Water-controlling electronic valve driving apparatus and method for condensate neutralization of heat recovery boiler

摘要

PURPOSE: A water electronic valve driving device is provided to improve durability and reduce noise. CONSTITUTION: A controlling portion(60) controls general operation of a boiler. A gas electronic valve(34) determines whether to supply gas to a burner. A circulation pump(37) supplies heating water to a heat exchanger(44). A siphon(39) mixes acid condensate water discharged from the heat exchanger with water to neutralize. A water electronic valve(26) supplies water selectively to the siphon(39).
