Obiettivo To demonstrate that an economic energy saving of about 720 TOE/Y can be achieved in a plaster industry, by substituting the conventional kilns for plaster's humidity evaporation, with a new type of recuperative kiln.The production of this kiln is nowadays of 7 tons. per hour in steady stat. So the annual production, in 290 days per year, can be estimated in 49.200 Tm. per yearThe checked consumption for the cameras kiln can be estimated in 310.815 kcal. per ton., in relation to the necessary 427.172 kcal per ton. with the traditional of two cameras. The checked saving by ton. produced is 116.357 kcal per ton. and with a production of 49.200 ton. per year, the saving is of 596,3 TEP per year.The fundamental saving obtained was in the sensible heat losses of the product, which have dropped from 142.600 kcal per ton., with a saving of 72 % because of these losses and the radiation of the walls losses have dropped from 46.545 kcal per tm. to 25.539 kcal per ton with a saving of the 45 % in this chapter.However, the registered losses because of the smoke and gas which were 53.892 kcal per ton. have reached 82.525 kcal per ton with an increase of 53 %. It happened because the construction of thenew kiln. The gas circuit is more complex, having to drive the gas of the 4 cameras with change in the way of them. So it is necessary a bigger depression in the kiln inner.The technical-economical success with the realization of this project in proved with an energy saving of 596,3 TEP per year.A concentrical, anular chamber, rotating kiln allows counterflow of combustion air and exhaust gases and minimizes the external dissipative kiln surface.
