Claims

[Scope of utility model registration request]

CDQ main body, high temperature gas flow path equipped with a primary dust collector,
In a CDQ facility configured as a closed system consisting of a boiler equipped with a deaerator for water supply and a circulating gas flow path for cold gas supply equipped with a secondary dust collector, the cooling air stream is used as a primary duct collector. Using a cyclone equipped with a circulating closed circuit, a feed water preheater is provided in the closed circuit, low temperature water from a water supply source is passed through the feed water preheater, and the low temperature water is obtained by heat exchange with the circulating air flow in the closed circuit. A CDQ characterized by being configured to supply heated water to a boiler feed water deaerator.
Boiler feed water preheating device in equipment.
