The definition of power changes of condensational power stations at switching a GAS expansion unit into a heat power scheme

摘要

The question of switching a gas expansion unit into its heat power scheme at condensational power stations is considered. The formulas obtained allow to determine the changes of power at power stations while switching a gas expansion unit at constant use of steam both with and without intervening steam overheat. In the first case two variants of switching a gas expansion unit into the heat power scheme of conditional power stations are studied; while picking out steam for gas heating before GEU before intervening steam overheat and after it.
