Solid fuels are very dangerous, so they must be handled with extra precaution because they are possible to create an explosive environment inside the de-dusting filter.
These type of filters are designed with the ATEX standards, requiring an enforced construction with anti-explosive membranes in order to relief an occurring explosion.
At the designing phase we must consider the high temperatures inside the filter, in order to choose the proper type of filter-cloth and also the installation of automatic bypass mechanisms required for the filter protection.
