Abstract

Una caldera pirotubular o aquatubular que permite mejorar la combustión, disminuir las emisiones de material particulado y aumentar el rendimiento de la caldera logrando una disminución significativa del consumo de combustible en torno al 50% en comparación con una caldera con sistema tradicional; la caldera comprende 5 etapas, las que están dispuestas de manera que, en una primera etapa, la caldera presenta una cámara de combustión que se encuentra recubierta de material refractario que evita el enfriamiento de los gases de combustión, generando temperaturas de 700° o superior; en una segunda etapa presenta un túnel mezclador que recibe los gases no totalmente quemados desde la primera etapa y se adiciona aire, produciéndose en este túnel mezclador una mezcla de los gases no totalmente quemados, y produciendo una segunda combustión, la cual sale con gran velocidad, como si fuera un quemador, hacia una cámara de expansión; en una tercera etapa, la caldera presenta la cámara de expansión en la que los gases que vienen desde el túnel mezclador se expanden y pierden velocidad de flujo, debido al aumento de la sección en la cámara de expansión, logrando así un mayor tiempo de residencia de los gases y un aumento del intercambio térmico; además, dentro de la cámara de expansión simultáneamente se decanta el material particulado y se produce una limpieza de los gases de combustión; en una cuarta y quinta etapas, la caldera incluye un conjunto de elementos intercambiadores de calor en donde se vuelve a transferir el calor al liquido térmico.A fire-tube or water-tube boiler that improves combustion, reduces particulate matter emissions and increases boiler performance, achieving a significant reduction in fuel consumption of around 50% compared to a boiler with a traditional system; the boiler comprises 5 stages, which are arranged so that, in a first stage, the boiler has a combustion chamber that is covered with refractory material that prevents the combustion gases from cooling, generating temperatures of 700° or higher ; in a second stage it presents a mixing tunnel that receives the gases not completely burned from the first stage and air is added, producing in this mixing tunnel a mixture of the gases not completely burned, and producing a second combustion, which comes out with great speed , as if it were a burner, towards an expansion chamber; in a third stage, the boiler presents the expansion chamber in which the gases that come from the mixing tunnel expand and lose flow speed, due to the increase in the section in the expansion chamber, thus achieving a longer residence time of gases and an increase in heat exchange; In addition, inside the expansion chamber, the particulate material is simultaneously decanted and the combustion gases are cleaned; In a fourth and fifth stages, the boiler includes a set of heat exchanger elements where the heat is transferred back to the thermal liquid.
