Abstract

La presente invención se refiere a una caldera (10), en particular una caldera de condensación (10), que comprende al menos una zona de combustión (13) y un quemador (11) dispuesto en correspondencia con dicha zona de combustión (13) a lo largo de un eje longitudinal (y), y al menos un primer intercambiador de calor (1) adaptado para rodear dicho quemador (11) con su parte interna (7) orientada hacia dicho quemador (11) y expuesta directamente a la llama de dicho quemador (11), cuando está en uso. Dicho intercambiador de calor (1) proporciona un conducto de acero, preferiblemente de acero inoxidable, con un perfil en espiral y que comprende una pluralidad de bobinas (2) con un eje de simetría común (y), coincidiendo el eje de simetría (y) de dicho primer intercambiador de calor (1) con dicho eje longitudinal (y) de la caldera (10). Dicha caldera (10) se caracteriza porque la parte interna (7) orientada hacia dicho eje de simetría (y) de cada bobina (2) de dicho primer intercambiador de calor (1) tiene una depresión continua. (9) a lo largo de al menos una porción de dicho perfil en espiral. (Traducción automática con Google Translate, sin valor legal)
