The Fourth Stage Project of Zouxian Power Plant is to re-expand two super-supercritical electric generator sets(2×1000 MW);which deploys a double-barrelled chimney with 240 m height and each top export of the exhaust cylinder has a inside diameter of 8 m.

Through the experiment and theoretical analysis, this article inquires into the main reasons of corrosion cracking of chimney of the stove heated by water sleeve and proposes the basis for developing corrosion-resistant materials of chimney of the stove heated by water sleeve.

Comparison of different methods of ventilation and smoke exhaust in underground parkings;

Analysis on ventilation and smoke exhaust for civil air defense underground garages;

Discusses on ventilation and smoke exhaust system design for basement of highrise civil buildings;

In the article we not only analysed the theory of flue gas condensation, but also studied the theory that the various parts of flue gas was absorbed and purified in the course of the flue-gas condensation.

Aimed at the fact that the wall temperature of heat exchanger is lower than the dew point of flue gas, the thermal energy utilization system for flue gas of positive draft gas boiler is proposed.
