When designing a pneumatic ash removal system, the first step is to ensure that the expected conveying task can be completed. At the same time, it is necessary to reasonably determine the type and capacity of equipment used, as well as related issues. When designing, it is not only about the cost of equipment, but more importantly, it is necessary to comprehensively consider the impact of material properties on quality, conveying volume, conveying distance, conveying route, as well as the difficulty and cost of operation and management. For example, for certain materials, the conditions of various equipment are suitable for pneumatic conveying, but when pneumatic conveying cannot be used due to the high moisture content and adhesion of materials, even if the cost of mechanical conveying equipment is high, mechanical conveying method must be selected.

When the economy is relatively reasonable, mechanical conveying is generally advantageous for shorter distances of transportation; On the contrary, for long-distance transportation, although using a pneumatic conveying system is disadvantageous in terms of required power, it is often advantageous in terms of equipment cost. The equipment cost, required power, and operating costs vary greatly depending on the surrounding conditions, so they cannot be compared in a general way. At the same time, it should be noted that the magnitude of changes varies greatly depending on the situation of various platform supports and ancillary equipment. In short, when designing a pneumatic ash removal system, appropriate conveying systems and corresponding equipment should be selected based on specific engineering conditions and comprehensive technical and economic comparisons.
