Description

Hydronic bowl in the oven

The invention relates to a masonry furnace bowl, combined with a novel solution for the transfer of heat generated by the oven buffer tank.

In the prior art market pönttöuuneissa problem was that the water circulation pipes could not be put inside the bowl in the oven, as they should have been placed in a fume ducts so that the smoke would cause corrosion of pipes, nokeaisi them and complicate the passage of smoke and cleaning the channels. Likewise, the tubes could not be placed in the oven with masonry structures, because of the greater thermal expansion of the metal would break masonry structures.

The idea behind the invention is how the heat generated by the furnace bowl can be transferred as efficiently as possible the water heater and the heat transfer solution can fit well inside the furnace.

The basic idea of ​​the invention is the following: on the inside of the furnace masonry furnace installed welded steel yläpalotila and the flue duct and installed on both sides of the metal lämmönsiirtokierukat, which circulates fluid, which transfers the heat to the water heater. Heat is transferred from a steel yläpalotilasta radiated and conducted coils. Outside of the shell role is primarily to prevent excessive transfer of heat from the room air.

More specifically, the oven according to the invention is characterized by what is disclosed in the characterizing part of claim 1.

In the following the invention is described in more detail with reference to the accompanying drawings, in which Section drawings of a furnace structure according to the invention.

Drawings are:

Yläpalotila the oven and down to the descending flue duct is welded to the sheet metal as a single element (1), which is calculated on the masonry of the furnace and the flue duct (2). The element is eg. Made of stainless steel or other highly heat-resistant metal. Yläpalotilassa temperature of the oven up to about 900 ° C, and the steel melting point of 1538 degrees. The element does not give any masonry structure, when a metal heat expansion will not cause any problems. It rests on the masonry of the fireplace and held in place by the flaps, which are welded to the element alaosaani 3). Between the element and the masonry can be fitted glass fiber ribbon or other highly heat-resistant tape that seals the junction (4). The liquid circulation is arranged so that both sides of the element mounted on bent for the laying of pipe coils (5), in which the circulating liquid element emits heat radiation inside the furnace and the air conduction along. Pipes are eg. Copper or acid-resistant steel. Smoke does not reach the soot water circulation pipes as it flows through a closed system and leaves the furnace rear flue pipe. Coils is a vent valves (6), the liquid will fill the tubes completely. The laying of pipes attached to the furnace wall by fasteners (7) that allow vertical lämpölaajenemisliikkeen. Also, vent valves are able to move vertically within the holes in the earth oven. The holes are available for the installed onto the insulated element. Helices lead pipes (8) water heater. The liquid circulation of an electric pump and it can be started manually or by the automatic oven thermometer sensor. The charger must be big enough and well insulated that warm water is enough to smoothly use.

The oven features have been improved as follows:

Element coils and the inner walls of the furnace item installed in the laying of a reflective surface of an insulation (9), which prevents the outer cover from heating up too much. This oven can be more suitable for low-energy house, because the oven does not heat the air in the room too. The furnace is mounted on top of a hard mineral wool insulation (10), which isolates the upper part. Alternatively, the underside of the top cover may be a reflective surface for the insulation. In addition, the furnace can be installed on the outer wall of the valves (11), whereby heat may be removed from the air in the room.

Oven conventional components are:

The furnace (12), the soot door (13), connection to the chimney (14), (tin) outer shell (15).

The invention can be applied to a wide range of high pystyuuneissa.

Vesikiertokierukoiden transfer tubes can be put in to go off the furnace through the top cover, thus avoiding the need to install the vent and under the floor to make awkward pipe installations. Pipes must, of course, to isolate the well to the tank, as in the circulating fluid is about 100 degrees. The piping must be installed in kiehumisventtiili because the pump stops, the piping liquid may boil. In this case, the pressure is released e.g. sewerage system or to the atmosphere, the boiling fluid pressure to open the valve. Piping must then re-filled and attached to it by means of the tap.
