An Air Insulation System To Insulate The Hot Surfaces Exposed To Human Beings Of A Ducting Arrangement In A Thermal Power Plant

Abstract: The invention relates to an air insulation system to insulate the hot surfaces exposed to human beings of a ducting arrangement in a thermal power plant, the ducting arrangement comprises a rectangular cross sectional member (1) generating a hot-surface during operation, a casing support (6) provided on top of the hot-surface (1), and a cladding sheet (3) supported by and secured on the casing support (6) to transmit the structural including live load of the arrangement, the air insulation system comprising; an air-gap (9) configured between the hot surface (1) and the cladding sheet (3); a highly reflective coating (8) provided over the hot surface (1) to reduce heat transfer through radiation to the cladding sheet (3) from the hot surface (1), wherein the air entrapped in the air-gap (9) acting as a substantially stagnant air with a velocity nearly between 0.1 to 0.2 m/s reducing the convective heat transfer to the cladding sheet (3), and wherein the height of the air-gap (9) is maintained greater than the height of the stiffener. {FIGURE 2}
