Abstract
La presente invención se refiere a la combustión de un combustible que contiene azufre, un método para reducir el contenido de dióxido de azufre (SO2) de los gases de reacción de combustión, consistiendo el método de los pasos de: introducir un combustible que contiene azufre dentro de la primera zona, en una cámara de combustión cerrada; introducir una primera porción del aire hacia la primera zona por lo menos estrechamente adyacente al combustible para por lo menos tomar parcialmente el combustible y producir los gases de reacción de combustión que contienen dióxido de azufre; introducir una segunda porción de aire hacia la cámara de combustión en una segunda zona separada de manera relativamente distante de la primera zona; hacer fluir el contenido de la primera zona en aguas abajo a traves de la segundo zona; controlar el sitio en el cual se introduce la segunda porción de aire y la velocidad del mismo, para amortiguar la temperatura máxima de la llama y proporcionar un frente de llama relativamente uniforme en la segunda zona; proporcionar partículas finamente divididas de un material que forma cal al exponerse al calor en la sgunda zona; introducir las partículas dentro de la segunda zona junto con y bajo el empuje de la segunda porción de aire, sin premezclar las partículas y la segunda porción de aire antes de que entren en la segunda zona; y emplear la segunda porción de aire para distribuir las partículas a traves de los gases que fluyen en aguas abajo a traves de la segunda zona.The present invention relates to the combustion of a sulfur-containing fuel, a method of reducing the content of sulfur dioxide (SO2) in the combustion reaction gases, the method consisting of the steps of: introducing a sulfur-containing fuel within the first zone, in a closed combustion chamber; introducing a first portion of the air into the first zone at least closely adjacent to the fuel to at least partially take up the fuel and produce the sulfur dioxide-containing combustion reaction gases; introducing a second portion of air into the combustion chamber in a second zone relatively distant from the first zone; flow the contents of the first downstream zone through the second zone; controlling the site into which the second portion of air is introduced and the speed thereof, to dampen the maximum flame temperature and provide a relatively uniform flame front in the second zone; providing finely divided particles of a lime-forming material upon exposure to heat in the second zone; introducing the particles into the second zone together with and under the thrust of the second air portion, without premixing the particles and the second air portion before they enter the second zone; and employing the second portion of air to distribute the particles through the gases that flow downstream through the second zone.
