[0016] Example 1
[0017] The present invention is a regenerative double-chamber lime kiln such as figure 1 As shown, it includes a feeding system, a discharging system, a combustion system, an air supply system, an exhaust gas discharge system, and two kiln bodies 8a and 8b arranged side by side. The cross section of the kiln body is circular. The two kiln bodies are respectively provided with a feed inlet 1, a preheating zone 9, a calcining zone 10, a high-temperature calcining zone 11, a cooling zone 6 and a discharge opening 7. The upper part of the cooling zone is provided with an annular channel 12 to communicate with each other. Connected through an annular channel. The upper part of the preheating zone is provided with a gas gathering device 2, which passes in combustion air during the calcination stage and exhausts exhaust gas during the heat storage stage. The inlet of the gas collecting device of the kiln body (8a, 8b) is respectively connected with the blower and the...
