Abstract:

In combination with the rating data for various kinds of CDQ boilers and constraint factor existed in selection process of CDQ boiler, the factors such as productivity of CDQ, project investment and enterprise present situation were compared and analyzed, which has provided a suggestion for selection of boiler type for CDQ project. At the same time, against high temperature and high pressure natural circulation CDQ thermal system and medium temperature and medium pressure combined circulation CDQ thermal system, the difference of energy-saving, boiler efficiency, steel consumption, system electric power consumption, power generation capacity as well as the difference between boiler start-up and running were compared and analyzed, every advantage and disadvantage of thermal systems of two parameters were understood furthermore.
