| titleOfInvention | Corrosion protection technology for shutdown and standby of thermal system of gas-steam combined cycle unit |
| abstract | The invention discloses a corrosion protection process for the thermal system of a gas-steam combined cycle unit when it is shut down. The invention includes a gas-flue gas system dry air protection process and a waste heat unit water vapor system dry air combined protection process; the gas-flue gas system dry air protection process adopts a low-humidity dry air ventilation drying scheme, and the waste heat unit water vapor system dry air combined protection process A combined protection scheme of chemical corrosion inhibition and dry air drying is adopted; the dry air combined protection process of the water vapor system of the waste heat unit is divided into four stages: waste heat drying, corrosion inhibitor protection, ventilation and drying, and humidity maintenance. The invention fully adapts to the characteristics of the gas-steam combined cycle unit system structure, operation mode, frequent standby and uncertain outage time, etc., and can realize the anti-corrosion protection of the whole system and the whole period when the thermal system is out of service, and can control the outage to the greatest extent. Equipment corrosion during transportation, with a wide range of applications, flexible operation, economic and environmental protection and other significant advantages. |
