District heating system using power station waste heat - uses condenser cooling water fed through two groups of buildings in series

摘要

The condenser cooling water of an electricity power station flows through the condensers of two generating units in series. It is then pumped to a storage reservoir which is equipped with emergency or auxiliary burners. From the reservoir, the water is taken by a single flow pipe to the radiators of buildings from which it flows to the radiators of a second group of buildings before being discharged to waste. The power station condensers work at normal temperatures for maximum efficiency. The radiators in the first group of buildings have larger than normal surfaces to give adequate heating at low flow temperatures. The radiators of the second group of buildings are sized to work at lower temperatures than those of the first.
