In this blog, we examine the benefits of utilizing a Precoat Filter Aid in the start-up of the baghouse of a coal-fired boiler, particularly when the filter bags use ePTFE membrane media.
ePTFE membrane laminate offers enhanced baghouse operating performance including enhanced emission control, better bag cleaning, higher collection efficiency, and reduced energy costs.
Proper use of a good Precoat Filter Aid can mitigate the sensitivity of ePTFE membrane to Volatile Organic Compounds (VOCs) and serve as a protective measure against upset conditions prevalent in a coal-fired boiler start-up. In the figure on the right, precoat is being injected into the baghouse.
