Description

Gas burner

The innovation relates to gas burners with a surface ⁿ irverbrennimgs radiation plate made of heat-resistant material, e.g. glued keratic fibers or a heat-resistant solid that is porous or is provided with channels for the passage of a fuel gas that burns on the top of the plate, which as Radiant heaters glow in order to heat an iiaum su or to fulfill other purposes in the household or in the industry.

So far it was common to have such radiation panels on To arrange metal housings, in the interior of which fuel gas or a Brenngasluftgemiscn was introduced through which the front or to flow through the plate forming the cover of the housing and to burn it on its upper side.

Metal housings are relatively expensive, especially if a special internal shape should be required, and difficulties may also arise during operation, for example due to the different thermal expansion of metal and heat-resistant ceramic components.

According to the innovation, a housing is train support a heat-resistant radiation plate of a burner in the form of a box made of heat-resistant ceramic material, which is open at the top educated.

Preferably the box is pressed.

A heat-resistant radiation plate can be placed as a lid on such a box and with a heat-resistant Mortar or cement or glue to form a radiant panel burner assembly that is completely consists of heat-resistant ceramic material. Such a complete Keraraik unit is a feature of the innovation.

alternatively, a ribbon of adhesive-impregnated fibers made of glass or other heat-resistant material can be wound around it be to cover the joint between the plate and the housing to increase the strength of the connection or to form the connection itself.

Simply shaped boxes can be made extremely economical by dry or semi-dry pressing a suitable Heat-resistant ceramic material, such as fireclay, can be produced, and special inner shapes can be made by pouring and / or separately manufactured components are created, which are loaded with heat-resistant cement, mortar or a reference mat in the boxes

are consolidated.

Due to the internal shape of the heat-resistant boxes deflecting or guiding the flow or mixing a mixture of fuel gas and air, which is supplied as an air-sucking gas, for example by a venturi injector or is supplied as a mixture of gas and air.

Further details, advantages and features of the innovation ( result from the following description and the drawing, to which reference is expressly made with regard to all details not described in the text. They show:
