Abstract

Nei noti riscaldatori per acqua del genere in questione la sonda termometrica, prevista per sorvegliare il flusso del gas di scarico, è eseguita in qualità di termostato a contatto ed è fissata esternamente sulla parete della camera di combustione. Con questa disposizione la sonda termometrica viene altamente sollecitata termicamente ed oltre a ciò un'eventuale fuoriuscita del gas di scarico in corrispondenza del bordo inferiore della camera di combustione viene rilevata solo indirettamente attraverso un aumento della temperatura della parete della camera di combustione.Per effetto della disposizione in accordo con l'invenzione, della sonda termometrica (24) in un canale (28) del gas di scarico, che in prossimità del bordo inferiore (26) della camera di combustione (16) sbocca fuori da questa, la sonda termometrica (24) viene termicamente sollecitata in misura minore ed il ritorno di gas di scarico viene rilevato a causa di un contatto diretto tra la sonda termometrica (24) ed il gas di scarico.Campo d'impiego preferito sono i riscaldatori per acqua a circolazione riscaldati con gas per impianti di riscaldamento centralizzati.(Figura 1).
