Hi Sumon,
My company is the world leader in soot blower technology. I am headquartered in the the USA but we have a sister company in India that can provide the information you require. I have forwarded this inquiry to Sumit Gupta at Clyde Bergemann India. His email is sgupta@clydebergemann.in

Please let me know if we can be of further assistance.
