| Abstract: | In De-NOx urea pyrolysis sestem,the required high-temperature pyrolysis air heat is generally provided by electric heater.The flue gas heat exchanger arranged in the boiler flue can effectively provide the heat required for high-temperature pyrolysis air heating,reduce the operation power of the electric heater,and save high-quality electric energy.By analyzing the actual operation data of a 350 MW unit,the operation characteristics of urea pyrolysis system with built-in flue gas heat exchanger of boiler are summarized,and the optimal design scheme of flue gas heat exchanger is proposed to ensure the operation economy and reliability of urea pyrolysis ammonia production system. |
