Flat gas radiator. - Platt gas battery.

The invention relates to a flat gas radiator comprising a flat flue gas space delimited by vertical walls, with a flange head at the bottom and associated with a flue gas exhaust pipe and a combustion air intake pipe surrounding the flue gas a riser arranged inside the combustion chamber from the burner head upwards for most of the height of the combustion chamber.

Such a gas radiator is disclosed in the applicant's Finnish patent application 812897. It has proven to be very useful in a wide variety of applications. One essential area of application is use in vehicles. In this case, however, the flue gas outlet from the wall of the vehicle is annoying and in many cases is not permitted by the authorities.

The invention has realized that the flow enhancement provided by the riser is sufficient to maintain the flow in the coaxial pipe even if, according to the invention, the coaxial pipe is directed downwards for passage through the floor. It is new and surprising that the smoke extraction duct (chimney) faces downwards.

In the following, an embodiment of the invention will be described in more detail with reference to the accompanying drawing, in which Figure 1 shows a gas radiator according to the invention seen from behind, with the rear vertical wall removed.

Figure 2 shows the same radiator in a vertical section seen from the side.

The vertical walls 13 have a limited flat combustion gas space 15, at the bottom of which is a burner head comprising an ignition burner 10 and an actual burner 9. Gas is led from the gas inlet pipe 1 directly to the ignition burner 10 and to the burner 9 via a thermostat 3.

A riser 11 is arranged above the burner head 9, 10, which extends over most of the height of the combustion chamber 15 and opens into the upper part of the combustion chamber 15. The walls of the riser 11 are detached from the walls 13 of the radiator. Thus, the surface temperature of the radiator is kept low.

Arranged below the burner head 9, 10 is a riser 11 which extends over most of the height of the combustion chamber 15 and opens into the upper part of the combustion chamber 15. The walls of the riser 11 are detached from the walls 13 of the radiator. Thus, the surface temperature of the radiator is kept low.

Below the burner head 9, 10, a fastening piece 14 is attached to the bottom of the heating coil, to which a flue gas outlet pipe 6 and a combustion air intake pipe 5 formed in the form of a coaxial pipe are connected. When the exhaust pipe 6 is located at the lowest point of the radiator, liquid or natural gas heavier than air cannot fill the riser 11 and the combustion space 15. In this case, the re-ignition sensitivity of the burner 9, 10 is maintained. The same goes for flue gases.

By means of the chimney effect of the riser 11, the burner 9, 10 burns so strongly that the relatively small diameter coaxial pipe 5, 6 can be directed downwards for passage through the floor. This decisively improves the suitability of the gas radiator for vehicle use.

In addition, the gas radiator includes a spark plug 7, a flame arrestor and a glass-covered monitoring port 12.

Claims (1)

A flat gas radiator comprising a flat flue gas space (15) delimited by vertical walls (13), with a burner head (9, 10) at the bottom and associated with a flue gas exhaust pipe (6) and a combustion air intake pipe (5) surrounding the flue gas exhaust pipe (5). 6) forming a coaxial tube for the passage of the structure delimiting the space to be heated, wherein in order to ensure exhaust and intake flows in the smallest possible coaxial tube a riser (11) extending from the burner head (9, 10) upwards for most of the combustion head that the coaxial tube (5, 6) faces downwards for passage through the floor.
