Embodiment Construction

[0014] The device shown in FIG. 1 is used to purify a medium, in this case gas discharged or exchanged from a coal mine. Such exhaust gases often contain flammable substances, flammable methane gas. When the inventive device indicated generally at 7 is not in use, the waste air in the mine 1 is sent to the flue 4 by the fan 2 and the valve 3 or to the flue 6 by the fan 5 .

[0015] According to the embodiment shown, the device 7 proposed by the invention comprises four combustion exchangers, which are generally designated 8, 8 I ,8 II ,8 III ,8 IV Indicates that, of course, depending on the field of application, it may also include more or less combustion exchangers. Each combustion exchanger 8 is connected with a plurality of inlet pipes 11 and a plurality of outlet pipes 12 through a process fan 9 shared by all combustion exchangers and a valve 10 provided for each combustion exchanger. According to the embodiment shown, there are 9 inlet conduits and 9 outlet conduits,...

Abstract

The invention relates to a method and device for recovery of energy from a medium containing combustible substances even at low concentrations. The method is characterized by raising the temperature of the medium in a regenerative combustor i. e. a reversal flow direction combustion device wherein the combustion takes place in a warm zone, to the combustion temperature at which essentially all chemical energy of the combustible substances is transformed into thermal energy. The heated medium is then utilized for the production of a wanted form of energy.

Description

technical field [0001] The present invention relates generally to a method and apparatus for recovering energy from a medium containing flammable substances, even in low concentrations, and in particular to energy recovery associated with the purification of said medium by burning flammable substances. Background technique [0002] It is known to purify exhaust gases from, for example, paint and printing shops, containing flammable substances such as solvents, by heating the exhaust gases to the combustion temperature of the flammable substances. However, this treatment is expensive, since the entire gas flow of the exiting medium needs to be heated. It is thus possible to reduce the costs of heating the exhaust gases thanks to a "fired exchanger", an example of which is described, for example, in Swedish patent specification 8903556-2 relating to absorption technology. In said patent specification, a combustion exchanger is defined as a device comprising a heat accumulator...
