on a GC-QQQ optimizer to obtain an optimized MRM method; detecting mixed standard solutions of phenol, o-methylphenol and p-methylphenol with different concentration gradients by using an optimized MRM method to obtain a linear regression equation corresponding to the characteristic ion flow peak area and the concentration of each compound, and taking the linear regression equation as a quantitative standard curve equation of each compound; the method comprises the following steps: extracting organic matters in a liquid phase and a solid content of coal tar and phenolic wastewater raw materials into an organic phase, and circularly washing the raw materials for multiple times by using an extraction solvent to obtain a to-be-detected organic phase; detecting a to-be-detected organic phase by using an optimized MRM method, and comparing and matching the quantitative ion pair and the qualitative ion pair with compounds in the standard solution to obtain a characteristic peak of the to-be-detected organic phase; and obtaining the content of each compound in the sample to be detected according to the peak area of the characteristic peak of each compound and the quantitative standard curve equation.

This invention discloses a co-firing biomass gas burner and method, belonging to the technical field of combustion equipment. The burner includes a central duct, an inner secondary duct, and an outer secondary duct, coaxially arranged from the inside out. A pulverized coal concentrator is installed inside the central duct, and its outlet end has a slitted blunt body structure with a central through-hole and an axial slit, used to form a graded pulverized coal gas flow. The biomass gas pipeline is equipped with a mechanical tar reduction structure based on temperature detection and flow rate regulation. Through the cooperation of the pulverized coal concentrator, the slitted blunt body, the secondary air swirl blades, and the guide plate, a series of primary and secondary recirculation zones are formed within the burner, achieving zoned mixing and graded combustion of pulverized coal and biomass gas. This invention solves the technical problems of incomplete co-firing, tar blockage, and low-NOx combustion in existing technologies, improving combustion efficiency, stable combustion performance, and reducing pollutant emissions.
