Wanhua Chemical (Ningbo) Thermal Power Co., Ltd.
This project is the main project of the Phase II expansion project of Wanhua Chemical (Ningbo) Thermal Power Co., Ltd., Ningbo Daxie development zone. It is 1 x 410 t/h CFB boiler flue gas denitrification unit, which is contracted by the company for EPC. This project adopts the selective non catalytic reduction denitration (SNCR) technology, the design of the denitration efficiency is no less than 55%, use aqueous ammonia as the reducing agent , outlet NOx is not more than 100 mg/Nm3, ammonia slip is less than 8 mg/Nm3, and denitration unit lifetime is not less than 20 years.
Ningbo Jiufeng Power Co., Ltd.
The scale of this project is 4130 t/h sub-high temperature pressure circulating fluidized bed (CFB) boilers. Ningbo Jiufeng Power Co., Ltd. is a regional centralized heating and thermal power plant. The thermal load is relatively stable, and the operation mode of the thermal power plant is determined by thermoelectric and cogeneration. The #1-#3 boilers flue gas denitrification units adopt the SNCR + SCR combined denitration process. Under the conditions of design coal, check coal and treating the maximum working condition of the boiler, the NOx concentration at the denitrification inlet is 300 mg/Nm3. Denitrification efficiency guaranteed value is 75%. #4 boiler uses SNCR technology alone, and the denitrification efficiency guarantee value is 60%.
Inner Mongolia Datang International Keshiketeng Coal to Gas Co., Ltd.
The project is a 4470t/h coal-fired boiler denitration retrofit project for the Phase I of the power zone of the Datang International Keshiketeng Coal to Gas Project in Inner Mongolia. The project adopts SCR, the NOX content of the denitrification reactor inlet is 400mg/Nm3, the NOx content of the outlet is 80mg/Nm3, and the designed denitration efficiency is not less than 80%.
