Description

DESCRIPTION

biomass stove

TECHNIQUE SECTOR

The present invention refers to a biomass stove, such as pellets, which has the particularity that, in addition to being a means of heating for a home, premises or any room deemed convenient, it incorporates a kitchen oven that allows take advantage of the heat generated in the combustion of biomass for cooking food.

The stove of the invention thus constitutes a means of heating rooms and cooking food that does not require any type of electrical supply.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, different biomass stoves are known that essentially incorporate a metal body or casing configured to radiate the heat released from combustion, a product feed hopper and at least one burner located in inside the combustion chamber.

In some cases, these stoves can incorporate a tempered glass window that allows the flame to be seen inside the stove. This window is also integrated into a door that allows access to the combustion zone, in such a way that the user can introduce the biomass at their convenience.

However, there are no known biomass stoves that allow the additional function of cooking as if it were a biomass oven.

EXPLANATION OF THE INVENTION

The biomass stove that is recommended comes to fill the previously described technical gap, based on a simple but highly effective solution.

For this, starting from the conventional structuring of a biomass stove, in which a metallic casing participates, in which a combustion chamber for the pellets or biomass is defined, which is accessed through a front door, a chamber that will incorporate an upper smoke outlet, as well as one or more intakes. air, including one or more valves for regulating the flow of gases and consequently the speed of combustion and/or turning it off, the invention focuses its characteristics on the fact that above the biomass combustion chamber a additional chamber in oven functions, which will incorporate a front access door with its corresponding tempered glass window.

In this way, part of the heat generated by the stove itself in the combustion of biomass can be used for cooking food in the chamber that functions as an oven, so that the temperature in said oven can be regulated by regulating the flow of air entering the combustion chamber (draught), through the corresponding manual regulation valves.

In this way, a multifunctional stove is achieved that allows the heat generated in the combustion of biomass to be used not only to heat the room in which it is located, but also to be able to cook food, thus improving thermal performance, all without the need for any type of electrical dependency.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a drawing is attached as an integral part of said description, in which For illustrative and non-limiting purposes, the following has been represented:

Figure 1.- Shows a perspective view of a biomass stove made in accordance with the object of the present invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the stove (1) of the invention is It is made up of a casing (2), essentially prismatic-rectangular, of a metallic nature or made of a thermally conductive material, on whose upper base (3) a chimney is established, not visible in the figure.

As a purely exemplary way, the casing could have dimensions of the order of 550x540x950mm (width/depth/height), with a chimney with a diameter of the order of 120mm, and a weight of the order of 108Kg.

In the casing (2) a biomass combustion chamber is defined, which is accessed through the corresponding door (4) assisted by its handle (5) and equipped with a tempered glass window (6), a chamber that By way of example, it could have a capacity of around 12 kg of pellets.

The casing (2), as is conventional, will include air intakes (7) assisted by flow regulation valves through which the flow of air (oxidizer) can be regulated inside the combustion chamber and consequently the combustion rate of the biomass, as well as the shutdown of said combustion due to lack of oxidizer, all of which will be done manually through an actuation control associated with said gas flow control valve.

Well then, in accordance with the invention, it has been provided that an additional chamber be established above the biomass combustion chamber as an oven, also made of thermally conductive material, preferably metal, which is accessed through a second hatch or door (4') on the front of the casing (2), assisted by its handle (5') and equipped with a tempered glass window (6').

From this structuring it is possible to increase the thermal efficiency of biomass combustion, up to values of the order of 82%, with a power between 4 and 8 kW with a biomass consumption between 0.9 and 1.9 Kg/h, although these values are merely exemplary, since they could vary depending on the final dimensions in which the stove is obtained, all with a completely independent device that does not require electricity.

Claims (1)

1a.- Biomass stove, which being of the type that includes a casing (2), essentially prismatic-rectangular, of a metallic nature or obtained from a thermal conductive material, on whose upper base (3) a chimney is established, including an internal biomass combustion chamber, which is accessed through the corresponding door (4) assisted by its handle (5) and equipped with a tempered glass window (6), a chamber that is connected to at least one intake of air (7) assisted by at least one manually operated flow regulation valve, characterized in that an additional chamber for oven functions is established above the biomass combustion chamber, made of thermal conductive material, to which It is accessed through a second hatch or door (4') on the front of the casing (2), assisted by its corresponding handle (5') and equipped with a tempered glass window (6').
