Abstract

A device for an insulation plate (1) for an exhaust pipe (2) from a combustion engine, the insulation plate (1) comprising, closest to the exhaust pipe (2), a stainless cloth (4) provided with a mat (6) of ceramic fibre onto which an encapsulated mat (8) of microporous ceramic material is disposed.

Description

INSULATION PLATE FOR AN EXHAUST PIPE FROM A COMBUSTION ENGINE
This invention relates to an insulation plate for an exhaust pipe from a combustion engine. More particularly, it relates to an insulation plate for an exhaust pipe from a combustion engine, the insulation plate comprising, closest to the exhaust pipe, a stainless cloth. At the outside thereof relative to the exhaust pipe, the stainless cloth is provided with a mat of ceramic fibres onto which an encapsulated mat of microporous ceramic material is disposed. Along its edge portions, the insulation plate is provided with attachment features arranged in a manner allowing them to be connected to attachment features belonging to an adjacent insulation plate, the attachment features enclosing an insulation string disposed on the outside of the edge portions of two adjacent insulation plates .
In this connection, the term combustion engine implies all engines utilizing energy from an internal combustion process, for example a piston engine or a gas turbine.
Owing to their relatively large surfaces and high temperatures, exhaust pipes from combustion engines may emit consid- erable amounts of heat to the surroundings . In the operation of stationary, encapsulated gas turbines, this heat may constitute a considerable operational problem given that the temperature around the gas turbine may be high enough to dam- age instruments, for example.
According to prior art, exhaust pipes of this kind are often insulated with rock wool located in a bag-like encapsulation of fibreglass cloth. The insulation mats are connected to the exhaust pipes, for example by means of through-going pins or by means of surrounding wire. Normally, the insulation mats are detachable .
The recommended maximum operating temperature for the fibre- glass cloth is only insignificantly higher than the surface temperature that may occur in exhaust pipes of this kind. Therefore, the fibreglass cloth ages relatively quickly, while at the same time the binding agent of the rock wool seems to evaporate .
During dismantling of prior art insulation mats that have been in operation for a period of time, it is therefore com- mon for the part of the fibreglass cloth having been in contact with the exhaust pipe, to break up during the dismantling work; and for rock wool having lost its binder, to sprinkle out in the form of a powder-like material. If the damaged insulation mats are remounted, their insulating abil- ity will be reduced.
It is evident that insulation mats of this kind constitute an environmental problem during maintenance works .
Due to the large surface of the rock wool fibres, the above- mentioned insulation mats absorb considerable amounts of fuel or lubricating oil should a leakage occur. Experience goes to show that it is very difficult to extinguish a fire in, for example, fuel-saturated rock wool mats.
The object of the invention is to remedy or reduce at least one of the disadvantages of the prior art.
The object is achieved in accordance with the invention and by means of the features specified in the description below and in the subsequent claims.
According to the invention, an insulation plate for an exhaust pipe from a combustion engine is formed in such a way that the insulation plate comprises, closest to the exhaust pipe, a stainless cloth. At the outside thereof relative to the exhaust pipe, the stainless cloth is provided with a mat of ceramic fibres onto which preferably an encapsulated mat of microporous ceramic material is disposed.
Advantageously, the stainless cloth may form the reinforcement in a silicon-based cloth.
Typically, the mat of ceramic fibres is formed in a non-woven design. Generally, the ceramic fibres may be comprised of silicon dioxide, Siθ2, which can be subjected to temperatures up to 1100 0C. A 3 mm thick mat, which is marketed under the trade mark Insulfax by Bugges AS, 2021 Skedsmokorset, Norway, has proven suitable for the purpose.
The microporous, preferably encapsulated, mat of ceramic material may be formed into layers and may constitute a sub- stantial portion of the heat-insulating material of the insulation plate. A microporous mat from Bugges AS, which is marketed under the trade mark Microtherm Q-panel WR, is suitable for the purpose. The fibre layers in a mat comprising silicon dioxide - SiO2, titanium dioxide - TiO2, and silicon oxide - SiO, may withstand temperatures above 1000 0C. The encapsulation comprises a ceramic cloth.
It is advantageous to provide the outside of the insulation plate with a protective cloth. It is appropriate, for reasons of cost, to use a silicon-impregnated fibreglass cloth. A cloth of this kind provides sufficient heat resistance relative to the temperatures occurring on the outside of the insulation plate.
The stainless cloth and the silicon-impregnated fibreglass cloth are marketed by several suppliers, including Bugges AS.
Preferably, the stainless cloth encloses the edge portions of the insulation plate, the different cloths of the insulation plate being interconnected by means of stitching in a manner known per se.
The insulation plate is provided, at least along its edge portions, with attachment features arranged in a manner allowing them to be connected to attachment features belonging to an adjacent insulation plate.
Advantageously, the attachment features may be comprised of a folded cloth sewn onto the external protective cloth along the edge portions of the insulation plate. At suitable intervals , the folded cloth is provided with through-going openings for the tying together thereof, for example by means of a seizing wire.
If adjacent insulation plates do not bear perfectly against each other so as to form a gap between them, it is appropriate to place an insulation string over the edge portions of the insulation plates to prevent heat from dissipating through the gap. Typically, the insulation string is constructed in the same manner as that of the insulation plate, but normally it is not provided with attachment features . The attachment features of the insulation plate enclose an insulation string disposed on the outside of the edge portions of two adjacent insulation plates so as to press the insulation string against the edge portions.
The insulation plate according to the invention does not absorb moisture and thereby not inflammable liquids either. Normally, the overall height thereof is substantially smaller than that of prior art insulation mats, and it resists the prevailing temperatures by a good margin.
Hereinafter, a non-limiting example of a preferred embodiment is described and depicted in the accompanying drawing, in which:
Figure 1 schematically shows, in section, insulation plates according to the invention mounted on a hot surface.
In the drawing, reference numeral 1 denotes an insulation plate disposed on a hot surface 2, typically in the form an exhaust pipe from a combustion engine (not shown) .
As viewed outwards from the hot surface 2 , the insulation plate 1 comprises a stainless cloth 4, a fibre mat 6 and a mat 8, which preferably is encapsulated, of microporous ceramic material .
A protective cloth 10 of silicon-impregnated fibreglass is arranged on the outside of the insulation mat 1. The materials 4, 6, 8 and 10 incorporated in the insulation mat 1 are identified in the general part of the description and will not be described in any further detail.
By having folded the stainless cloth 4 up along the edge portions 12 and having connected cloth 4 to the protective cloth 10 on the outwardly-facing side of the insulation plate 1, the stainless cloth .4 encloses the edge portions 12 of the insulation plate 1.
Along its edge portions 12, the insulation plate 1 is provided with attachment features 14 in the form of a folded cloth sewn onto the protective cloth 10. By means of a seizing wire 16 extending within through-going openings 18, the folded cloth 14 is connected to attachment features 14 ' belonging to an adjacent insulation plate 1.
In figure 1, the insulation plates 1 are separated by a smaller distance, whereby a gap 20 is formed between the edge portions 12 of the respective insulation plates 1.
An insulation string 22 is disposed on the outside of said edge portions 12 so as to substantially prevent heat from dissipating through the gap 20.
The insulation string 22 is constructed in a manner corresponding to that of the insulation plate 1, with a stainless cloth 4 enclosing an encapsulated mat 8.
The folded cloth 14 encloses the insulation string 22 so as to press it in a sealing manner against the edge portions 12.
