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.According to the invention, a command and control apparatus for gas burners is created which is characterized in that upon reaching the reference value of the physical quantity to be controlled, the flame remains in the burner after the power supply safety valve of the gas, the power supply to the motor (M) of the electric fan that supplies the combustion air remains, said power supply being ensured by the closure of the contacts (B1, B2), located upstream of the motor (M) of the electric fan, of a first relay (B) belonging to the power circuit and excited by the closing of a normally closed contact (1E), said normally closed contact belonging to a second de-energized relay (E) inserted in the logic part of the equipment, called second relay (E ) being placed in series with a first resistance (BLG) wound on a bimetallic element and in parallel with a closed contact (2RF) belonging to the circuit flame detection logic (A RF), the power supply to the motor (M) of the electric fan, ceasing to switch off the flame for switching the contact (2RF) belonging to the flame detection logic circuit (A RF).
