FIELD: cellular frameworks subjected to electric heating with nonuniform distribution of heat production. SUBSTANCE: cellular framework is formed from, at least, one sheet which is wound or laid by layers with formation of many channels permeable by gas or liquids. Channels have holes directed to opposite ends of cellular framework, between which the framework is confined by side surface. Formed in framework layers is, at least, one electric conducting circuit possessing some specific resistance with nonuniform distribution along its length through which electric current is passed to heat cellular framework. EFFECT: higher efficiency. 12 cl, 3 dwg
