Open fire kiln for decomposing and calcining blocky lime outside kiln and lime calcining process thereof
The invention relates to an open-fire kiln for decomposing and calcining blocky lime outside the kiln. The open-fire kiln is characterized by comprising an outside-kiln body and a kiln body, the kiln outer body is arranged on the kiln body and comprises a fuel falling chamber, a kiln outer decomposition chamber, a heat conduction material separation grid, a material falling control device, a lime falling channel, a channel, a combustion and cooling chamber, a blower device and a discharging control device; meanwhile, the invention discloses a lime calcining process of the open-fire kiln for decomposing and calcining blocky lime outside the kiln. The device has the advantages that the decomposition chamber outside the kiln is arranged, so that preheating temperature rise heat absorption of limestone and a large amount of heat absorption during calcination decomposition are completed in the decomposition chamber outside the kiln; the decomposed materials are controllably and quantitatively fed into the combustion and cooling chamber through the blanking control device and are further burnt thoroughly, so that the temperature of the hearth of the combustion chamber is reduced by lime decomposition and heat absorption; in this way, various types of low-calorific-value fuels can be burnt, and the fuels can generate blast furnace temperature to successfully calcine lime; through open fire calcination, volatile matters can be fully combusted, and energy consumption is reduced.
本发明涉及一种窑外分解煅烧块状石灰的明火窑，特点是窑外体及窑体；所述窑外体设在窑体上，包括落燃料室、窑外分解室、导热隔料栅、落料控制装置、石灰落料通道、通道、燃烧及冷却室、鼓风装置及出料控制装置、燃烧及冷却室、鼓风装置及出料控制装置；同时公开了窑外分解煅烧块状石灰的明火窑的煅烧石灰工艺；其优点是：设置窑外分解室，使石灰石的预热升温吸热及锻烧分解时的大量吸热都在窑外分解室中完成；分解后的物料经落料控制装置可控地定量送入燃烧及冷却室再进一步烧透使燃烧室炉膛的温度少被石灰分解吸热而降低；这样可烧多种类型的低热值燃料，燃料能产生高炉温而成功煅烧石灰；明火煅烧，挥发份可充分燃烧，降低能耗。
