One challenge is to collect all the resulting ash, which difficult as it is, represents just the tip of the iceberg. The real challenge is to transport all this ash outside the factory, in a manner that is both environmentally friendly, safe for the workers and cost effective. When it comes to fly ash handling, you need powerful conveyors and not the regular ones which are used for transporting regular products on short distance. Ash needs special attention and since the distances will frequently span over 1000ft, it is easy to understand why top technology has to be used.
A vacuum system is superior to the positive-pressure system, because it has lower construction cost for the baghouse, with the installation and maintenance being minimal. In this industry, costs mount quickly, and if you want to cut down on expenses, without impairing fly ash handling, you will appreciate the vacuum system. Another major benefit is that this can stop and restart automatically, which translates into higher efficiency and a cleaner environment.
