Abstract
A single thermoelectric device designed to operate both as an igniter and flame detector for gas burners is described. Ignition is performed via heating, by Joule effect, of a conductor which can have, preferably, catalytic activity on the combustion while the flame is detected by means of a “hot” thermal state via the seeback effect. Both functions are obtained via control of a circuit for delivery of the power and detection and amplification of the electrical signal correlated to the flame.
Claims11
Electrothermal device for ignition and flame detection in a gas burner which comprises a thermoelement, including a pair of joined metal elements, each one supported on a respective rheophore, said metal elements being able to generate thermoelectric voltages and currents when the junction is placed in an environment with temperature different from that of the rheophores, said thermoelement igniting the gas burner by the Joule effect when the rheohpores are suitably connected to an electrical energy source and impedance circuitry.
