It is essential for companies to safeguard the environment for survival and pursue sustainable development. To adhere to global environmental protection regulations, there is a need for more demanding specifications for an enterprise’s flue gas dust removal system, particularly in terms of the filter material and heat exchanger system. NHU’s PPS material can be of tremendous help for this purpose and make a great contribution in improving air quality.

Thermal power generation industry: PPS fiber is a commonly used fabric in the industrial boiler filter bag. This is due to its ability to endure the waste heat flue gas emitted from industrial furnaces, which typically contains a considerable amount of corrosive chemicals, for instance, nitrogen oxides, sulfur oxides and halogen acids. Compared to other chemical fiber materials, PPS fiber stands out with its robustness and longevity, with an estimated service life of up to three years.

Cement industry: The cement industry is increasingly relying on bag filter technology being employed in kilns of new dry process cement production lines. PPS fiber filter material has proved to be a useful asset.

Flue gas heat exchanger are a crucial part of flue gas waste heat recovery and white smoke removal systems. These systems generate a highly corrosive condensate as a result of flue gas condensation. Oftentimes, industries utilize either expensive fluoroplastic heat exchangers or metal heat exchange tubes with anti-corrosive coatings to guard against corrosion; however these methods can be costly and have a limited lifespan.

Heat exchange tubes with both high thermal conductivity and corrosion resistance are commonly used for chemical heat exchanger purposes. Metals such as alloy metal and specialized metal possess both qualities and cost more than simple metal heat exchangers, but are still widely used due to their longevity and high resistance to temperature. Graphite block heat exchangers are cost-effective but with a shorter service life, and lower service pressure.

Thermal conductive PPS tube boasts several advantageous qualities. It is renowned for its outstanding thermal conductivity, effective corrosion resistance, susceptibility to high temperatures, high burst pressure. Its level, non-scaling surface makes it a tough and reliable option, ideal for the rigorous conditions presented by the chemical and thermal power flue gas sectors.
