Abstract
Un método y aparato para la calcinación del yeso bajo presión para obtener hemihidrato alfa a través de un proceso continuo. Se provee un reactor presurizado que incluye una fuente de calor, preferiblemente un intercambiador de calor, y un aparato para inyectar el gas calentado y el aire para crear una lecho fluidizado. El yeso extraído de minas o el yeso sintético se inyecta dentro del reactor en una base continua para calcinación en el reactor. De ésta manera el hemihidrato alfa calcinado es producido teniendo una proporción de A/E en un rango general entre 0.45-0.55. En la modalidad preferida, se provee un segundo inter intercambiador de calor, puesto que es un reactor con un aparato interno de taladro calentado. Se utiliza un sistema continuo de medición para introducir el yeso al reactor en un proceso continuo y para mantener la presión en el reactor. El presente método también caracteriza un desvío del aire calentado de una fuente de calor para el inter cambiador de calor para proveer también gas calentado al lecho fluidizado del reactor. 1.- Un método para la calcinación del yeso, que comprende: inyección del yeso dentro del reactor presurizado; inyección de gases y aire de combustión dentro del reactor presurizado para crear un lecho fluidizado de yeso en el reactor; y calentar el lecho fluidizado del yeso en el reactor presurizado para calcinar suficientemente el yeso para formar un hemihidrato calcinado. 2.- El método de la reivindicación 1, en donde el hemihidrato calcinado secado tiene una proporción de agua al estuco en un rango aproximado de 0.45 - 0.55. 3.- El método de la reivindicación 1 que comprende además: la continua alimentación del yeso a través de un aparato continúo de medición dentro de un reactor presurizado.
