Abstract
ABSTRACT
A description is given of an apparatus for utilising the waste heat of exhaust gases, wherein the exhaust gases reach a chimney from the combustion region of the furnace through a coil of pipe, and the coil of pipe is composed of pieces of pipe (1) of quadrangular cross-section, and forms a seating- or reclining arrangement.
(Fig. 1)
A description is given of an apparatus for utilising the waste heat of exhaust gases, wherein the exhaust gases reach a chimney from the combustion region of the furnace through a coil of pipe, and the coil of pipe is composed of pieces of pipe (1) of quadrangular cross-section, and forms a seating- or reclining arrangement.

Description
20360~
It is known pratice (see DE-OS 38 06 790 and DE-OS
36 00 982~ to distribute heat-radiating walls inside living quarters. When a gas passes through these walls, heated air is used rather than waste gas.
s Various problems are encountered with the concept of using the waste gases coming from a fi ~ e in order to heat dividing walls distributed in a living quarter.
If waste gas is to be conducted out of the furnace into the surrounding space and then back into the chimney, there has to be a difference in pressure for this to happen, and this is not normally achieved by the chimney itself. Therefore, a proposal has already been made (compare AT-PS 359 695), to remove the waste gas by suction using a ventilator. This solution is unsatisfactory because a ventilator is expensi~e in constructional terms, noisy and prone to malfunctions.
Using the waste gases directly in order to heat units disposed outside the actual furnace is also problematic because the waste gas should not be below 250C in temperature at the entrance to the chimney, so that the temperature does not fall below 130C anywhere in the chimney.
Insofar as waste gases have hitherto been used to radiate heat outside the actual region of the furnace, in consideration of the problems outlined, there have 2a~60~
been superstructures to the actual fireplace, such as for example in AT-PS 343 317. These superstructures can also take the form of a bench for reclining on or seats.
The aim of the invention is to make it easy for the architect to provide pieces of apparatus for utilising waste gases, the pieces of apparatus being distributed in the room. This is solve~ by the apparatus being designed as a coil of pipe extending from the side of the furnace, and composed of pieces of pipe of quadrangular cross-section.
Particularly if the pieces of pipe are fire-clay pipes such as are normally used for chimney manufacture, they store heat so well that the temperature at the entrance to the chimney can be kept at 250C. If a lining of tiles or bricks is provided, any kind of structure can be made of these fire-clay pipes.
The quadrangular cross-section of the pipes permits optimum utilisation to be made of the space available for conducting the waste gases, so that the flow resistance can be kept as low as possible so that no backwash or overflow of waste gases occurs. This is by no means self-evident, because the shape of the structures required for conducting the waste gases is 2~3~0l18 determined by the function thereof, for example, it can be the back rest of a bench, or reclining surface, or a low free-standing wall in the area.
The provision according to the invention gives the architect great freedom with designs for heat-radiating features of living areas. This is particularly applicable if pieces of pipe are also provided which are curved in the horizontal plane. There is thus considerable freedom with the structuring of the basic design, and the quadrangular cross-section of the pipes ensures that they are firmly joined together. The fact that the structures arising have vertical walls and horizontal contact surfaces does not restrict pratical implementation in any way.
There now follows a description of simple examples, given with the aid of the drawings, for use of the invention.
Figure 1 is an illustration of a first embodiment which is constructed by using straight pieces of pipe. Figure 2 illustrates a second embodiment wherein curved pieces of pipe are also used.
With the apparatus according to the invention, the waste gases issuing from the combustion chamber of a 2~3~0/18 tiled furnace 2 are conducted to the chimney 3 not directly, or simply by means of waste-gas flues arranged above the combustion apparatus. Instead, the waste gases flow, as shown by arrows in the drawing, through a coil of pipe 4 which extends from the side of the furnace through the living area.
In order to make the coil of pipe 4 sufficiently compact and statically loadable, it is composed of pieces of pipe 1 which are quadrangular cross-section.
The pieces of pipe 1 can be put together both at the open edges thereof, and also side by side. The transition of waste gases between two directly adjacent pieces of pipe is effected in such a way that the fronts of the pieces of pipe 1 are closed by panels 5 and the adjacent side walls of the pieces of pipe are provided with an opening 6.
When these kinds of pieces of pipe 1 are used as the structural element, it is possible for any kind of feature of a living area to be produced, especially if individual pieces of pipe 1, such as shown in Figure 2, are curved in the horizontal plane. The diversity of shapes which can be obtained is further increased if pieces of pipe of quadrangular cross-section are also used which form a pipe elbow. If elements such as these are a~ailable, the tiled furnace 2 itself can also be 20360~8 composed of pieces of pipe in the way disclosed in AT-PS 373 374, wherein, except at the region of the lateral openings, waste gases pass therethrough in the direction of their axes, wherein the corners of the heating flues extending across the combustion chamber are each formed by a pipe elbow.
