Por lo tanto, la presente invención, se circunscribe dentro del ámbito de los dispositivos o medios empleados para lograr la ignición del coque de petróleo.Therefore, the present invention will be circumscribes within the scope of devices or media used to achieve ignition of petroleum coke.
En la actualidad los dispositivos existentes en el mercado diseñados para producir la ignición del coque de petróleo precisan de otro combustible adicional, como por ejemplo fuel-oil, gas, etc. Este combustible adicional es necesario emplearlo para conseguir la temperatura de 650ºC, que la temperatura a la que se produce la inflamación del coque y por lo tanto a esta temperatura el coque de petróleo ya puede quemar.Currently existing devices in the market designed to produce the ignition of coke from petroleum requires another additional fuel, such as fuel oil, gas, etc. This additional fuel is it is necessary to use it to achieve the temperature of 650ºC, which the temperature at which inflammation of coke occurs and so both at this temperature the petroleum coke can already burn.
El inconveniente de estos dispositivos es que precisan una instalación adicional de la propia necesaria para el coque, con objeto de conseguir la temperatura de ignición.The drawback of these devices is that they need an additional installation of the own necessary for the coke, in order to achieve the ignition temperature.
Por lo tanto, en la actualidad no existe en el mercado dispositivo alguno que permita conseguir la ignición del coque de petróleo empleando para ello un único combustible esto es el propio coque de petróleo.Therefore, at present it does not exist in the market any device that allows the ignition of the petroleum coke using a single fuel for this is The oil coke itself.
Por lo tanto, el objetivo de la presente invención es el de superar los anteriores inconvenientes, desarrollando para ello un dispositivo, en este caso una boquilla que permita conseguir la inflamación del coque de petróleo, para su ignición sin empleo de instalación adicional alguna para otro combustible.Therefore, the objective of this invention is to overcome the above drawbacks, developing for this a device, in this case a nozzle that allows to achieve the inflammation of the petroleum coke, to ignition without the use of any additional installation for another fuel.
La invención propuesta de boquilla para el autoencendido del coque de petróleo micronizado, consiste en una estructura tubular de interior hueco por donde se hace circular el fluido aire-coque de petróleo micronizado, estando todo el conjunto debidamente aislado mediante el empleo de materiales refractarios.The proposed invention of nozzle for self-ignition of micronized petroleum coke, consists of a hollow interior tubular structure through which the micronized petroleum air-coke fluid, being the whole set duly isolated by employing refractory materials
En el interior de la estructura tubular se dispone un tubo refractario directamente en contacto con el material refractario exterior que lo recubre y aísla. El material refractario exterior cuenta con una serie de rebajes donde se aloja una resistencia eléctrica encargada de hacer alcanzar la temperatura suficiente en el interior del conducto o tubo refractario interior con objeto de lograr la autoignición del coque de petróleo.Inside the tubular structure is It has a refractory tube directly in contact with the outer refractory material that covers and insulates it. The material External refractory has a series of recesses where it is housed an electrical resistor in charge of reaching the sufficient temperature inside the duct or tube interior refractory in order to achieve coke autoignition of oil
Con objeto de conseguir un mejor aprovechamiento del calor suministrado por la resistencia eléctrica, se forzará a que el coque micronizado pase lo más próximo posible a la superficie interior del conducto refractario, ya que es la parte que mayor temperatura va a alcanzar.In order to get a better use of the heat supplied by the electrical resistance, will be forced to that the micronized coke passes as close as possible to the inner surface of the refractory duct, since it is the part that higher temperature will reach.
Con el objetivo de forzar el paso del fluido de coque, lo más próximo posible a la superficie interior del tubo refractario interior, de forma concéntrica a este se dispone un vástago refractario de acero inoxidable, que presenta la parte superior de dicho vástago concéntrico de forma cónica, actuando como deflector del fluido aire-coque desviándolo hacia la superficie interior del tubo refractario interior.With the aim of forcing the passage of fluid from coke, as close as possible to the inner surface of the tube internal refractory, concentrically to this is arranged a stainless steel refractory stem, presenting the part upper of said concentric rod of conical shape, acting as air-coke fluid deflector by diverting it towards the inner surface of the inner refractory tube.
Por otro lado, con el objetivo de conseguir una salida uniforme del coque en ignición, el tubo refractario por donde circula el fluido finaliza en forma de cono, por lo que en su extremo final cuenta con un estrechamiento.On the other hand, in order to get a uniform ignition of the coke on ignition, the refractory tube by where the fluid circulates ends in the form of a cone, so in its final end has a narrowing.
Todo el tubo interior refractario está debidamente aislado con la finalidad de evitar pérdidas innecesarias hacia el exterior, así como evitar cualquier accidente en su manipulación. Con objeto de conseguir un adecuado aislamiento, el aislamiento consiste en ladrillo refractario-aislante que soporta una temperatura máxima de 1400ºC, este ladrillo está en contacto directo con el tubo refractario interior y es en donde se aloja la resistencia de calentamiento. Recubriendo a este ladrillo se dispone una placa de silicato de espesor de 25 mm, al que se le pegará fibra cerámica de espesor 25,4 mm. Todo este conjunto está recubierto por chapa de acero inoxidable.The entire inner refractory tube is duly isolated in order to avoid losses unnecessary outwards, as well as avoid any accidents in its manipulation. In order to get a proper insulation, insulation consists of brick refractory-insulator that withstands a temperature maximum of 1400ºC, this brick is in direct contact with the inner refractory tube and is where the resistance of heating. Covering this brick is a plate of 25mm thick silicate, to which ceramic fiber will be attached thickness 25.4 mm. This whole set is covered by sheet metal stainless steel.
La temperatura interior se logra, como ya se ha indicado por medio de una resistencia eléctrica alojada en una serie de rebajes con los que cuenta el ladrillo refractario-aislante, estando controlada la temperatura que se alcanza por medio de un regulador de temperatura, que se sirve de la señal proporcionada por un termopar tipo K encapsulado en una funda de cerámica refractaria.The indoor temperature is achieved, as already indicated by an electrical resistor housed in a series of recesses that the brick has refractory-insulator, the temperature that is reached by means of a regulator of temperature, which uses the signal provided by a thermocouple Type K encapsulated in a refractory ceramic sheath.
Alcanzada la temperatura interior necesaria para la ignición del coque de petróleo micronizado y se haya inflamado durante un tiempo determinado, la resistencia se desconecta, ya que el coque puede arder sin necesidad de una ayuda externa.Reached the internal temperature necessary for the ignition of micronized petroleum coke and it has become inflamed for a certain time, the resistance is disconnected, since Coke can burn without the need for external help.
En caso de re-encendido o si no se alcanza la temperatura de ignición, el regulador de temperatura hará que se conecte de nuevo el suministro de calor a través de la resistencia.In case of re-ignition or if not the ignition temperature is reached, the temperature regulator will cause the heat supply to be reconnected through the resistance.
