Abstract:

Nowadays, many domestic thermal power plants use low temperature economizers to reduce the exhaust gas temperature and improve the economy of units.Taking the operation status of a 1000MW secondary reheat unit low temperature economizer as an example, it puts forward the existing problems and corresponding improvement measures of low temperature economizer, which provides reference for the design and operation of low temperature economizer systems of units of the same type.

Key words:

secondary reheat, low temperature economizer, flue gas waste heat, improvement measures
