The increasing global demand for energy shows no sign of abating and the cleaner production of electricity is a target for many economies. While coal continues to be the dominant fuel being burned in the plants of utility power providers, the additional use of biomass is on the increase.

Equally, the reduction of waste being sent to landfill and the need to recover the energy from material that cannot otherwise be recycled is leading to a significant number of Energy-from-Waste (EfW) sites with a variety of materials being combusted to generate heat to produce steam to drive turbines and generate electricity. Many stand-alone plants now process all manner of waste types; municipal, clinical, industrial, hazardous, sewage sludge, paper sludge – the list is long and increasingly varied.

The flue gases from these combustion processes require cleaning to remove the numerous gaseous and solid pollutants, the emissions of which are tightly controlled and closely monitored.

The very nature of the process ensures the flue gases are often high temperature and chemically aggressive which, coupled with the requirements for low particulate emission levels and the need to maintain good draft through the system, places great emphasis on the quality of the filter media to be employed in any fabric filter gas cleaning system.

Lydall Industrial Filtration Asia have been actively engaged over many years in the development and supply of our power generation range of filter media which has been designed to meet and exceed the requirements of the growing energy market.
