Dry gas cleaning system for cupola : From concept to commissioning - A case study

Chaudhuri, S P and Mishra, K K and Ramachandrarao, P (2000) Dry gas cleaning system for cupola : From concept to commissioning - A case study. In: UNSPECIFIED.



Most of the foundries in India are coke-based . They are usually besieged with pollution control problems. Normal stack emission from cupolas ranges from 1000 to 2500 mg/Nm3 of Suspended Particulate Materials(SPM) which is much higher than the acceptable limit of 150 mg/Nm3 fixed by Central Pollution Control Board (CPCB). National Metallurgical Laboratory (NML), which has considerable research experience in the development of dry gas cleaning system for cupolas was, in recent past, entrusted by Central Growth Works (Kulti), to study, design and install three number gas cleaning plants for six cupolas in their works. The project was successfully completed by NML and the SPM level attained was much below the CPCB Norm. In this case study, the authors present the various aspects of the project, namely the design parameters, installation/trial run/commissioning activities etc towards achieving the desired SPM level.
