Seshasayee Paper and Boards Ltd. – Insulate Dryer End Covers
Reduction of Paper Mfg. Equipment Surface Temperature by 15.7% – 18.7%
Looking to increase energy efficiency in paper manufacturing facility and insulate to improve lifespan of sensor units and insulate dryer end covers
Seshasayee Paper & Boards Ltd. presented a paper at Papertech 2011, held in Hyderabad India. The paper was presented by Dr. T.G. Sundara Raman, Head of Energy and Climate Change Development, Seshasayee Paper & Boards, Ltd, and was presented in the Energy & Environment category. The paper titled, “Energy Conservation Using Nanotechnology Based Insulation Coating in Paper Machine Dryer At Seshasayee Paper” describes the benefits experienced in the pulp and paper industry by using patented Synavax™ thermal insulation coatings for insulation and protection of paper manufacturing equipment.
The facility’s equipment was insulated with Heat Shield™ Translucent PT at a 300 micron (12 mil) dry film thickness (six coat coverage). Dryer end covers were coated and showed an average temperature reduction after 30 days (prior to the full 45-60 day cure time being completed) over one dryer of 39.6 F, a 15.7% reduction in temperature, and on another dryer of 48.6 F, an 18.7% reduction in temperature.
Another piece of equipment insulated to increase sensor and unit longevity was a scanner sensor unit, which showed an average temperature difference of 28.2F, prior to cure time being completed, while also showing more effective sensor functioning due to the lower temperature. Comfort for approaching the operating unit and increased longevity of the scanner unit were benefits also noted in the paper due to the Synavax™ insulation technology.
Applications areas in the paper mill were noted as: Paper machine dryer unit, hot and warm condensate, boiler feed water and process fluid lines, LP steam pipelines and accessories, heat carrying valves and fittings, satellite cooler annulus exterior of lime kiln, heated HFO lines and storage tanks, chiller lines in CI02 unit, CPU-PHE & EOP head covers.
