FIELD: power engineering.SUBSTANCE: by means of installation of a heating cable along a shell, stiffening ribs and parts of grid fixation with further application of a heat insulating coating on them, thermal energy is accumulated in massive parts and sent to less massive louvers, which have contact with heated parts by metal.EFFECT: method and device make it possible to eliminate icing of grids with simultaneous preservation of gaps between louvers required to let air through in the specified volume without considerable increase of dimensions of ventilation grids.4 cl, 1 dwg |
