The invention relates to a double-hearth kiln which comprises two kiln bodies, a feeding system, an exhaust emission system, a fuel supply system, a discharging system and a control system. The kiln body is formed by rebuilding a beam type lime kiln or a common shaft kiln body. A preheating zone, a calcining zone and a cooling zone are arranged in the kiln body, and the calcining zone is provided with at least one plug-in burner. And a flue gas channel opening is formed between the calcining zone and the cooling zone of the kiln body and is formed in the corresponding outer walls of the two kiln bodies. And the flue gas ports of the two kiln bodies are connected together through a flue gas channel. The flue gas channel is inserted into the two kiln bodies, 2-10 supporting beams are arranged on the upper portion of the portion, inserted into the kiln bodies, of the flue gas channel, ridge type structures are arranged on the upper portions of the supporting beams, and the included angle of the ridge type structures ranges from 120 degrees to 150 degrees. The flue gas channel is arranged in the beam type lime kiln or the common shaft kiln, the two kiln bodies are connected together through the flue gas channel, and the supporting beam and the ridge type structure are additionally arranged on the part, inserted into the kiln body, of the flue gas channel, so that the safety of the part, connected with the kiln body, of the flue gas channel is improved, and long-period safe operation of the double-chamber kiln reconstructed from the beam type kiln is facilitated.
本发明涉及一种双膛窑，包括两个窑体、供料系统、废气排放系统、燃料供给系统、出料系统和控制系统。窑体由梁式石灰窑或普通竖窑的窑体改建而成。窑体内包括预热带、煅烧带和冷却带，煅烧带设有至少一根插入式烧嘴。窑体的煅烧带与冷却带之间设有烟气道口，烟气道口设置在两个窑体相对应的外壁。两个窑体的烟气道口通过烟气通道连接在一起。烟气通道插入两个窑体内部，烟气通道插入窑体部分的上部设有2‑10根支撑梁，支撑梁的上部设有脊式结构，脊式结构的夹角为120‑150°。本发明在梁式石灰窑或普通竖窑设置烟气通道，通过烟气通道将两个窑体连接在一起，通过在烟气通道插入窑体部分加设支撑梁和脊式结构，提高了烟气通道与窑体连接部分的安全性，有利于梁式窑改建的双膛窑的长周期安全运行。
