Analysis and Countermeasures of High Deposit Rates in 600 MW Supercritical Once-through Boiler
The chemistry check-up is made in the first maintenance of the supercritical once-through boiler 600 MW units in Henan Province. It is shown that the deposit rates are high on the water-cooled wall, coal economizer, and the turbine blade. The formation of salt deposition is complicated in the turbine blade. According to the operational status, the reasons are analyzed and the suggestions provided.
