摘要: The invention relates to an annular shaft kiln for calcining granular material (G), in particular for calcining limestone or dolomite, comprising an upper shaft (20, 20') for preheating the granular material (G) and a main shaft (10, 10') arranged thereunder, with an axially arranged inner cylinder (30) for calcining and subsequently cooling the granular material. The annular shaft kiln according to the invention is characterized in that the upper shaft (20, 20') has a reduced inside diameter in comparison with the main shaft (10, 10').

摘要: The invention relates to a device for burning solid matter, especially for producing quicklime, dolomite lime or cement, said device comprising a rotary kiln (1) in which the combustion product (2) transported longways through the kiln (1) is burned by means of a combustion unit (1b), a cooling section (4) which is arranged downstream of the kiln (1) and in which a rising cooling air stream (4b, 4b*) is produced by means of at least one cooling fan in order to cool the burned combustion product (2*) transported along the bottom (4a) of the cooling section (4), the bottom (4a) of the cooling section (4) comprising openings for the cooling air stream (4b, 4b*), and a kiln hood (3) comprising a flume (3a) and connecting the outlet (1a) of the rotary kiln (1) to the cooling section (4). According to the invention, the cooling air stream (4d) flowing through the burnt combustion product (2*) - that leaves the kiln (1), passes through the flume (3a), and is deposited on the bottom (4a) of the cooling section (4) - rises into the kiln (1), via the flume (3a), and feeds the flame (1c) of the combustion unit (1b) as secondary air. The inventive device is characterised in that the flume (3a) contains means for separating the rising cooling air stream (4d) from the burnt combustion product (2*) that leaves the kiln (1) and is deposited on the bottom (4a) of the cooling section (4).

摘要: The invention relates to a device for burning solid matter, especially for producing quicklime, dolomite lime or cement, said device comprising a rotary kiln (1), and a cooling section (4) located downstream of said kiln (1). The inventive device is characterised in that a flume (3a) contains means for separating the rising cooling air stream (4d) from the burnt combustion product (2*) that leaves the kiln (1) and is deposited on the bottom (4a) of the cooling section (4). The flume (3a) in the kiln hood comprises at least one mobile wall (6) for controlling the flow course of the rising heated cooling air stream, said wall being located above the outlet (1a) of the rotary kiln.
