system for ventilating boiler

摘要

PURPOSE: A system for ventilating a boiler is provided to reduce fan noise by setting a section to avoid vibration and rotating the motors of a press-fitting ventilator and an inducing ventilator if necessary. CONSTITUTION: A system(100) for ventilating a boiler comprises at least one electrical dust collector(106), a chimney(108), at least one air switch(110), at least one fuel gas switch(112), a first control unit(114), a main control unit(116), a first speed-variable power converter(118), and at least one second speed-variable power converter(120). The first control unit calculates the number of rotation required for the inducing ventilator or opening ratios required for the air switch and the fuel gas switch. The second speed-variable power converter receives the opening ratio required for the fuel gas switch.
