Patented in the German Empire on February 7, 1911.

The invention relates to a heating method based on the use of catalytic Body is based.

Devices have already been described which are used to generate higher temperatures serve for heating purposes using catalysis. In the facilities used for this purpose, the catalytic Mass flowed through by a gas-air mixture, ίο There is either a considerable pressure necessary to force the gas and the combustion air through the entire mass, or the mass must be piled up very loosely, including large amounts of the catalytically active Substances are required.

According to the invention, these drawbacks are countered by only using the gas without Air admixture is passed through the mass, so that the catalytic processes on the outside of the burner or radiator, from the atmospheric air play surrounded catalytic mass.

The burners used to carry out the process can be perforated in the manner of a sieve or consist of gas-permeable material and carry the catalytic on the outer surface Dimensions.

As a result of this process, the gas can be used at the usual pressures Setting up the burner is much easier, and a thin layer is enough catalytically active mass.

In the drawing, some devices are illustrated, by means of which the method can be executed.

Fig. Ι and 2 show in vertical cross section and in a view or longitudinal section one for living spaces ο. Like. Certain gas furnace with the new burner device is provided.

Fig. 3 shows a number arranged on a common gas supply pipe Burner with a circular cross-section.

Fig. 4 shows in a vertical section the application of the method in one Stove arranged burners.

FIGS. 5 and 6 show the application of the method for heating a tubular boiler.

In the gas furnace shown in FIGS. 1 and 2, α is the housing perforated to facilitate the escape of heat, b is the actual burner into which the gas supply pipe c opens. The plate d of the burner is sieve-like, provided f with a large number of perforations or consists of gas-permeable material and carries on the outside of the catalytic mass m. Are α in the bottom of the housing holes i provided for the admission of combustion air ν by the plate against the burner plate d is directed, g is a glass plate, which also serves as a closure of the peephole.

The gas fed through the pipe c enters the space b and passes from there through the perforations f of the burner plate d to the catalytic mass m and here, with the mediation of the air flowing in through i, for combustion; the products of combustion are drawn off through space e and pipe h to the chimney.

In Fig. 3 three burners are shown, which consist of burner tubes provided with perforations f ■ d , on the outer wall

dung the catalytic mass m is attached. The gas passes through tube c into the interior b of the burner, then through the perforations f to the outside to the catalytic mass and burns here with the mediation of the air entering in the direction of the arrows. The combustion products reach the collecting space t and from there to the discharge pipe k. Fig. 4 shows the use of the burner ίο in a cooker. Here the burners consist of the spherical surfaces d provided with holes f, on the outside of which the catalytic mass m is located. The air enters through the holes i in the wall of the housing α. The hotplate η is heated by the resulting heat. FIGS. 5 and 6 finally show the application of the method for the purpose of heating tubular boilers. From the common gas supply pipe c from branch pipes χ, which are led into the smoke pipes y of the boiler. The tubes χ are also provided with perforations and the catalytic mass is attached to the outside of the tubes χ. In this case, the necessary combustion air must be obtained by pulling the chimney ζ or by a fan. The activation of all of the heating devices shown in the drawing takes place in such a way that gas is passed through the pipe c into the space b of the burner d, which then passes through the channels f to the outside, mixes with the atmospheric air and on the catalyst m comes to combustion. This gradually turns it glowing. The hot combustion products are collected in a suitable manner, for example according to FIG. 1 in the room e or according to FIG. 3 in the tube t, according to FIG. 4 in the interior of the housing a, n, according to FIG. 5 through the smoke tubes y, and are thereby made usable for the desired purpose in order to then be diverted into the chimney. Since the higher their temperature, the faster and more effective the catalytic substances are, when starting up the procedure can also be carried out in a known manner in which the gas flowing out through the perforations or nozzles of the burner is ignited and the flame is kept for as long (for example 12 to 1 minute) until the catalyst glows, after which the gas flow is shut off, whereby the flame is extinguished, and then the gas flow is restored. As long as the gas flow exists, the catalyst remains glowing brightly over its entire surface. Sponsorship τ claims: 1.Heating process using gaseous fuels and catalytically active bodies, characterized in that only the gaseous fuel through the catalytic Mass is passed and is brought to combustion by means of the air on the other side of the mass. 2. Burner to carry out the procedure according to claim 1, characterized in that the burners are perforated like a sieve or consist of gas-permeable material and on its outer wall the carry catalytic mass.
