摘要：
本实用新型涉及自身返碱煅烧炉的环形管汽室循环加热系统，包括设在进汽轴中心的进汽管、设在进汽轴内壁与进汽管外壁之间的排水道，其特征在于：第一环形管汽室与进汽轴的上部连通；第二环形管汽室与进汽轴的中部连通；第三环形管汽室与进汽轴的下部连通；第四加热管的一端与第三环形管汽室连通，第三加热管的一端与第二环形管汽室连通；第二加热管的一端与第一环形管汽室连通；第一加热管的一端与第一环形管汽室连通。本实用新型和现有技术相比具有以下优点：蒸汽消耗大幅降低，吨碱汽耗为1.25-1.35吨；传热强度提高，产能提高15-25％。
摘要（英）：

The utility model relates to an annular tube steam chamber circular heating system of a self return soda ash steam calciner, comprising a steam inlet tube arranged in the center of a steam inlet shaft and a drain channel arranged between the inner wall of the steam inlet shaft and the outer wall of the steam inlet tube. The annular tube steam chamber circular heating system is characterized in that a first annular tube steam chamber is communicated with the upper part of the steam inlet shaft; a second annular tube steam chamber is communicated with the middle part of the steam inlet shaft; a third annular tube steam chamber is communicated with the lower part of the steam inlet shaft; one end of a fourth heating tube is communicated with the third annular tube steam chamber, and one end of a third heating tube is communicated with the second annular tube steam chamber; one end of a second heating tube is communicated with the first annular tube steam chamber; and one end of a first heating tube is communicated with the first annular tube steam chamber. Compared with the prior art, the utility model has the advantages that the steam consumption is greatly reduced, the gas consumption of per soda ash is 1.25-1.35 tons; the heat transfer strength is improved, and the production capacity is improved by 15-25 percent.
