| abstract | A double-walled pipe is used as a lance (4) for blowing in a fuel through a tuyere (3), whereby pulverized coal is blown in from the inner pipe (21) of the double-walled lance (4), and oxygen is blown in from the outer pipe (22) of the double-walled lance (4). Notches (23) are provided on the blowing-side tip section of the inner pipe (21) of the double-walled lance (4), and the oxygen concentration of a gas that comprises the pulverized coal carrier gas and the gas which is blown in from the outer pipe is set to 35 vol% or higher. Thus, the burning temperature can be increased even during a high-pulverized-coal-ratio operation at a volatile pulverized coal content of 25 mass% or less and a pulverized coal ratio of 150 kg/t or higher. Consequently, emission of CO |
