Silo systemsFly ash siloEWB can supply complete silo technologies for ash collection including venting, aeration, level measuring equipment and different kind of discharging facilities. We can provide complete design from small steel silos up to big storage silos with capacity of 5000 m3 made of concrete. We have different type design for silo aeration to ensure the proper flow out of the silos. The type and capacity of the aeration system can be different depending on the size of the silo and the shape of the silo bottom such as, traditional conical bottom, flat bottom, inside cone bottom etc. The discharging arrangement can be also different depending on the shape of the silo bottom portion furthermore how many outlets are required. Of course the fly ash storage silos have to be equipped with level switches, level measuring equipment, safety devices (overpressure/underpressure valves) etc. Silo discharge facilitiesFor smaller discharging capacities rotary feeder is widely used. But for the fly ash silos we prefer to offer our fluid discharging system. This fluid discharging system is a very simple design consists of pneumatically operated cut off gate and manual or motorized flow control gate. The main equipment for silo discharging:
In the inlet chute of the conditioning unloader there is a weight balanced feeder arranged to prevent the vapor going counter direction of flow. In somecasesif from the aeration system too much air is forced to the conditioning unloader the unloader has to be equipped with additional suction. In this case an additional suction fan and a wet scruber has to be provided.
Large ash storage silo stationFor big power plants large ash storage capacities are required.
