Abstract

PURPOSE: To change sets of fans to be operated freely and stably by a method wherein air volume regulations for a plurality of fans are effected in accordance with a pressure control signal and the pressure control signal is converted into a delayed signal having a predetermined time gradient upon changing the sets of fans to be operated.
CONSTITUTION: When only the first fan 1 is being operated, a damper 2 is fully opened, a pressure control signal generated in a pressure regulator 13 in accordance with an output of a pressure transmitter 12 is given to a vane operator 5 through an electric-air transducer 20 and an air volume regulation is being effected by a regulation of an opening of a vane 3. When a volume of combustion air is exceeding a predetermined value under this condition, the second fan 6 is started by an operation of a control device 15 operated by a signal generated from a monitor switch 14 and a damper 7 is fully opened by a operator 9. Then, a contact 18 for a signal convertor 16 is closed subsequently, a pressure control signal of the pressure regulator 13 is given to an operator 10 through a delay circuit 17 and an electric-air transducer 21, thereby, a vane 8 is opened gradually.
