Abstract: The diathermic fluid heat generator comprises a plurality of pipe nests for fluid circulation, which define the internal walls of a combustion chamber, where the diathermic fluid is heated directly by radiation; and at least a pipe nest in a conveying path for the combustion gas, where the fluid is heated in countercurrent by convection. A fluid distributing header unit comprises an inlet header section, an outlet header section and a main header section having an annular form, positioned at the front side of the combustion chamber. The pipe nest of the gas conveying path is connected in series to the pipe nests of the combustion chamber, by the main header section.
Abstract: A method and a unit for the thermal destruction of industrial fluid wastes in which first and second heating phases are performed by mixing the combustion gases with the fluid wastes into combustion chambers, maintaining the mixture under high turbulence conditions to bring it to a thermodestruction temperature at which the mixed fluid waste is destroyed by heat; the gaseous mixture is maintained in adiabatic conditions at the thermodestroying temperature for a predetermined period of time along a path extending along most of a primary combustion chamber of the destroyer unit. The thermodestroyer unit has a monolithic structure which develops vertically, comprising a primary combustion chamber and an annular stay chamber, which surrounds the primary combustion chamber in which the burning mixture is maintained in a substantially adiabatic condition; the apparatus may be provided with a heat exchanger arranged at the outlet of the stay chamber.
