Originální abstrakt
A quite new unique equipment for the thermal treatment of gas wastes (incineration of volatile organic compounds contained in polluted air) has been developed. This compact equipment is characterized by a cylindrical combustion chamber which is placed inside a heat exchanger polluted air preheater. This cylindrical preheater consists of several concentric stainless sheets. Both flue gas from the combustion chamber and polluted air (which is heated by flue gas) flow in the spaces between each couple of cylindrical sheets. Narrow distance strips which are placed between the sheets form helical rectangular ducts. Thus we can reach counter-current flow of process fluids. Mathematical model for the calculation and/or simulation of the equipment consists of submodels of heat exchanger, combustion chamber and annular space in between them. Based on results of measurements on an industrial scale experimental facility new correlations for the thermal and hydraulic calculations of the heat exchanger were developed. Some industrial applications are briefly mentioned.
Český abstrakt
V nedávné době bylo vyvinuto nové zařízení pro tepelné zpracování plynných odpadů ze znečištěného vzduchu. Základní myšlenka celého zařízení je založena na vložení válcové spalovací komory do výměníku tepla, předehřívače znečištěného vzduchu. V jednotce se snoubí výhody kompaktnosti a možnosti pracovat jak při podtlaku tak při přetlaku. Na základě měření na experimentální jednotce v provozním měřítku byly odvozeny nové korelace pro tepelné a hydraulické výpočty výměníků tepla.
