Abrasive Material Handling

With the fast electrification of rural India and more industries being formed, the demand in unhindered power is at a significant increase in India. To meet the needs and make it possible, Coal-fired power plants are starting to gain more recognition in their ability to actually achieve stable power supply systems.

In Thermal Power Plant’s coal is generally used as fuel and hence the ash is produced as the byproduct of Combustion. Ash generated in power plant is about 30-40% of total coal consumption and hence the system is required to handle Ash for its proper utilization or disposal.

Ash Handling systems are designed to collect, transport and dispose of the discharged ash through pneumatic and mechanical methods. These systems are also used in industries like construction and cement.

In coal fired power plants 80% of the ash that is discharged is fly ash, which is collected using an Electrostatic Precipitator. It is then disposed in dry form by methods of dense phase pneumatic conveying (negative or positive pressure).

This entire process occurs through pipelines which require various forms of Pneumatic Valves which acts as gates in different parts of the ash handling system based on application requirements.
