PURPOSE: A steam heating and spraying gas burner is provided to improve heating value because water gas shift rate of fuel is improved in combustion of the fuel by using a burner and a nozzle. CONSTITUTION: A steam heating and spraying gas burner comprises a water gas shift space(18), a water gas spraying nozzle(19), a fuel supply pipe(11), and a steam supply pipe(13). Steam and fuel is pressurized in the water gas shift space and is heated in the deep part of a furnace. Water-gaseous fuel is sprayed from a flow direction of combustion air and a reverse direction through the water gas spraying nozzle. In order to obtain maximum passage for the combustion air and to maintain heat insulation, the fuel supply pipe and the steam supply pipe are arranged in the center of the burner.
