Embodiment 1
[0036] see figure 1 , The tube plate cooling chamber structure of the high temperature fire tube waste heat boiler includes four parts: the cooling chamber tube plate, the flexible tube plate of the synthesis gas pipe, the synthesis gas pipe and the cooling water pipe. The cooling water pipe includes the cooling water inlet pipe and the central cooling water outlet pipe. The distance S1 between the central cooling water outlet pipe and the flexible tube sheet of the syngas is 5-30mm. The distance h between the tube sheet of the cooling chamber and the flexible tube sheet of the synthesis gas is 100-600 mm.
[0037] see figure 2 , there are 8 tube holes on the tube plate of the cooling chamber for the passage of the synthetic gas pipe, which are evenly distributed on the circumference of the radius R centered on the axis of the cooling chamber. The annular gap r1 between the tube sheet of the cooling chamber and the synthesis gas pipe, r1=5-20mm, serves as the outlet of the ...
