Definitions

  • the present invention relates to a system for producing thermal energy.
  • the fuels used in such boilers are substantially of three types: methane or natural gas, fuel oil and liquefied petroleum gas, also called LPG. These fuels comprise hydrogen in their molecule and thus water vapor is present in the flue gas.
  • WO 2006/111317 describes an heat exchange apparatus, particularly a condensing boiler, provided with an outer enclosure adapted to delimit a portion of space for containing the fluid to be heated, which is fed cold by means of a return duct located proximate to the base and flows out hot by means of a delivery duct located proximate to the top of the enclosure. Such portion is crossed by flue gas conveyance tubes.
  • the apparatus further has a bell-shaped element, which is located proximate the top of the abovementioned portion and is open at the lower end and closed at the top end.
  • the bell-shaped element is provided with a thermostatic device adapted to allow the fluid contained therein to flow out when a preset temperature is reached.
  • the Applicant has noted that the condensation process is the more effective, the lower the temperature of the return water of the heating installation, which is the fluid used for cooling the condenser of the boiler. In this way, the Higher Heating Value of the fuel is exploited rather than the Lower Heating Value, which is exploited in conventional boilers.
  • the energy saving installation employs radiating panels, fan coils or air treatment units, wherein the heating water temperature is in the first case about 35°C on the delivery side and 30 0 C on the return side, in the other cases 45°C on the delivery side and 40 0 C on the return side.
  • the temperature of the flue gas leaving the condenser is about 35-40°C for installations with panels, and 45-50 0 C in the other two cases considered above.
  • the saturation temperature of the flue gas or dewpoint temperature is about 54°C and the humidity content is about 154 grams/m 3 .
  • the amount of water vapor which is condensed is about 60 grams/m 3 if the temperature of the flue gas leaving the condenser is 40 0 C and about 40 grams/m 3 if the flue gas temperature is 45-50 0 C.
  • the thermal recovery of a condensing boiler is limited by the temperature of the return water in the installation and in many cases, such as for example in installations with radiators, condensation is not possible or takes place only at the beginning and at the end of the season, when the heating needs are reduced and thus the heating water temperatures are relatively low.
  • the Applicant has thus noted that the use of condensing boilers often does not allow recovery of the latent heat of the water vapor contained in the flue gas, but in many cases just of the sensible heat, with short periods of time in which the latent heat recovery is possible.
  • the Applicant has found that by preheating the temperature of the thermal fluid entering the boiler and increasing the recovery of the heat of condensation of water vapor contained in the flue gas for achieving an average efficiency higher than 100% referred to the HHV (Higher Heating
