THERMAL ENGINEERING AND ENVIRONMENTAL STUDIES OF BURNERS OF THE START-UP AND PEAK BOILER HOUSE AND FURNACE FARM AT OIL REFINERY

This article presents the results of pilot studies aimed at improving the efficiency and environmental safety of an oil refinery's boiler and furnace fleet. The objective of the study was to inspect the technical condition of burner assemblies, measure harmful emissions, and develop measures to modernize existing equipment. The authors identified the main problems associated with operating injection burners (GEVK-500 and GGM-5 types) burning refinery gases of variable composition. Practical recommendations are offered, including a method for adjusting gas pressure without modifying the burner design and upgrading gas nozzles. Special attention is paid to the development and implementation of a new patented two-stage gas-oil burner design. This technical solution enables a two-stage air supply, which reduces NOx emissions by 40-50 %. The environmental passports developed by the authors provide prompt information for effective management and equipment replacement, thereby reducing the negative impact on the environment.
