ABSTRACT:
The present invention provides a unique structure for concentrating mineral acids, and particularly sulphuric acid wherein a plurality of long quartz tubes extend vertically through a furnace and have vertically lower ends in communication with a receiving vessel. The quartz tubes are surrounded by tube units and flow passageways are created on either side of the tube units for directing hot combustion gases along the quartz tubes, providing convective and radiative heat transfer to the tubes as required to heat the acid flowing therethrough. An assembly is positioned for generating turbulance within the gas flow passageway to achieve a vigorous turbulance of the hot combustion gases.
