1.0 INTRODUCTION

     The condenser is a box type construction with divided water box design double flow; two pass which facilitates the operation of one half of the condenser while other half is under maintenance. The steam space is of rectangular cross-section with integral air-cooling section from where air and noncondensable gases are drawn out with the help of air evacuation equipment.

2.0 CONSTRUCTION

    2.1 The surface condenser is mounted on spring supports. The condenser is welded with the exhaust hood of the low-pressure turbine. The tube plates are welded with the water chambers. Condensers are provided with domed shape water box. The condenser tubes are supported within the condenser shell by tube support plates, which are so spaced that the vibrations of the tubes are prevented under normal operating conditions. The condenser is installed in such a way that all condenser tubes are drained automatically into the condenser water boxes.

    2.2 NECK

    Condition has been provided with an extension suitably to connect it to the turbine exhaust opening. Adequate internal clearance is provided. The rigid construction results in a sound-condenser combination for trouble free operation.
