DE2445673A1 - Fireplace-mounted boiler - has steel water jacket and water cooled tubular grids - Google Patents

Abstract

The boiler consists of a steel water jacket, and has water-cooled tubular grids, to carry the fuel. Similar transverse boiler tubes are positioned in the upper boiler area. The flue gases are fed into a channel, extending at the front over the complete width of the fireplate. The heated water is fed via a circulation pump, into a heating system, and then to consumers, or directly to the consumers. Any surplus heat is stored by the heated water in a storage tank.

Description

"Fireplace - Boiler The invention relates to a fireplace - heating boiler, which is particularly suitable for burning objects in the to make more effective use of the open fireplace.

The aminfeer is well known. Its origin lies in the open Hearth fire. Modern chimneys are made of fireclay bricks, with the combustion material Burn on grids that have been cooled by air. Wood is predominantly used as the combustion material taken. During the combustion process, the fireclay bricks are heated, see above that the heat of combustion and part of the radiated heat from the firebricks is fed into the room.

A major disadvantage here is that the illuminated area is a absorbs high levels of radiant heat and the shady sides remain in the cold zone.

The efficiency of these fireplaces is very low, approx. 15-20 ffi ). For example, if 50 kg of wood are burned at an efficiency of 15% would this mean that a room 50 Kg. x 3,700 Kcal in a Efficiency of 15 6% 2?.? 5o Kcal of heat can be supplied.

Despite this low output, open fireplaces very often find their way out For reasons of decoration, but also for reasons of independence, it is used again and again.

The invention has set itself the task of addressing the disadvantages of the known Avoid open fireplaces and develop a fireplace boiler which in is able to make better use of the heat released during combustion and thus supplying the temperature to several rooms at the same time.

To solve this problem, the invention proposes a fireplace boiler before, which consists of a water-bearing steel jacket. In the water-bearing Steel casing are water-bearing grates for the contact surface of the combustion material arranged. Water-bearing cross boilers are arranged in the upper zone. The smoke gases are led into a flue gas duct, which is in front of its entire front width the chimney is arranged. During the combustion of the combustion material are Now the water-cooled grids are able to absorb the temperature. Likewise is the water-bearing jacket and the water-bearing cross boilers located in it able to absorb the heat released during combustion. The combustion gases are drawn off into the flue gas duct in the upper burn and from there into the flue gas chimney fed. That through the Water heated by combustion is now used either fed into an existing boiler system by means of a circulation pump and forwarded from here to the heat consumer, or directly by means of a circulation pump to the heat consumer.

The advantage of this chimney-boiler arrangement is that The heat is fed to the chimney boiler water through the cooled heating gases and thus a high efficiency of 85% is achieved.

Fireclay bricks no longer need to be bricked up.

A great advantage is the uniform temperature in all rooms through controlled delivery of the heat generator.

For heat storage, a night or transitional operation can be used well insulated volume of water to be heated so that the stored heat during the night time can be consumed.

As an example for the different degrees of efficiency should be given 50 kg of wood a. 3,700 Kcal = 185,000 Kcal efficiency 85% - 157,250 Kcal Efficiency 15% = 27,750 Kcal so a heat gain of 129,500 Kcal at 50 kg. wood The invention is described in detail below with the aid of a representation of characters explained: Figure 1 shows the fireplace boiler in its front view, according to of the invention Figure 2 shows a side section through the fireplace boiler with hot water heat storage connected behind it, according to the invention figure 3 shows the fireplace boiler in its view from above, according to the invention Water-bearing steel jacket no.1 consists of a folded sheet steel with the bottom Water-cooled grids No. 2 lying as a support surface, as well as those in the upper quarter located water-cooled cross boiler no.3. On its front broadside is a Flue gas collector No. 4 welded to a flue pipe socket No. 5. Around the steel jacket No. 1 is another steel jacket No. 6 welded, and indeed in such a way that a cavity is created for water supply. Up is the inner steel jacket # 1 with a Cover plate no.7 welded, the outer steel jacket no. 6 is with a cover plate No.8 welded. The closed container is filled with water which is warmed up when heated.

The heated water is through the two pipe sockets No. 9 and Nur. 10 either the storage tank 11 or through shut-off valves, optionally switchable, fed directly to heat consumer no.12.
