Descripción

Caldera pirotubular

La caldera pirotubular es un tipo de caldera en la que el gas caliente pasa del fuego a través de uno o más tubos que atraviesan un recipiente de agua sellado. El calor del gas se transfiere a través de la pared del tubo mediante conducción térmica, calentando el agua y generando vapor. Las calderas pirotubulares son el tercero de los cuatro tipos históricos de calderas: calderas de tanque de baja presión o calderas de "almiar", calderas de humos con uno o dos grandes conductos de humos, calderas pirotubulares y calderas de alta presión con muchos tubos pequeños.

Caldera acuotubular

La caldera acuotubular es un tipo de caldera en la que el agua circula por tubos calentados externamente por el fuego. El combustible se quema en el horno para producir gas caliente, que calienta el agua en el tubo de generación de vapor. En calderas más pequeñas, los tubos adicionales de generación de energía están separados en el horno, mientras que las calderas de servicios públicos más grandes dependen de los tubos de inyección de agua que conforman la pared del horno para generar vapor. Caldera acuotubular de alta presión: El agua caliente asciende al depósito de vapor. Aquí, el vapor saturado se extrae de la parte superior del tambor.

Uso de tubos de calderas

- Calderas de vapor

- Generación de energía

- Plantas de combustibles fósiles

- Centrales eléctricas

- Plantas de procesamiento industrial

- Instalaciones de cogeneración
