A double set of air-cooled slag discharge tubes is a slag pipe structure that uses the wind of the air chamber to cool the upper part of the slag pipe between the two sets of pipes(the structure is completely interchangeable with the old structure slag discharge pipes), and the material is heat-resistant and non-rust-resistant.(ZG4Cr26Ni4 Mn3NRe), This kind of slag pipe can solve the problems existing in the following conventional slag pipes:
1, due to the cooling of the wind in the middle of the two sets, the problem of coking at the top of the slag pipe can be completely solved. The top of the slag pipe is a fluidized dead angle. There is no heat transfer surface in the conventional slag pipe structure and it is very easy to focus.
2, because the cooling wind has the cooling and maintaining constant temperature effect on the welds of the cloth wind board and slag pipe, it solves the problem of welding seam cracking and dewelding due to the thermal deformation stress caused by the intermittent discharge of slag on the welds of the wind board and slag pipe.
3, because there is a relatively significant diameter change structure in the structure of a double set of air-cooled slag discharge pipes, it can ensure that there will be no slag spray and fire spray in a large number of conventional slag discharge, which improves the working safety of slag discharge workers.
4, because this structure slag discharge pipe uses a heat-resistant non-rust-resistant cast(ZG4Cr26Ni4 Mn3NRe) material, this material is better than 1Cr18Ni9Ti(used in the old structure) heat resistant stainless steel pipe. This structure is designed to have a wall thickness of 10-12 mm(the thickness of the old structure design is 5 mm), which is much higher in service life than the old structure slag discharge pipe, reducing the number of slag discharge pipe replacements. The number of boiler accidents and the maintenance of slag discharge pipe were reduced accordingly.
