Definitions

  • the object of the invention refers, in general, to the industrial sector of solid fuel boilers, and, more particularly, to a gas heat exchanger in a solid fuel boiler.
  • boilers which use solid fuels and which, to use the heat of gases, include a heat exchanger constituted by a plurality of straight and parallel tubular conduits in a primary circuit of water in the environment of the combustion chamber are known. These boilers are known generically as "smoke tubes”.
  • smoke tube boilers are described in patent documents ES2237230 , ES2156689 , ES1059434 , and ES0312179 .
  • the object of the invention is a heat exchanger having a new structure which, in it or in a very similar structural volume of the boiler itself, has a much larger exchange surface, so that one uses much more heat from the gases and therefore the boiler is more efficient.
  • the boiler is characterized by the fact that, consisting of a combustion chamber in which the gases are generated at high temperature, and that, consisting of a primary circuit of water around this combustion chamber, one has a plurality of tubular conduits of helical configuration communicating respectively by their ends with the combustion chamber in which the high temperature gases are produced and with the gas recovery chamber, to which they arrive cooled thanks to the large exchange surface with the primary circuit of water in which they are immersed.
  • tubular conduits of helical configuration are grouped in one or more series, which confluence at the entrance to the combustion chamber and at the outlet, in the gas recovery chamber.
  • the object of the invention is a gas heat exchanger for solid fuel boilers of the type known as "smoke tube”.
  • these boilers are constituted by a combustion chamber (1) with one or more burners (2) of solid fuels that produce high temperature gases in the combustion chamber (1).
  • a combustion chamber (1) with one or more burners (2) of solid fuels that produce high temperature gases in the combustion chamber (1).
  • burners (2) of solid fuels that produce high temperature gases in the combustion chamber (1).
  • straight tubular ducts are arranged, in which the gases advance towards a recovery chamber while they are cooled by exchanging their heat with a primary circuit of water where these tubular ducts rights are immersed.
  • one or more curved tubular ducts (4) are arranged, immersed in the primary water circuit (3) and embracing the entire perimeter of the combustion chamber (1).
  • these tubular ducts (4) in spiral or helical form leave the combustion chamber (1) from which they receive the hot gases; they surround the perimeter of the combustion chamber (1) as long as they are immersed in the surrounding primary water circuit (3), to exchange heat with it and to cool, and they reach the gas recovery chamber (5), where they arrive, cold or almost cold, to be evacuated through the chimney (6).
  • sub-circuits (4a), (4b), (4c) are arranged, independent and interposed to form a general assembly around the perimeter of the combustion chamber (1).
  • These sub-circuits of spiral or helical configuration, converge in a common inlet and outlet so that a maximum heat exchange area is obtained and, therefore, an optimization of the efficiency of the boiler.
