Economic analysis of pneumatic conveying system
In the design of pneumatic ash handling system, it is necessary to ensure that the expected conveying task can be completed. At the same time, the type and capacity of the equipment to be used, as well as the related problems, should be reasonably determined. In the design, not only the cost of equipment should be considered, but also the influence of material properties on quality, conveying capacity, conveying distance, conveying route and transportation should be considered comprehensively For example, for some materials, the conditions of various equipment are suitable for pneumatic conveying, but when pneumatic conveying cannot be adopted due to the material containing a large amount of moisture and adhesion, even if the cost of mechanical conveying equipment is high, mechanical conveying mode must be selected.
When the economy is reasonable, generally speaking, mechanical transportation is favorable for short distance transportation; on the contrary, for long-distance transportation, although pneumatic conveying system is unfavorable in terms of required power, it is often advantageous to adopt pneumatic conveying system in terms of equipment cost. The equipment cost, power required and operation cost vary greatly with the surrounding conditions, so it can not be compared generally. Meanwhile, it should be noted that with the different conditions of various platform supports and ancillary equipment, the variation range is also large. In a word, when designing the pneumatic ash handling system, the appropriate conveying system and corresponding equipment should be selected according to the specific conditions of the project and after comprehensive technical and economic comparison.
