Embodiment Construction

[0063] now refer to figure 1 , shows in a view from the rear an apparatus for coating a substrate by high velocity flame spraying. The plant generally consists of the actual burner and the means of supplying the coating material to be melted and applied. From such as figure 1 It is evident from the illustration shown that the rear of the device has several connectors for the supply of the medium required to operate the burner, as well as for the connection of the pressure sensor and additionally for the connection of the igniter. It is understood that the number and arrangement of connectors may vary. In this example, connectors A1 to A9 are provided for the supply medium, i.e., A1 Liquid fuel, A2 Oxygen, A3 Oxygen, optional, A4 Nitrogen, A5 Gas fuel, A6 Cooling water in, A7 Cooling water out, A8 Powder, A9 powder. It will of course be understood that instead of the above-listed media other liquid or gaseous media may be supplied via the connectors A1 to A7. Connector A10...

Abstract

Proposed is a device for coating substrates by means of high-velocity flame spraying. The device comprises a combustion chamber (4), a first fuel feeder (L1) for feeding a liquid or gaseous fuel as well as at least one gas feeder for feeding an oxidative gas. The devise comprises furthermore a second fuel feeder (L5) for feeding a liquid or gaseous fuel as well as at least one further gas feeder for feeding a gas. Both the first gas feeder and the two fuel feeders (L1, L5) port into a common combustion chamber (4). In addition, means 24, 28 are provided for independent control of the fuel feed into the two fuel feeders (L1, L5).

Description

technical field [0001] The invention relates to an apparatus for coating substrates by high velocity flame spraying as stated in the preamble of claim 1 . Background technique [0002] Devices of the type discussed are known in many different embodiments and are used for many different purposes. For example, they are used to surface coat a large variety of substrates to render them resistant to temperature and / or abrasion and / or abrasion and / or chemical attack. [0003] Devices fueled by gas, as well as devices fueled by liquid fuel, are known from the prior art, common devices generally having at least one connection for fuel and another connection for oxidizing gas. In particular liquid fueled devices may have a further connection for compressed air. However, all these known devices have the disadvantage that their range of application is limited. [0004] A head for high-velocity flame spraying of powdered materials is described in German patent DE 44 29 142 A1. The f...
