Definitions

  • the present invention as expressed in the title of this specification, relates to a device for generating hot air by means of biomass combustion, which provides several advantages to the function for which it is intended, as well as novelty features which will be described in detail below, and which represents an improved alternative to the currently known systems serving the same purpose.
  • the object of the invention focuses on a device for generating hot air, which can be applied to the heating of industrial premises or large enclosures, and uses pellets and other types of biomass as fuel, essentially made up of a combustion chamber, a tubular heat-exchanger unit where the heat from the combustion gases is transferred to the air driven by a blower fan designed for this purpose, presenting the particular feature of being structurally configured so that said heat-exchanger unit, which is arranged behind the combustion chamber, is detachable and couples to the tubes vertically, thereby providing advantages of transport and assembly, extending the useful life of the device, generating less ash accumulation, ensuring easy cleaning, greater efficiency and lowering the costs of maintenance.
  • the field of application of the present invention falls within the industrial sector dedicated to the manufacturing of equipment and devices for generating hot air, particularly focused in the area of those that use biomass as fuel.
  • biomass is the most economical and environmentally friendly fuel because it generates energy savings ranging from 40-60% when compared to other fuels. It is therefore increasingly common to use devices which are powered by said fuels such as those generating hot air to heat large premises.
  • These devices are conventionally made up of, amongst other elements, auger feeders which move the biomass towards the burner of a combustion chamber from which the combustion gases are expelled to a heat-exchanger unit where heat transfer is achieved.
  • the essential problem involved with these devices is usually the difficulty encountered in detaching the tube assembly, which makes up the heat-exchanger unit, since it is normally designed as a single part, integrated on the combustion chamber, which implies difficulty in transport and assembly. Furthermore, said layout is usually arranged with the heat-exchanger unit tubes in horizontal position, which causes the accumulation of solids and ash inside said tubes, thus constituting a factor which impedes the optimal performance of the device making it necessary to clean the tubes periodically, which, moreover, is not an easy task.
  • Utility models under publication No. ES 1053357 and ES 1070424 consist of a hot air heating system fuelled by organic and industrial waste aimed at the heating of industrial and livestock buildings, where combustion gases heat an air fluid by means of a heat-exchanger unit, thereafter introducing this hot air into those buildings for their heating.
  • the patent under publication No. ES 2482215 relates to a biomass hot air device comprised by a set made up of a furnace, connecting tubes and a heat-exchanger combined with a turbine in order to drive the hot air into the industrial building.
  • the object of the present invention is to structurally configure said heat-exchanger so that it can be easily detachable and to improve the mentioned issues of cleaning and efficiency of the device by means of its layout as an independent element behind the combustion chamber and having the tubes in vertical position.
  • affixing the air supply blower fan to the closest end of the combustion gas outlet also favors an increased performance of the device.
  • the device for generating hot air by means of biomass combustion which the present invention proposes is configured as an innovation within its field of application, since according to its implementation, and in an exhaustive manner, the above-mentioned objectives are satisfactorily achieved, the characteristic details that make it possible and that distinguish it from what is already known are conveniently compiled in the final claims which accompany the present specification thereof.
  • the device is fitted with a feeding system for the receiving hopper which incorporates a safety locking system between said feeder and said receiving hopper in order to prevent flame blowback.
  • the biomass can be stored directly on the feeder worm shaft or in another previous hopper closed and arranged for this purpose.
  • the biomass receiving system is composed of said receiving hopper in which a central mixing unit is provided, which is in charge of supplying the burner installed at the other end of a horizontal connecting tube, inside the combustion chamber. Inside this horizontal tube which forms part of the said receiving system there is an auger which rotates by means of an electric motor and which is responsible for measuring out the biomass into the burner.
  • the fuel that fills the burner partially overflows onto a grate with boreholes which increases the combustion surface.
  • Combustion is completed through tubes which provide air onto the top of the flame (secondary air) with a variable flow fan.
  • first vertical tubes that are detachable and sliding, which slide on bushings, so that in this first passage of fumes, in which temperatures are very high, these first vertical tubes avoid being subjected to stresses that could destabilize the structure of the device.
  • These first vertical tubes are designed as a replacement part, extremely lowering the costs of repair work in the future. In order to change these first vertical tubes it is not necessary to remove the heat-exchanger unit, the side doors arranged for this purpose and other upper doors can be opened, through which the first vertical tubes can be removed and replaced with others.
  • the multi tubular heat-exchanger unit which contains the second set of vertical tubes, said tubes having a smaller diameter than the vertical tubes of the first previous passage in order to facilitate the cooling of the combustion gases.
  • the gases are forced to pass through several groups of second vertical tubes to ensure that the air from the air supply blower fan cools the gases efficiently, thus achieving high performance though heat exchange between the combustion gases and the air from the air supply blower fan.
  • combustion gases pass through these groups of second vertical tubes, they have to change the direction of displacement from bottom to top and vice versa. At this point they lower their speed, thereby achieving the decanting of most of the solid particles incorporated in the combustion gases.
  • This method of the passage of combustion gases enables the effective filtering of said solid particles from these same combustion gases.
  • the cleaning of the combustion gas passage decanters is very simple as they have easy to open side doors available for this purpose.
  • the vertical arrangement of the heat-exchanger unit also provides the advantage of facilitating the decanting of the ash generated in the combustion chamber, which settles easily in the lower portion of the heat-exchanger unit.
  • the large volume and surface of this decanter allows significantly lowering the speed of the combustion gases, and due to said decrease in speed, they settle on the bottom, thereby achieving an ash-free combustion-gas outlet.
  • Said receiving hopper (3) which is provided with a central mixing unit (5), feeds biomass to a horizontal tube (6) with another auger feeder with an inner worm shaft (2') which, driven by an electric motor (7) conveys the biomass to a burner (8) located at the other end of said horizontal tube (6) within a combustion chamber (9).
  • the burner (8) incorporates a lower grate (10) with boreholes onto which the biomass partially overflows, thus increasing the area of combustion.
  • a first decanter (11) of solid particles can be seen, as a kind of caisson, which is located before a gas-combustion outlet (12) (first gaseous fluid) towards a heat-exchanger unit (13) which is an independent element between it and said outlet (12) a first previous combustion-gas passage (I) formed by a set of several first vertical tubes (14) that are detachable and sliding, having a diameter greater than the second vertical tubes (16) of the heat-exchanger unit (13), with the particularity that said first vertical tubes (14) are assembled between the combustion chamber (9) and the heat-exchanger unit (13) located after the combustion chamber (9), on bushings (15).
  • the first vertical tubes (14) have upper and lower end sections which are fitted and assembled into recesses of the bushings.
  • the upper and lower end sections of the first vertical tubes (14) are fitted directly into recesses made in the structure of the upper caisson (17) and the combustion chamber (9).
  • the heat-exchanger unit (13) which is characteristically arranged as already noted behind the combustion chamber (9) constituting an independent element thereof, that can be detached and contains a second passage (II) determined by second vertical tubes (16); in this case having a smaller diameter than the first vertical tubes (14) from the first combustion-gas passage (I), and through which said combustion gases are also required to pass following a sinusoidal path, ascending and descending through these second vertical tubes (16) already connected in groups by means of the upper caissons (17) and other lower caissons (18) transmitting its heat to the air passing over the outside of one and the other vertical tubes (14, 16) which form part of the heat-exchanger unit (13) which is closed at the sides by the casing (19).
  • a second passage (II) determined by second vertical tubes (16) in this case having a smaller diameter than the first vertical tubes (14) from the first combustion-gas passage (I), and through which said combustion gases are also required to pass following a sinusoidal path, ascending and descending through these second vertical tubes (16) already connected in groups by
  • the device of the invention incorporates a blower fan (20) which is coupled to the heat-exchanger unit (13) in correspondence with the opposite end furthest from the combustion chamber (9), thus achieving optimal performance for heat exchange with the combustion gases; so that the blower fan (20) drives the hot air to a second outlet (21) for hot air located on top of the combustion chamber (9).
  • side cleaning doors (22) are provided in the casing (19) for this purpose, having also foreseen another cleaning door (22').
  • a last decanter caisson (23) is installed, which is connected to the suction tube (24) of an extractor (25) having variable flow to regulate the depression and outlet flow of the combustion gases, to which, in turn, a chimney-tube (26) is coupled for the outlet of said gases to the exterior.
  • the first and second vertical tubes (14), (16) are housed within a main chamber (1) of the heat-exchanger unit (13) which communicates with a casing chamber (27) located around the structure of the combustion chamber (9); wherein the stream of the second air gaseous fluid first flows through the main chamber (1) receiving heat from the first and second vertical tubes (14), (16) reaching a temperature of 300/400°C and then traverses the casing chamber (27) wherein the second air gaseous fluid increases its temperature (to 30°C and over) through heat transfer of the combustion chamber (9); the casing chamber (27) ending up in the second outlet (21) for hot air which reaches a temperature of up to 130/150°C.
  • the upper caissons (17) of the heat-exchanger unit (13) have the upper doors (29) facing the upper ends of the first and second vertical tubes (14), (16). Said upper doors (29) allow to carry out the cleaning and maintenance of the upper caissons (17), first and second vertical tubes (14), (16), and also allow the extraction of the first vertical tubes (14) or replacing them when necessary, as they are subjected to elevated temperatures (up to 600°C) due to their proximity to the combustion chamber (9).
  • the casing chamber (27) defines an annular space delimited by an inner wall (27a) and an outer wall (27b); wherein both walls are connected by ribbings (31) which are complemented by fins (32) which come out of the inner wall (27a).
  • the structure of the combustion chamber (9) has a front wall (30) which receives the impact of the stream of second gaseous fluid in its flow path to the casing chamber (27) which surrounds the structure of the combustion chamber (9); wherein said front wall (30) has a conical structure with a divergent surface from its center to its perimeter edge where it flows into the casing chamber (27). In this situation, the speed of the hot air stream inside the casing chamber (27) can reach up to 12 m/s.
  • the combustion gases which flow through the group of second vertical tubes (16) closest to the blower fan (20) can reach a temperature below 100°C even lower temperature than the air flowing through the area of that specific group of second vertical tubes (16); all of this depending mainly on the air flow supplied by the blower fan (20).
  • maximum heat exchange is achieved from the second vertical tubes (16) to the second flow of air. This sometimes implies that considerable condensation is generated inside this specific group of second vertical tubes (16), condensation which will be drained by means of a drainage duct installed on the bottom of the second decanter (23).
  • the pressure of the flow of hot air inside the device is always greater than the pressure of the combustion gases, so that although the vertical tubes (14), (16) or other internal parts of the device break, the pressure generated by the blower fan (20) combined with the depression generated by the fume extractor (25) prevent the combustion gases from passing into the flow of hot air used for example to dry grain in industrial warehouses, thus avoiding that a spark passes into the airflow possibly causing a fire.
  • the upper and lower end sections of the first vertical tubes (14) easily fit into the recesses of the first upper caisson (17) and the combustion chamber (9); wherein the heating of the first vertical tubes (14) increases their dimensions fitting tightly into the recesses of the first upper caisson (17) and combustion chamber (9), highlighting that said tightening allows the sliding of the first vertical tubes (14) during dilation when said first vertical tubes (14) are heated, which in one embodiment are made of stainless steel.
  • the top of the heat-exchanger unit (13) integrates a baluster so that the cleaning can be carried out safely.
