In a coal-fired power plant, flue gas is produced when coal is burned to generate electricity. The flue gas typically consists of a mixture of gases, including carbon dioxide, water vapor, and nitrogen, as well as small amounts of other pollutants such as sulfur dioxide, particulate matter, and heavy metals.
Particulate matter is a type of air pollution that consists of tiny particles that are suspended in the air. It can be inhaled into the lungs and cause respiratory problems.
Fabric filters, also known as baghouses, use a network of fabric bags to capture pollutants from flue gases. The flue gas is passed through the fabric bags, and the pollutants are trapped in the fabric. Fabric filters are effective at removing particulate matter.
The flue gases produced by a coal-fired power plant can have temperatures that range from 140 to 400 degrees Celsius. So the fabric filters needs to withstand the pressure and temperatures of this Hot Gas Filtration process 24x7.
Here Technical Textile like Glass fabric comes to our rescue.
Glass fiber fabric has several properties that make it well-suited for use in flue gas filtration. It is strong, durable, and resistant to abrasion, making it less likely to tear or wear out over time. It also has a high resistance to heat and chemicals, making it suitable for use in high-temperature and corrosive environments.
In addition to its practical properties, glass fiber fabric is also an environmentally friendly choice for flue gas filtration. It can be recycled or disposed of in an environmentally responsible manner, and it does not produce harmful emissions when it is burned.
Ok, ok, will talk about PTFE also. For enhancing the performance of glass filter fabric, we use PTFE (Polytetrafluoroethylene or Teflon)
Glass PTFE fabric is made by coating a layer of PTFE (polytetrafluoroethylene) onto a layer of glass fiber fabric. This creates a material that has the strength and durability of glass fiber fabric, as well as the chemical resistance and low friction properties of PTFE. This makes glass PTFE fabric well-suited for use in flue gas filtration, as it can withstand high temperatures and corrosive gases without breaking down or wearing out.
Glass PTFE fabric is a high-temperature material that can withstand continuous temperatures up to 260 degrees Celsius (500 degrees Fahrenheit). It is also worth noting that although glass PTFE fabric can withstand continuous temperatures up to 260 degrees Celsius, it may experience some degradation or loss of strength at these high temperatures over time. This can affect the performance of the filter and may require the filter to be replaced more frequently.
Not making the post too long, will talk about the configuration
and installation of filtration system using Glass PTFE fabric in a separate post.
Till then, Stay Safe, Wear Mask and Save Soil
