It is analyzed that the use of condensate equipment is effective to decrease the excessive dissolved oxygen in condensate in the light of the introduction of newly built 2×600 MW direct air-cooling unit combined exhaust equipment operation condition in Shanxi Wuxiang Hexin Generation Co.

It is proved that the use of joint exhaust installation is effective to deoxidize based on the discussion on the sample of Shanxi Wuxiang Power Plant 2×600 MW unit.

By combining k-ε models with the wall function calculation method and using the SIMPLE method for programming,the flow field in exhaust facility,which has a low pressure heater and pressure reducer and desuperheater in it,has been treated with three-dimensional numerical simulation and the velocity distribution of the flow field in exhaust facility is herewith obtained.

The article presents the structural features,requirements of installation and test,means and operation for exhaust facility of 600MW direct air-cooled turbine to make readers fully understanding about the (exhaust) facility.

By combining SIMPLE algorithm and model,the three-dimensional numerical simulation has been made for the flow field in 300MW exhaust facility,which has a low pressure heater in it,for direct air cooling unit and the velocity distribution of the flow field in entire exhaust facility has been obtained.

Causes of level imbalance among exhaust equipments in one 600 MW direct air-cooling unit during its speeding up process were found in this essay through analysis of its structure and operation mode.

The essay describes the DFSTW s exhaust equipment of direct air cooling turbine in which the round pipe has being used worldwide to replace the traditional square exhaust pipe.

Two design schemes have been put forward in order to make the exhaust equipment fixed with a condensate box into a combined equipment with functions of built-in deaeration and heating in the air-cooling power unit.
