FIELD: technological processes; heating.
SUBSTANCE: required consumed electric current should be insignificant for provision of possibility to use inbuilt source of voltage. It is achieved by the following procedure: after actuation of control device supplied from voltage source thermoelectric valve of safe firing system opens and exhaust gas is fired. Mentioned thermoelectric valve of safe firing system is maintained in open condition with the help of electromagnet of safe firing system with the help of holding current from source of voltage until thermocouple provides necessary holding current after firing that took place, or preset time delay is exceeded.
EFFECT: possibility of firing in remote control mode; possibility to use inbuilt source of voltage and simplification of device design.
