PERFORMANCE OF FLAMMABILITY OF KEROSENE AND NOX EMISSION IN THE POROUS BURNER

The present study aims to develop the porous ceramic burner applicable to the Stirling engine, boilers and gas turbines using liquid fuels w ith the flammability in a large input load. As a liquid fuel, kerosene is supplied dropwise on the top surface of the porous ceramic plate a nd ignited on the bottom surface. The combustion behavior of the burne r is examined by measuring the profiles of temperature and composition of combustion gas along the centerline in the chamber. The promotion effect of combustion is examined experimentally by installing a wire n et at the chamber outlet. The boundary condition of the combustion cha nges substantially in the presence of the wire net. The behavior of NO x formation can be correlated by a function of the equilibrium NO conc entration at a maximum temperature in the burner. (C) 1998 Elsevier Sc ience Ltd.
