Definitions

  • the subject of the present invention is a hot water production installation comprising an outer casing, an upper closure plate, a lower closure plate, a burner with an injection device and a combustion chamber comprising smoke tubes arranged in the interior of the chamber. envelope, and at least one tank / exchanger or exchanger disposed within the casing, the inner space of the casing having an upper portion and a lower portion. It relates more particularly to a condensing plant that can be used for central heating and / or production of hot water for domestic, tertiary, industrial or other.
  • Condensing boilers have been developed to recover maximum energy from the combustion gases. Indeed, when the temperature of the combustion gases falls below about 50 ° C, condensation droplets form on the heat exchanger elements and fall by gravity to the lower zone of the boiler. This condensing liquid is very corrosive and it is therefore avoided to place the burner in the bottom of the boiler because of rapid degradation thereof.
  • annular tank in tank a device made using the technique of the submerged tank (called “annular tank in tank”), commonly used by the applicant, gives very good results from the point of view of exchange and thermal efficiency, such as as already explained above.
  • This technique involves immersing an annular cylindrical reservoir, which contains domestic hot water, in a second external reservoir which forms the primary circuit.
  • the flue tubes exchange their heat in the primary circuit, which, in turn, exchanges its heat with domestic hot water through the walls of the tank / exchanger at a lower temperature.
  • the primary circuit is, depending on the case, either used for a heating circuit, or remains closed for a strict production of hot water.
  • a heating system for producing hot water for heating and domestic hot water.
  • the installation comprises an outer casing, an upper closure plate, a lower closure plate, a burner with a combustion chamber, and tubes for the passage of flue gases from the combustion chamber, said tubes serving as a heat exchanger.
  • the casing further comprises a coil in which the domestic water flows to heat it, and connections for connecting it to a central heating circuit.
  • the combustion chamber divides the envelope into a lower part located below the combustion chamber, the lower part into which the tubes for the passage of fumes extend, and an upper part situated above the combustion chamber. forming a reservoir in which no tube extends for the passage of fumes.
  • the upper part or small volume tank is not heated by the passage of fumes.
  • the object of the present invention is to combine the advantages related to the so-called "tank in tank” technique with the technique of condensing boilers in order to obtain a thermal installation capable of supplying central heating water as well as the sanitary water in any condition and with a yield close to the theoretical maximum yield.
  • the installation object of the present invention is distinguished in that it has the characteristics as specified in the appended claims.
  • the invention therefore relates to a hot water production installation comprising an outer casing (1), an upper closure plate (2), a lower closure plate (3), a burner (4) with a device injection (5) and combustion chamber (6) comprising rocket tubes (7) arranged in the casing (1) and at least one tank / exchanger or exchanger disposed inside the casing (1).
  • the interior space of the envelope having a partition (11) creating in the envelope (1) an upper portion (12) and a lower portion (13), characterized in that the upper and lower portions (12,13) are a lower chamber (13) and a superimposed upper chamber (12), the upper chamber (12) of which is continuously maintained at a high temperature, in that said upper and lower chambers (12,13) and the partition wall (11) are traversed by the flue tubes, in that the partition wall (11) comprises a communication device (23) between the upper and lower chambers (12, 13), and in that the burner (4) is placed on the upper closure plate (2) so that the flow of fumes is vertically from top to bottom by the flue tubes (7) passing through both chambers (12, 13) constituting the two primary circuits of the installation, the upper chamber (12) working at high temperature, while the lower chamber (13) is operated at low temperature in the fumes condensation zone.
  • the figure shows a block diagram of a boiler device according to the invention.
  • the boiler comprises an outer shell 1, generally cylindrical, comprising an upper closure plate 2 and a lower closure plate 3.
  • the lower part of this combustion chamber 6 is connected with a series of flue tubes 7 which extend downwards to the lower closure plate 3.
  • These tubes 7 are configured as heat exchangers, so that to absorb and distribute as much heat as possible from the flue gases.
  • the chamber 8 is provided with an outlet pipe 9 fumes and a device 10 for recovering and discharging condensates.
  • the boiler illustrated in the drawing, is constructed in two parts, separated in height by a partition wall 11 so as to create an upper chamber 12 and a lower chamber 13; these rooms having different operating temperatures.
  • the upper chamber 12 operates at high temperature and has a large volume of water
  • the lower chamber 13 is operated at low temperature in the condensation zone.
  • the return water from the heating system generally enters a temperature of about 30 ° C through the inlet 16 of the lower chamber 13 and is heated a few degrees before exiting either through the outlet 17 to the valve 19, or by the device 23 of the partition 11 in the upper chamber 12.
  • the water is heated between 60 and 90 ° C before exiting via the valve 19, where it is mixed with the water.
  • about 32 ° C of the pipe 18 for the heating start which requires about 50 ° C. It is therefore understood that the water in the upper chamber 12 will be constantly maintained at temperatures between 60 ° and 80 ° C while that the temperature of the lower chamber 13 will be maintained within a range of a few degrees above the heating return temperature.
  • each of these chambers 12, 13 there is in each of these chambers 12, 13 a tank / exchanger or an internal exchanger, completely immersed in their respective chambers.
  • a tank / exchanger 14 annular and coaxial with respect to all of the flue tubes 7 and the outer cylindrical casing 1.
  • This reservoir / exchanger 15 is also annular and coaxial with respect to all the flue tubes 7 and to the outer cylindrical shell 1.
  • the temperature of the upper chamber 12 is maintained at a uniform temperature, possibly through a primary circulation loop.
  • the two chambers 12, 13 are irrigated by different flow rates of water through the action of the three-way valve 19; the flow rate is maximum in the lower part to promote condensation and limit the increase in temperature.
  • the flow rate in the upper chamber 12 is defined by the position of the three-way valve 19.
  • the flue gas circuit comprises only one passage through the tubes 7, which simplifies the construction and reduces the bulk.
  • the upper part with the chamber 12 is maintained at a homogeneous temperature greater than 60 ° C. by a regulating device acting on the three-way valve 19.
  • the volume of the lower chamber 13 (low temperature) is limited, which reduces the inertia when switching from a high temperature operating mode to a low temperature operating mode.
  • the hot water production system manages to solve the problems posed and to propose a multi-purpose boiler, combining the following advantages: condensation in heating mode and domestic hot water mode, storage d Integrated high-temperature sanitary water (> 60 ° C), high production of domestic hot water.
  • the condensation mode is reached in heating mode as well as in sanitary mode but also in mixed operation (sanitary + heating).
  • Heating operation at very low temperature becomes possible, while maintaining the hot water storage at very high temperature.
  • the boiler according to the invention therefore comprises two primary circuits operated at different temperatures.
  • the part superior operates at high temperature and includes a tank / exchanger for the production of domestic hot water.
  • the burner is placed at the top of the boiler and the flow of fumes is vertically from top to bottom in an exchanger that passes through the two primary circuits.
  • the flow rates of water in each of the primary circuits are regulated according to the desired flow temperature.
