     5-DESCRIPTION BOILER WITH HOUSE OF COMBUSTION WITH DOUBLE HEAT EXCHANGE SURFACE SECTOR OF THE TECHNIQUE The present invention belongs to the heating sector through the heating of 10 water by means of fuel boilers. The main object of the present invention is a boiler that has a home with a double heat exchange surface, one of which has been achieved with a linear system of inner hollow tubes where the water recirculates and the other surface is the same Household chamber 15, achieving double performance compared to a conventional boiler. BACKGROUND OF THE INVENTION 20 Boiler, in heating systems, is the device in which a bearer, usually water, is heated by means of a fuel or electrical resistance, which will then be distributed by the emitters through a network of pipes. A heating boiler consists of a home, where the fuel is burned, and an exchanger where the heat produced by combustion is transmitted to the heat carrier, which takes it to the emitters or terminal elements. When the use of a burner (for fluid fuels) is necessary, the boiler and burner assembly is called a generator. Boilers based on the type of fuel may be fluid fuel boilers and solid fuel boilers. Within the boilers of fluid fuel are the condensing boilers (whose main fuel is natural gas) and with the advantage of greater performance but the temperature reached by the heat carrier is lower, so it requires larger emitters (larger radiators) or low temperature emission systems (irradiating floors). Within the boilers of fluid fuel it is also worth mentioning the boilers with atmospheric burner, which are aimed at the use of specific atmospheric gases. Its operation is based on the Venturi effect; the injectors supply the 2Pressure fuel there then by Venturi produces air aspiration in the appropriate proportion and when mixed burns in the burners, giving rise to small flames inside the exchanger. Solid fuel boilers are characterized by using fuels that leave a residue when the combustion known as ash occurs, hence many boilers are divided into two compartments, the upper or brazier, also known as the home, and the lower or ashtray where deposit the residue of the burning of fuel. In the ashtray there is usually an air inlet that is what causes combustion to occur in the brazier where there is a smoke outlet or chimney that by thermal draft 10 goes outside. This air outlet causes a lack of pressure in the home that causes the aspiration of the air for combustion, the regulation of air intake can be adjusted from the ashtray hatch that usually have a butterfly to open more or less the entrance of air to the ashtray. In these boilers, the exchanger is the envelope, which has a double wall between whose 15 layers the heat carrier circulates. In some, even the separation grid between the brazier and the ashtray consists of a series of pipes, through which the heat carrier also circulates. EXPLANATION OF THE INVENTION 20 The boiler with combustion hearth with double heat exchange surface object of the present invention whose heat carrier is water, has a greater heat exchange surface, greater performance and a greater ease in carrying out the cleaning with smaller dimensions. The main advantages of the invention could be summarized as follows: • The boiler allows burners for solid or fluid fuel to be coupled • Increased heat exchange thanks to its interior pipe system in the home creating an additional exchange surface in addition to the household wrap itself . • Cleaning the boiler especially with solid fuels is more accessible 30 because all the ash falls by gravity and is driven to the bottom of the boiler or ashtray where there is an automatic collection. 35 • Increased performance with respect to a conventional boiler thanks to its double heat exchange surface and the system for the reconduction of fumes from combustion. 3The boiler with combustion hearth with double heat exchange surface object of the invention comprises an internal structure of aligned pipes arranged in two symmetrical rows and parallel to the interior walls of the hearth with inclination angle to facilitate the flow of water when it occurs The warm-up. 5 These pipes are located in the inner home welded against the walls at both ends of the pipes and their number will depend on the length of the home with constant distance between them. At the lower end they are welded against the inner plate of the home that has an angle of inclination with the horizontal. 10 The tube rises from the lower zone and approximately half its length makes a turn until it reaches its upper end where it is welded with the same inner plate of the home producing a collector to collect all the tubes. This inner chamber is surrounded by a layer of water, which is the medium used as a heat carrier and is responsible for transmitting the increase in ro to the heating circuit through the outlet pipe. The interior home has two openings in the upper left and right rear area through which the fumes from the combustion exit through a conduit of upper triangular section connected by a vertical cylindrical tube welded to another lower longitudinal conduit similar to the upper one that carries the fumes to the rear flue collection chamber 20 following a path along the side of the boiler making a double turn that allows more heat to be transferred to the water, significantly increasing the boiler's performance. BRIEF DESCRIPTION OF THE DRAWINGS 25 To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is included as an integral part of said description, where it is illustrative and not limiting, the following has been represented: Figure 1.- Shows a perspective view of the preferred embodiment, the poly fuel boiler (fluid or solid) object of the present invention. Figure 2.- Shows a perspective cut of the interior of the preferred embodiment with the water shaded by the circulation area. 4Figure 3.- Shows a front section of the poly fuel boiler (fluid or solid) object of the present invention where the water path in the inner chambers of the preferred embodiment is appreciated. Figure 4.- It shows a side section of the poly fuel boiler object of the present invention where the exchanger tube system according to preferred embodiment is shown. Figure 5.- Shows a perspective cut of the rear part of the poly fuel boiler object of the present invention where the flue outlet of the boiler and its subsequent collection in the smoke box can be seen. PREFERRED EMBODIMENT OF THE INVENTION The boiler with combustion hearth with double heat exchange surface object of the present invention in its preferred embodiment comprises an inner chamber or household (1) where the heat exchanger tubes (2) arranged in two are located 15 symmetrical rows parallel to the interior walls of the home and welded at its base and at its cusp to said walls (3) and with curved angles (4) parallel to the inclination of the interior sheet of the home about two thirds of its length total. Wrapping home is the second chamber (5) where the bearer is placed, which in this case will be the water, connected to the heat exchanger tubes (2) and with an outlet through the top part through the discharge tube (6 ) connecting to the outdoor heating circuit. The combustion flue is exited through two windows or openings in the walls of the home (7) in the upper rear area of the home (1) that conduct the fumes through two lateral pipes (8) until reaching the vertical pipe (9) follow the longitudinal lower tunnel 25 (10) to the rear smoke collection chamber (11). Once in the smoke collection chamber (11), the smoke flows through the chimney hole (12) to the external smoke outlet circuit of the installation. The interior walls of the home (1) have a sufficient slope to favor the fall of the solid residues of combustion to the ashtray area (13) which, by means of a screwed placket 30 (14), allows its access and cleaning from the outside. The boiler has an inlet for the bearer in the lower rear part (15) composed of a tube with a welded flange. The boiler with combustion hearth with double heat exchange surface, in the upper front part, has two symmetrical accesses (16) according to the longitudinal plane for cleaning the vertical tubes (9). 5
