specific Embodiment approach 1
[0007] Specific implementation manner one: such as Figure 1~5 As shown, the biomass and coal combined gasification combustion circulating fluidized bed reactor of this embodiment includes a reactor vessel 1, a water-cooled wall 2, a connecting pipe 4, and two throttle valves 5. The fluidized bed reactor The device also includes three partitions 3, which are composed of a partition main body 3-1 and a baffle 3-2. The cross section of the baffle 3-2 is arc-shaped. -1 are vertically arranged on the bottom end of the reactor vessel 1, and the reactor vessel 1 is divided into three reaction zones, the three reaction zones are the first reaction zone 6, the second reaction zone 7 and the third reaction zone. 8. Two of the partition bodies 3-1 are on the same plane, and the other partition body 3-1 is arranged perpendicular to it, and the upper end surface of each partition body 3-1 is connected to the corresponding baffle 3-2 The longitudinal section of the three baffles 3-2 are fix...
specific Embodiment approach 5
[0011] Specific implementation manner five: such as figure 1 As shown, the bottom area of the first reaction zone 6 in this embodiment accounts for 35% to 45% of the bottom area of the reactor vessel 1. The other composition and connection relationship are the same as in the fourth embodiment.
[0012] Specific implementation manner six: such as figure 1 As shown, the bottom area of the first reaction zone 6 in this embodiment accounts for 40% of the bottom area of the reactor vessel 1. Other components and connection relationships are the same as those in the fifth embodiment.
specific Embodiment approach 7
[0013] Specific implementation manner seven: such as figure 1 As shown, the bottom area of the second reaction zone 7 in this embodiment accounts for 30%-50% of the bottom area of the reactor vessel 1. Other components and connection relationships are the same as those in the first, second, fourth, fifth or sixth embodiment.
