Definitions
- Flue gases have a temperature of 200 ° C or more when they leave their boiler. These flue gases are mostly cleaned using filter systems and escape at a constant temperature, i.e. at 200 to 300 ° C depending on the system, into the air via a chimney.
- the object of the present invention is to avoid this extreme waste of energy by creating a device which uses the waste heat from the flue gases and at the same time effects cleaning.
- the object is achieved in that the exhaust pipe of a flue gas-generating system is connected to a boiler and that in thermally conductive contact with the boiler or the flue gas one or more separate lines with media to be heated are arranged around or in the boiler, wherein the flue gases are cooled to condensation by the heat exchange and there is a drain for the condensed flue gas at the bottom of the boiler.
- FIG. 1 schematically representing the first embodiment
- FIG. 2 the second embodiment
- FIG. 3 the third embodiment.
- a device 20 for neutralizing the acidic waste water is arranged downstream of the drain.
- the fan 19 downstream of the outlet 10 is equipped with a trailing mechanism in order to use the residual heat of the boiler 3.
- An experiment shows that the system uses about 80% of the heat from the flue gas.
- the flue gases with a temperature of 250 ° C are cooled to about 40 ° C.
- With a burner output of 5.38 l of heating oil per hour it is possible to generate approximately 170 m 3 of warm air at more than 40 ° C. Even after the system has been switched off, the temperature of the blown air is still 20 ° C higher than the temperature of the intake air for almost 30 minutes.
- FIG. 2 A further possibility for developing the invention is shown in FIG. 2.
- a heat exchanger 11 to which fresh air 9 is supplied.
- This fresh air is then passed through the heat exchanger in a known manner and emerges from the outlet 10 and is also fed to a consumer here.
- the fresh air cools the flue gases until they condense.
- the condensate can again be discharged through the drain 7 and fed to a neutralizer 20.
- FIG. 3 shows a further embodiment of the invention which is particularly suitable for large, flue gas-producing systems with higher flue gas temperatures.
- a heat exchanger 11, to which fresh air 9 is supplied, is again arranged in the lower part of the boiler 3.
- the heated air can be used in the manner already mentioned.
- a smooth register 12 is installed through which water 13 is passed for a heating system.
- the flue gas is again extracted by so much heat that it cools down to below its dew point.
- the condensate with a large part of the pollutants is drained off and disposed of via the drain 7 and the neutralizer 20.
