Case Study: Power Generation – China

Reducing Baghouse Emissions in Coal-Fired Power Plant In China To Meet Demanding Regulatory Requirements

For this Coal-Fired Power Plant, our technical team worked with the Chinese OEM to develop a customized filtration solution, a low-emissions filter media that specifically addressed the client’s need to meet the lower PM benchmark.

Micro-denier fibers were introduced into the fabric structure to optimize the surface filtration media’s efficiencies. This allowed improved particulate capture and increased the rate of dynamic filtration resistance.

Several media were developed and rigorously tested under dust load in the VDI machine in our In-House Laboratory. The resultant high-performing PPS filter media was then successfully trialed on-site at the plant before the full installation of the SOLAFT® Low Emission Filter Bag.

Challenge

China has a strict policy around baghouse particulate emission levels and is under a high level of regulatory scrutiny, with violations attracting significant penalties and/or forced shutdowns.

An existing Coal-Fired Power Plant needed to improve their emission compliance three-fold without a structural baghouse retrofit, and without adversely affecting differential pressure (DP) or filter bag life. They turned to our team to find a cost-effective solution for reducing baghouse emissions to meet increasingly stringent regulatory targets.

Solution

As a result of our filtration solution, the Coal-Fired Power Plant achieved the following key benefits:

  • 97% removal of PM benchmark particles under full-load capacity
    conditions
  • Particulate emissions have been maintained below 3 mg/m³
  • The baghouse has successfully maintained its operating Differential Pressure (DP)
