Are there any design specifications for the ash discharge pipelines in cement kilns?
Thread Content
1. Wear issue of the ash discharge pipe: The ash discharge pipe in the cement production line is 12 meters long and makes an angle of 60 degrees with the horizontal plane. Could wear be excessive? Is it acceptable to use it in this condition? 2. Buffering device for the ash discharge pipe: At what drop height in the ash discharge pipeline is it necessary to install a weight-driven flap valve in order to reduce the impact force during descent? 3. For cement kilns, which have many inclined ash discharge pipes (commonly known as chutes), are there any design specifications? It seems that no such standard can be found
It seems that there are no design specifications for pipelines in this area; it’s similar to the case with low-pressure systems, where non-standard, large-sized welded structures used in process engineering have no applicable specifications. Specifications do exist for pressure pipelines, pressure vessels, steel structures, and boilers. But for those that fall outside these categories, yet have similar or identical structural forms, no specifications can be found
1. Wear issue of the ash discharge pipe: The ash slide pipe in the cement line is 12 meters long and makes an angle of 60 degrees with the horizontal plane. Could the wear be too severe? Is it acceptable to allow this situation? Theoretically, any angle is possible; in case of wear, the pipe wall can be thickened, and for larger pipes, wear-resistant ceramic or manganese steel plates can be used as lining inside the tank. 2. Ash discharge pipe buffer device: At what drop in height of the ash discharge pipeline is it necessary to consider installing a weight-type flap valve in order to reduce the impact force during discharge? The main function of a weight-type flap valve is not buffering, but rather preventing air from leaking in and allowing the material to accumulate to a certain level before it is released all at once. 3. For cement kilns, which have many inclined ash discharge pipes (commonly known as chutes), are there any design specifications? It seems that no such standard can be found. First, let’s ask: what kind of kiln is a cement kiln? The common terms in the building materials industry are raw material mill, cement mill, and rotary kiln. A rotary kiln is used to burn clinker; the clinker, along with supplementary materials, must be ground in a cement mill before it can become cement. It’s best to look at a picture.
We are engaged in waste heat power generation at the kiln inlet and outlet – are there no calculation methods or quantitative indicators for the aspects mentioned earlier?
In China, many products with non-standard designs currently lack relevant standards
