The invention relates to the technical field of decomposing furnaces, in particular to a calcium carbonate decomposing furnace which comprises a decomposing furnace body and further comprises a tertiary air pipe, a combustion chamber, a first discharging pipe, a first scattering box and a mixed combustion chamber. The combustion chamber is arranged on the decomposing furnace main body in a large volute shape in an overhead view, an opening in one end of the combustion chamber is horizontally arranged and is tangent to the decomposing furnace main body, the width size of the combustion chamber is gradually reduced from the opening to the inside, and the height is gradually reduced; the tertiary air pipe is in butt joint with an opening of the combustion chamber; the mixed combustion chamber is arranged above the combustion chamber and is communicated with the combustion chamber; the first scattering box is arranged at one end of the co-combustion chamber; the bottom of the first discharging pipe communicates with the first scattering box, and the first discharging pipe is obliquely arranged. And a first coal injection pipe is arranged on the first blanking pipe. The calcium carbonate raw material and the pulverized coal are flatly laid above the tertiary tuyere area, and the opening is intersected with the tertiary air plane, so that the heat exchange efficiency is improved.
本发明涉及分解炉技术领域，具体涉及一种碳酸钙分解炉，包括分解炉主体，还包括：三次风管、燃烧室、第一下料管、第一撒料箱和混燃室，其中：分解炉主体的下端具有锥形缩口；燃烧室俯视呈大涡壳状设置在分解炉主体上，其一端开口水平设置，且与分解炉主体相切，燃烧室的宽度尺寸从开口向内逐渐减小，且高度逐渐降低；三次风管与燃烧室的开口对接混燃室设置在燃烧室的上方，且与燃烧室相连通；第一撒料箱设置在混燃室的一端；第一下料管的底部与第一撒料箱连通，第一下料管倾斜设置；第一下料管上设有第一喷煤管。本发明让碳酸钙原料和煤粉平铺在三次风口区上方，开口处与三次风平面交会，提升了热交换效率。
