FEATURES OF THE USE OF REFINERY GASES FOR HEATING FURNACES AND BOILERS

Described experience of using refinery gases based on the research and development done by members of the Gas Institute of NAS of Ukraine, as well as other authors at oil refineries. The composition of such gases includes hydrocarbons of the paraffin СН4, С2Н6, С3Н8, С4Н10, etc., the unsaturated hydrocarbons С2Н4, С3Н6, С4Н8 and others, in addition they contain a considerable amount of H2 and of small quantities of H2S. Shows the fundamental shortcomings of the designs of gas-burning devices intended for operation on natural gas and propane-butane mixture, used for combustion of refinery gases. This is caused by the high content of hydrogen in these gases, which has higher speed of flame propagation, and hydrogen sulfide, decomposing at relatively low temperatures. Are considered peculiarities of application of refining gases, the developed technology of combustion in furnaces and boilers, as well as the design of burners. Also are considered some safety measures when burning gases of oil refining, which differ from these when using natural gas. Bibl. 21, Fig. 2, Tab. 2.
