Combustion of Low Caloric Natural Gases at Domestic and Industrial Boilers

摘要

Combustion of low caloric natural gases (LCNG) containing up to 66 per cent of inert gases in domestic and industrial boilers was investigated. The calculations of paraemters of laminar flame of such gases by procesure RUN-1DL with GRI 177 steps elementary rections will be presented. The influence of molar composition of natural gas on the range of capacity of burners and emissions of NOx and CO will be also presented. The data obtained from calculations and experiment led to the construction of special gas burners for industrial gas boiler supplied with extremely low caloric natural gas. The results of emission of pollutants obtained allow seeing of such gases as useful fuels.
