Heating device

Abstract

Generally described, a heating device, or heating tube, includes a combustive fluid inlet, respectively a combustible fluid inlet, is connected to a combustion head via a first pipe, respectively a second pipe, the second pipe being housed at least partially in the first pipe. In this heating device, the combustion head is distant of at least 50 cm from the combustible fluid inlet, which enables to create a “cold zone” between the two. The first and the second pipes enable to bring the combustible fluid and the combustive fluid separately to the combustion head, even if the latter is remote by at least 50 cm from the combustible fluid and combustive fluid inlets.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

 the combustive fluid inlet and the combustion head via the first fluid connection; and 
 the first part of the heat-emitting tube and the second part of the heat-emitting tube, 
   wherein the combustion head and the combustible fluid inlet are separated by a distance of at least 50 cm, and wherein that the combustion head and the combustive fluid inlet are separated by a distance of at least 50 cm.   
     
     
         2 . The heating device of  claim 1 , wherein the combustion head and the combustible fluid inlet are separated by a distance of at least 2 m. 
     
     
         3 . The heating device of  claim 1 , wherein the combustion head and the combustible fluid inlet are separated by a distance of at least 10 m. 
     
     
         4 . The heating device of  claim 1 , wherein the combustion head and the combustive fluid inlet are separated by a distance of at least 2 m. 
     
     
         5 . The heating device of  claim 1 , wherein the combustion head and the combustive fluid inlet are separated by a distance of at least 10 m. 
     
     
         6 . The heating device of  claim 1 , further comprising a casing, wherein the first fluid connection comprises, between the combustive fluid inlet and the first pipe, a first connection part included in the casing, wherein the second fluid connection comprises, between the combustible fluid inlet and the second pipe, a second connection part included in the casing, and wherein the combustion head is situated outside of the casing. 
     
     
         7 . The heating device of  claim 1 , wherein the combustion head is mechanically coupled to the first part of the heat-emitting tube by coupling elements fixed to the combustion head and slidably arranged along one or more of an inner surface of the second pipe and an inner surface of the heat-emitting tube. 
     
     
         8 . The heating device of  claim 1 , wherein the heat-emitting tube comprises a section configured for disassembly. 
     
     
         9 . The heating device of  claim 1 , wherein the second pipe is configured to support a temperature of at least 300° C. 
     
     
         10 . The heating device of  claim 1 , wherein the second pipe comprises a metal. 
     
     
         11 . The heating device of  claim 1 , wherein the first pipe is rigid. 
     
     
         12 . The heating device of  claim 1 , wherein the second pipe is more flexible than the first pipe. 
     
     
         13 . The heating device of  claim 1 , wherein the first pipe has an angle, and wherein the second pipe is at least partially flexible and bent. 
     
     
         14 . The heating device of  claim 1 , wherein the heat-emitting tube and the first pipe form part of a same piece. 
     
     
         15 . Heating equipment comprising the heating device according to  claim 1 , the heating device configured for heating at least one of earth for decontamination, a sauna, a furnace, a tunnel furnace, and a chemical bath. 
     
     
         16 . A heating method, comprising:
 providing a heating device according to  claim 1 ;   arranging the heating device such that the heat-emitting tube is at least partially in a zone to be heated;   connecting fluidically the combustive fluid inlet to a combustive fluid supply;   connecting fluidically the combustible fluid inlet to a combustible fluid supply;   starting the means for moving fluid; and   igniting the flame at the combustion head.
