Low temperature catalytic delisting process

Introduction to Yuneng Low Temperature Catalytic Denitration Process (YNSCR):

The system relies on the principle of selective catalytic reduction (SCR), integrates the advantages of various low-temperature flue gas treatment processes, and integrates the professional technology independently developed by our company. It owns independent core technology property rights of flue gas denitration treatment.

YNSCR technical advantages:

1) YNSCR system integrates the advantages of denitration process and the professional technology independently developed by our company. Significant technical advantages, advanced and mature technology, economic and reasonable cost, small number of operators, low operation cost, simple and convenient operation and maintenance, safe and reliable system, efficient and energy-saving.

2) YNSCR system adopts advanced, mature and reliable technology, with economic cost, reasonable system design, simple operation and convenient maintenance. The system is equipped with enough hinged manhole doors, which are easy to open/close, and maintenance platforms are set near all manhole doors; It is convenient for operation and maintenance; Efficient availability; Low operation cost; Simple observation, monitoring and maintenance; The number of operators is small; Ensure the safety of personnel and equipment; Save energy, water and raw materials;

3) YNSCR system adopts CFD flow field simulation analysis design to reduce flue gas resistance; In the closed state, the leakage rate of the sealing device is zero, and the flue gas is not allowed to leak into the atmosphere.

4) The commissioning, start/stop and operation of YNSCR system will not affect the normal work of the host, and its progress is subject to the progress requirements of the host system. The commissioning plan of the denitration device matches the commissioning plan of the host. It meets the requirements of automatic operation under various working conditions, and the normal operation monitoring and accident handling of the system are fully automated.

5) YNSCR system has the response ability to adapt to the temperature fluctuation of kiln operation, and the function of over temperature exit, which can ensure long-term safe operation.

6) The reducing agent injection design of YNSCR system is optimized and reasonable, with the characteristics of wear resistance, high temperature resistance and easy replacement. It can reliably control the ammonia nitrogen ratio (NSR), calibrate the nozzle flow, and optimize the design of control strategy based on experimental experience to quickly respond to furnace operating parameters and NOx emission fluctuations.

7) The YNSCR system can meet the requirements of the system working conditions with variable load and combustion parameters of the kiln unit. The operation of denitration device and all auxiliary equipment has no or minor impact on furnace load and equipment. The denitration device can operate at any point between the minimum and maximum flue gas emission concentration, with good regulation performance.

8) In order to ensure the project quality, the denitration effect required by the project can always be achieved during the service life. The equipment and components provided by YNSCR system are all reliable and high-quality products that have been verified by operation.
