THE SYSTEM OF AUTOMATIC COMBUSTION CONTROL IN GAS-BURNING PLANTS BY CORRECTIVE PARAMETER

Abstract

The wide application of gaseous fuels in technology and energy, its high cost, pose the task of improving the quality of its use. The task of automation of technological processes of thermal units heated by natural gas is to increase the safety of operation and the efficiency of their operation. This problem is especially acute in conditions of continuous operation of thermal units, when the state of the environment varies from day to day and from summer to winter. The temperature of the air for combustion, its humidity, the heat of combustion of the gas and the atmospheric pressure fluctuate particularly sharply. In these conditions, when putting into operation the heat unit, it is necessary to set such tinctures that, in the event of unfavorable external conditions, there always was enough oxygen to completelyburn the gas. This can be achieved by increasing the efficiency of the automatic control system of the ratio of the combustion components and the temperature parameters of the unit, according to the optimal regime for each particular technological process. To achieve this goal, we used the results of research into the chemical processes of interaction of combustion products using means for measuring the electrical parameters of a flame based on physical methods of ionization control of the combustion process. The established features and obtained results made it possible to develop a device for monitoring the ionization properties of the combustion process, on their basis, automatic control systems of burners for industrial heat x aggregates.
