【実用新案登録請求の範囲】[Scope of utility model registration request] 高炉の送風支管への挿入部分の管内径が羽口からの逆火
の発生を防止する流速以上を得られる小径となっており
、かつ、その他の部分が微粉炭の沈降を防止する流速を
得られる大きな管内径となっていることを特徴とする、
微粉炭吹込み用配管。The inner diameter of the part inserted into the blast furnace's blast furnace branch pipe is small enough to obtain a flow velocity that is at least sufficient to prevent backfire from occurring from the tuyere, and the other part has a flow velocity that is sufficient to prevent pulverized coal from settling. It is characterized by a large inner diameter of the pipe.
