Контроль процесса сжигания топлива в котлоагрегатах малой и средней мощности с использованием сенсоров кислорода

Abstract

Boiler’s technical condition which are using in communal and industrial power engineering is being analyzed. The method of improving the accuracy of the excess air ratio which based on present level of oxygen’s concentration in the air is offered. The structure of fuel combustion monitoring and directing system is developed. The structure based on fluent speed regulation of ventilator ‘s engine on signals of oxygen sensors in the exhaust gases are elaborated. The results of experimental research of developed system based on boiler NIISTU-5 are showed.
