Abstract

Secondo l'invenzione si realizza un'apparecchiatura di comando e controllo per bruciatori a gas che si caratterizza per il fatto che al raggiungimento del valore di riferimento della grandezza fisica da controllare, permanendo la fiamma nel bruciatore dopo la disalimentazione dell'elettrovalvola di sicurezza del gas, permane l'alimentazione elettrica del motore (M) dell'elettroventilatore che fornisce l'aria di combustione, detta alimentazione essendo assicurata dalla chiusura dei contatti (B1, B2), posti a monte del motore (M) dell'elettroventilatore, di un primo relè (B) appartenente al circuito di potenza ed eccitato dalla chiusura di un contatto (1E) normalmente chiuso, detto contatto normalmente chiuso appartenendo ad un secondo relè (E) diseccitato inserito nella parte logica dell'apparecchiatura, detto secondo relè (E) essendo posto in serie ad una prima resistenza (BLG) avvolta su di un elemento bimetallico ed in parallelo ad un contatto chiuso (2RF) appartenente al circuito logico (A RF) di rilevazione della fiamma, l'alimentazione del motore (M) dell'elettroventilatore cessando allo spegnimento della fiamma per la commutazione del contatto (2RF) appartenente al circuito logico (A RF) di rilevazione fiamma.
