GR1009064B - Individual low-temperature condensation boiler unit - Google Patents

Abstract

Novelty: an individual-use low-temperature condensation boiler is disclosed. Constitution: an integral exhausts heat exchanger 3 absorbing the exhaust-borne heat exiting from the flue 2, and separating lamellae (5,6) aiming at extending the course of the exhausts. The main cylinder-like body of the boiler 1 has adequate exhaust cutters (one made of steel 9 and four of cast iron 10), which cutters extend the course of the exhausts prior to their being exited from the flue 2. An adequate arrangement meant for the drainage of water produced by exhausts condensation. The exhausts are cooled up via the exchanger and get out, eventually, from the flue 7 at a temperature of 50 deg. thereabouts what signifies production of water which should be conducted out of the exchanger and stored up in a suited mode.

Description

ATOMIC UNIT LOW TEMPERATURE CONDENSING BOILER

DESCRIPTION

The invention refers to the construction of an individual low temperature condensing boiler unit. It is an innovative device that absorbs the heat of the flue gases which are liquefied in the condensing exchanger. The condensing boiler has been studied and designed for the most modern requirements in the field of heating. Intended for the production of hot water (up to 95 °C) in individual heating installations with oil or gas.

The condensing boiler has a higher degree of efficiency than the conventional boiler, because it also takes advantage of the heat of the exhaust gases, part of which is recovered through a specially designed exchanger, which is made of stainless steel, in which the cooling and condensation of the exhaust gases takes place.

In addition, the overall losses from the chimney and the walls of the condensing boiler are much smaller than those of a conventional boiler, due to the lower temperature (45-50°C) of its flue gases, while a conventional boiler discharges its flue gases with temperature 180-280°C. Thus, the condensing boiler achieves a significant reduction in fuel consumption compared to a conventional boiler, in any type of installation. Finally, one of the most important advantages of the condensing boiler is that it comes very close to the theoretical model of "perfect" combustion. Almost no "dangerous" pollutants such as CO (carbon monoxide) or NOx (nitrogen oxides) are produced. This has the effect of making them ideal, from an ecological point of view, for densely populated cities.

The main components of the device are the following:

> Main boiler body (1 )

> Chimney (2)

> Flue gas exchanger (3)

> Water pipes (4)

> Separator plates for alternator body (5)

> Alternator cover spacers (6)

> Chimney (7)

> Drainage (8)

> Steel chimney flue (9)

> Cast iron chimney flue (10)

These components as well as their assembly are given in the attached drawings which are as follows:

Drawing 4: Cast iron chimney flue.

Drawing 5: Steel chimney flue.

The individual low temperature condensing boiler unit has three (3) innovative features which require patenting and are the claims of the Patent.

The first feature is that it has an integrated flue gas heat exchanger (3) which absorbs the heat of the flue gases leaving the flue (2). During the route of the flue gases there are separating plates (5) and (6) with the aim of increasing the route. The cold water that returns from the bodies enters the exchanger from its lower part and through the water pipes (4) is channeled to the boiler (1). In this way, the energy efficiency increases due to the fact that there is a greater temperature difference between the cold water (when entering the exchanger) and the flue gases which finally exit the chimney (7).

A second innovative feature is that the main body of the boiler (1), which has a cylindrical shape, has appropriate flue gas cutters, one steel (9) and four cast iron (10) which increase the path of the flue gases before they exit the flue ( 2). The cutters have a suitable design so that the flue gases travel as long as possible inside the boiler and at the same time do not increase the draft required for the operation of the boiler.

A third innovative feature is that it has a suitable water drainage device (8) which is produced during the operation of the boiler due to the condensation of flue gases. The flue gases through the exchanger (3) are cooled and finally exit into the chimney (7) at a temperature of approximately 50 °C. The result is the production of water which must exit the exchanger and be properly drained.

Installation and start-up of the device is done by following simple procedures. The device is designed and manufactured in such a way that its use does not endanger users, when used under the conditions and for the intended purposes. It has sufficient mechanical strength and is designed to withstand the mechanical stresses that may occur in normal use.

Claims (3)

The cold water that returns from the bodies enters the exchanger from its lower part and through the water pipes (4) is channeled to the boiler (1). 2. Individual low temperature condensing boiler unit according to claim 1, which in the main body of the boiler (1) which has a cylindrical shape carries suitable flue gas cutters, one steel (9) and four cast iron (10) which increase the path of the flue gases before they exit the flue (2). The cutters have a suitable design so that the flue gases travel as long as possible inside the boiler and at the same time do not increase the draft required for the operation of the boiler. 3. Individual low-temperature condensing boiler unit according to claim 1, which has a suitable device for draining the water (8) produced during the operation of the boiler due to the condensation of flue gases. The flue gases through the exchanger (3) are cooled and finally exit into the chimney (7) at a temperature of approximately 50 °C. The result is the production of water which must exit the exchanger and be properly drained.
