A wind scavenger including a frame, a litter collection unit, a lower gear-wheel assembly, an upper gear-wheel assembly, a net element, and a fan system is provided. The litter collection unit is attached to a base member of the frame. The litter collection unit includes a receptacle for collecting litter. The net element includes flexibly jointed plates for catching the litter blown by wind. The fan system is connected to the upper gear-wheel assembly via a power transmission system. The fan system, in communication with the wind, rotates the upper gear-wheel assembly and in turn rotates the net element around the upper gear-wheel assembly and the lower gear-wheel assembly and vice versa. The rotation of the net element from the upper gear-wheel assembly to the lower gear-wheel assembly conveys the litter caught by the flexibly jointed plates of the net element into the receptacle of the litter collection unit.

A particle discharge device for a filter assembly has a housing with a valve seat, wherein the valve seat surrounds at least partially a symmetry axis of the housing. One or more particle discharge flaps embodied as one piece together with the housing are provided. The one or more particle discharge flaps are moveable from a closed state into an open state for discharging particles from the filter assembly. The one or more particle discharge flaps are resting against the valve seat in the closed state. A filter assembly is provided with a filter housing having a particle discharge socket in which the particle discharge device is arranged.

A gasifier system configured to generate synthesis gas via thermal decomposition of materials at elevated temperatures in an oxygen deprived atmosphere via pyrolysis is disclosed. The gasifier may include numerous subsystems configured to increase the operational efficiency of the gasifier. For example, and not by means of limitation, the gasifier may include a syngas recirculation system, a screenless ash removal system, a tar reduction system, a negative slope gasifier system and a syngas catalyzer system. The syngas recirculation system may increase efficiency of the gasifier system.
