燃气式回转炉的炉膛结构
摘要：
本发明涉及一种燃气式回转炉的炉膛结构，主要解决现有技术中现有燃气式回转炉加热效率低的问题。本发明通过采用一种燃气式回转炉的炉膛结构，炉膛结构环绕设置于回转炉筒体的外侧；所述炉膛结构包括下炉膛、上炉膛、燃烧气进口、热烟气出口、迷宫式流道；其中，下炉膛设置于炉筒底部，燃烧气进口设置于下炉膛，上炉膛设置于炉筒上部，热烟气出口设置于上炉膛，下炉膛和上炉膛相扣合连接形成内部迷宫式流道结构的技术方案较好地解决了上述问题，可用于燃气式回转炉中。
摘要（英）：

The invention relates to a hearth structure for a gas rotary furnace and mainly solves the problem of low heating efficiency of a conventional gas rotary furnace in the prior art. The hearth structure for the gas rotary furnace is arranged on the outer side of the rotary furnace barrel in a surrounding manner, and comprises a lower hearth, an upper hearth, combustion gas inlets, a hot flue gas outlet and labyrinth channels, wherein the lower hearth is arranged at the bottom of a furnace barrel; the combustion gas inlets are formed in the lower hearth; the upper hearth is arranged at the upper part of the furnace barrel; the hot flue gas outlet is formed in the upper hearth; and the lower hearth and the upper hearth are fastened and connected to form an internal labyrinth channel structure. By adoption of the technical scheme, the problem is better solved, and the hearth structure can be used in the gas rotary furnace.
