PROBLEM TO BE SOLVED: To provide a burner for combustion capable of burning solid fuel and stabilized in accordance with a boiler load of wide range, and to provide the combustion device equipped with the burner. SOLUTION: A fuel density difference forming apparatus 201 is installed ion the direction of the sectional surface of the nozzle 206 at a part near a burner nozzle 206 for injecting fuel in a fuel supplying flow passage, while a nozzle 204 for increasing the density of fuel injected out of the burner nozzle 206 for injecting a specified fuel and, further, supplying air to the burner nozzle 206 for injecting the fuel high in the fuel density of the same is provided. The igniting property of the fuel at the outlet port of the burner nozzle 206 for injecting mixed fluid of a high fuel density is improved. Therefore, even a fuel comparatively inferior in the igniting property such as lignite or the like is ignited surely and a stabilized combustion property can be obtained.
