Prevent Scaling in Coal Power Plants with Liquid Filtration

Updated: Oct 20, 2020

Liquid filtration is a critical element in power generation systems. The global demand for energy is accelerating and proper filtration is key to achieving maximum results, efficient costs, and environmental performance while being regulation-compliant.

Coal-fired power plants have been an integral part of the world’s power grid for the past century. In Malaysia, there are 6 coal power plants. In a coal-fired power plant, coal is pulverized to a powder and strategically fed into a boiler along with preheated air where it is burned to generate heat.  The boiler contains heat exchange tubes with water that is converted to steam in the plant’s boiler. The high pressure steam then acts as a catalyst to drive the turbines that ultimate drive a generator to create electricity.

The water used for the boiler can lead to problems if not properly filtered and maintained.  Plants generally use make-up water in their systems, which is typically derived from a natural body of water such as a river or lake. This water contains particulates and semi-solid biological materials which will transfer onto equipment surfaces if not filtered.  If not filtered correctly, these impurities will be precipitated out of the water directly on heat transfer surfaces.  This is known as scaling.  Proper filtering of the make-up water is critical to eliminate scaling due to the high level of particulate.  Don't allow your equipment to be contaminated and damaged by dirt residue and particulates. We distribute liquid filters from Graver Technologies that has been a recognized leader for over 30 years in the supply of filtration products for the power generating industries.
