Definitions
- the invention relates to a gas heat exchanger with a furnace space, a burner chamber, an outer chamber surrounding it and heat exchanger tubes for the combustion gases that make up the furnace space pull through and open into the burner chamber, the Space between the outer chamber and the burner chamber with a fluid can flow through.
- Such a gas heat exchanger is already, for example known from EP-A-519 303.
- the burner chamber in its ceiling is one of the number of heat exchanger tubes corresponding number of exhaust openings on which with a tapering towards the heat exchanger tubes Circumferential edge are provided.
- the one surrounding the burner chamber Outer chamber has openings aligned with the exhaust openings on, each also with one towards the heat exchanger tubes tapered peripheral wall are provided and on each attached to a heat exchanger tube essentially gas-tight is where the space between the inner wall of the Outer chamber and the outer wall of the burner chamber in the direction on the annular gap between the peripheral walls of the exhaust openings and the openings communicate with the ambient air and can be flowed through by air.
- the object of the present invention is to provide a known gas heat exchanger to train such that its efficiency is improved by simple constructive means.
- this task is based on a generic Gas heat exchanger by the characteristics of the characteristic Part of the main claim 1 solved. So it says in addition at least one guide channel for guidance to the heat exchanger tubes from the space between the outer chamber and the burner chamber escaping fluid in contact with the furnace chamber and / or the wall thereof. Here this will be in the space between the outer chamber and the burner chamber flowing fluid over the hot outer wall of the burner chamber heated and then through the guide channel that the Furnace room additionally heated, directed. This will not only the waste heat of the combustion gases arranged in the burner chamber Gas burner used, but also as a secondary heat source heated burner chamber wall, which otherwise the heat in the would radiate environment.
- the guide channel not only for heating, but also for targeted cooling of the Furnace chamber if there is a correspondingly pre-cooled fluid, only briefly in contact with the hot wall of the burner chamber has come through.
- a structurally preferred embodiment can consist in that the at least one additional guide channel the furnace chamber similar to how the heat exchanger tubes pass.
- the guide channel can also be placed around the furnace space and thus additionally heat the furnace space via its outer wall. It is also possible that, on the one hand, a guide channel guides the furnace chamber runs through, while on the other hand a flat guide channel wholly or partially led around the outer surface of the furnace chamber is.
- the one flowing through the space between the outer chamber and the combustion chamber Fluid can be similar via conventional heat convection the chimney effect - set in motion.
- the Fluid by means of a fan or a pump - i.e. in the form forced convection - to be set in motion.
- the fluid can also move through the combustion gases be transferred.
- the fluid is advantageously already set in motion before it flows around the furnace chamber within the guide channel or flows through it.
- FIG. 1 shows a burner chamber 10 with a gas burner 12, that of an outer chamber 14 leaving a gap 16 is surrounded. Extends above the outer chamber 14 there is an oven space 18.
- the oven space 18 is made of heat exchanger tubes 20 pulled through, the gas-tight in the ceiling 24 of the Open the burner chamber 10. Inside the ceiling 24 of the burner chamber 10, which is designed as a heat shield, are openings 26 provided at the points where the heat exchanger tubes 20 flow into.
- Around the outer wall 30 of the furnace chamber 18 around a guide channel 28 is guided, which with the space 16 between the outer wall 32 of the burner chamber and the outer chamber 14 is formed. In the space 16 is by means of a fan 34 blown ambient air.
- the in the space 16 ambient air blows in over the hot outer wall 32 of the burner chamber and is thereby heated.
- the corresponding heated air then flows through the guide channel 28 around the outer wall of the furnace space 30 and thus leads to a additional heating of the furnace chamber 18.
- the guide channel 28 opens into a fume cupboard 22, as does the heat exchanger tubes 20.
- FIG. 2 shows an alternative embodiment of the invention shown that, as far as the differences in the following are not in the are explained individually, otherwise as the embodiment according to Fig. 1 is constructed.
- the guide channel 28, which is also tubular here, opens also here in the intermediate space 16, as shown in FIG. 2 is.
- no opening 26 is provided.
- a gap 34 of the burner chamber 10 is left open. Here you can through the hot wall 32 or 24 heated air into the guide channel 28 flow in.
- 3 and 4 are examples of how corresponding Guide channels 28 can be arranged. These lead to these embodiments similar to the embodiment 2 in the cover 38 of the outer chamber 14 and are connected to the space 16.
- the burner chamber 10 two heat shields 24 side by side arranged in which the corresponding openings 26 except are on which the heat exchanger tubes not shown here 20 connect.
