RESEARCH OF INFLUENCE OF STRUCTURAL FACTORS ON THE TECHNICAL IMPLEMENTATION OF THE EXPRESS CONTROL METHOD OF NATURAL GAS COMBUSTION

Abstract

The analysis of the known regulatory methods and technical solutions for the calculation and experimental method of determining the heat of combustion of natural gas is carried out. The necessity to determine the heat of combustion of wet natural gas by consumers at the place of work of gas-consuming equipment is substantiated. The technical solution for the implementation of the patented method for determining the heat of combustion of natural gas by the direct method of gas combustion temperature. The quantitatively estimated change in the relative error of determination of natural gas combustion heat from gas moisture and air humidity for the conditions of implementation of the proposed method of determining combustion heat for specific three gas samples with combustion heat of 7759 kcal/m³, 8145 kcal/m³ and 8538 kcal/m³. The regularities of change of relative error of determination of combustion heat from two components of humidity are established. The relative error of determining the heat of combustion of natural gas simultaneously from its humidity and humidity of the surrounding air is simulated. The influence of design factors that influence the technical implementation of the method of express control of the heat of combustion of natural gas is investigated. The presence of a significant temperature gradient along the surface of the thin plate and much less its value for the coarser plate was established. Dynamic characteristics of plate and thermocouple heating in the measurement of flame temperature are investigated.
