Fine particle filter for combustion system of solids, such as pellets or chopped wood, comprises purge air supply device, where purge air of purge air supply device is generated by electrically driven piston pump

摘要

The fine particle filter (6) comprises a purge air supply device (14), where the purge air of the purge air supply device is generated by an electrically driven single or two-way or multiple piston pumps (17). An impulse or shock wave is added to the fine particle filter by a quick air relief valve (9A,9B). An independent claim is also included for a combustion system for combustion of solids, such as pellets or chopped wood.
