Abstract

Experimental studies were carried out for determining the current volumetric concentration of oxygen in air using direct (gas analyzer) and indirect (based on meteorological data) methods. A metrological assessment of these methods was carried out (the uncertainty of the measured values of the volumetric oxygen concentration by the direct method is 0.104%, the indirect method is <0.03%), which confirmed the possibility of using the indirect method of determining the volumetric oxygen concentration to improve the accuracy of determining the thermal parameters of the operation of boiler plants. On the basis of the PBGM type burner with a developed fuel combustion control system, commissioning and operational tests of the NIISTU-5 boiler unit were carried out. The obtained results indicate the possibility of highly efficient using of obsolete boiler units by replacing the burner with the developed system. The use of a computerized system for monitoring the fuel combustion process allowed to maintain the nominal efficiency of the boiler under any modes of its operation by reducing heat loss with flue gases. An environmental analysis of the system’s efficiency showed the possibility of fuel combustion with the emission of harmful substances (CO and NOx) in the exhaust gases at a level not exceeding the standards of the European Union. Analysis of the effectiveness of the system showed that the return on investment is less than one heating season.
