Description

DETAILED DESCRIPTION OF THE INVENTION The present invention consists of a surface-burning radiant plate or panel made of a refractory material, such as bonded refractory ceramic fibers or solid refractories, which plate or panel has a Porous or having passageways to allow the passage of a mixture of gas and air for combustion, this board or panel can be used for space heating and other domestic or industrial purposes. This invention relates to a type of gas burner that is designed to produce incandescent heat as a radiant heater.

Conventionally, such radiant panels are mounted on top of a metal casing, and the interior of the casing is supplied with a gas or a mixture of gas and air, which passes through a plate or panel forming a facade or enclosure for the casing. However, it was common for it to burn on its surface.

However, metal casings are relatively expensive, especially if special internal shaping is required, and also involve operational difficulties, such as differential expansion with refractory ceramic components. There is.

According to the invention, a casing for supporting a radiant panel burner is made from a refractory ceramic material in the form of an open-topped box.

A refractory radiant panel can be mounted as a lid over such a refractory box and coated with refractory mortar or a refractory mortar to form a radiant panel burner composed entirely of refractory ceramic material. It can be fixed by refractory cement or adhesive. Such a complete ceramic unit constitutes one feature of the invention.

Optionally, glass tape or other fire-resistant fiber tape bonded by adhesive to increase the strength of the joint or form the joint on its own;
It may be wrapped to cover the joint between the panel and the housing.

Boxes of simple shape can be manufactured very economically by dry or semi-dry pressing of suitable ceramic materials, such as fireclay, and specific internal shapes can be It can be provided by casting or by fixing separately made parts inside the box with refractory cement, mortar, etc.

The internal shape of the refractory box shall be such that it deflects or guides the flow of the gas-air mixture supplied as a gas with air, or causes mixing of the mixture. I can do it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings showing embodiments thereof.

As is clear from the figure, the housing consists of a box 1 with a beveled edge 2, which receives a layer of cement, on which a burner plate 3 is embedded. A glass fiber tape 4 bonded with a fire-resistant adhesive completes the joint between the edge 2 and the burner plate 3. Gas and air enter through openings 5 in the bench lily or other gas or gas-air mixture supply fittings and are guided by baffle plates 6 fixed in place. There is.

A mounting groove 7 is provided for mounting the assembly as a whole.

The burner plate is generally of the well-known multi-pyramid shape, with gas and air passages provided in the halves where the corners of the pyramid meet and along the grooves between each pair of faces. (See Figures 5 and 6).

Claims (1)

[Claims] 1. A radiant refractory panel adapted to pass combustion gases and air is mounted on a ceramic box-shaped casing open at the top, adapted to admit air and combustion gases or a mixture thereof. the panel is made of adhesive-bonded glass fibers wrapped to cover the joint between it and the casing; or
A gas burner for a surface combustion heater, characterized in that the panel and the casing are fixed to each other with another fire-resistant fiber tape so that there is no possibility of a difference in thermal expansion between the panel and the casing.
