Title (EN) COAL FURNACE
(FR) POELE A CHARBON
Abstract: front page image
(EN)Coal furnaces for space heating are usually adapted for functioning according to the principle of thorough combustion. The optimum combustion is achieved by adequate regulation of the proportion between primary and secondary air. This is often difficult and necessitates a supervision of the combustion. By arranging furnaces with a perforated air pipe (7) in the middle of the combustion chamber (4) an automatic regulation of the proportion between the primary and secondary air is achieved. The air pipe (7) is detachably mounted in a hole (6) at the bottom of the combustion chamber (4) through which hole (6, 4) an air channel (9) is connected to an adjustable air valve (3) at the front of the furnace.
(FR)Des poeles a charbon pour le chauffage d"espaces sont generalement adaptes pour fonctionner selon le principe de la combustion complete. La combustion optimale est obtenue par un reglage adequat de la proportion entre l"air primaire et l"air secondaire, ce qui s"avere souvent difficile et requiert un controle de la combustion. En disposant dans le poele une conduite d"air perforee (7) au milieu de la chambre de combustion (4) on obtient un reglage automatique de la proportion entre l"air primaire et l"air secondaire. La conduite d"air (7) est montee de maniere demontable dans un trou (6) sur le fond de la chambre de combustion (4) et au travers de ce trou (6, 4) un canal d"air (9) est connecte a une soupape d"air (3) reglable situee sur la partie frontale du poele.
