Power Plant Costa Rica

In this diesel-fired power plant, exhaust air is cleaned by means of two electric filters. Respectively two trough chain conveyors per filter serve for evacuating the ash. For each line, a collecting trough chain conveyor is provided receiving the ash. From there, the ash is transferred to the truck loading station.

To prevent false air from being aspirated via the trough chain conveyors, a sluice has been incorporated between the collecting and the subsequently mounted trough chain conveyor.

The control air is processed by means of two screw compressors.
