Valmet to supply new recovery boiler to ITC in India
Finland-headed forest industry and energy technology provider Valmet Oyj has announced that it will deliver a new recovery boiler and ash leaching plant to ITC Paperboards and Specialty Papers Division's Bhadrachalam pulp mill in India. With start-up scheduled for late 20121, the new boiler will replace three existing boilers.
ITC Paperboards and Specialty Papers Division is a leading paper and paperboard business with solutions to meet a diverse cross-section of packaging and communication needs. With an emphasis on harnessing state-of-the-art technology, the company has emerged as the largest manufacturer of packaging and graphics board in South Asia.
ITC’s Paper Board And Specialty Paper’s Division has eleven machines at three locations with a combined production capacity of 800 000 tonnes per annum (TPA).
The new recovery boiler investment is an essential part of increasing the mill’s pulp production. Our main drivers for choosing a modern state-of-the-art recovery boiler were reliability, energy efficiency and environmental performance. With their offering Valmet was able to meet our goals, said Sanjay Singh, Divisional Chief Executive of ITC.
Scope of supply
The Valmet RECOX+ recovery boiler will have a capacity of 2 700 tDS/day. Valmet says that the boiler includes several high-power features such as high steam parameters, flue gas heat recovery, combustion air preheating, feed water preheating and vent gas heat recovery.
This, the company says, enables 20 percent higher steam production compared to conventional recovery boilers. The medium size and high steam parameters set specific requirements for material design.
The delivery also includes electrostatic precipitators (ESPs) which remove dust particles from recovery boiler flue gases. Potassium and chloride levels in the ESP ash are controlled with two-stage ash leaching system, “AshLeach Duo” which Valmet says is a “well-proven, uniquely simple and effective” system.
Although the value of the new recovery boiler order has not been disclosed, Valmet indicates that the value of an order of this scope is typically around EUR 50-60 million.
This recovery boiler represents a new era in Indian recovery boilers. It is significantly larger than the boilers previously delivered to India and has high power features which enable the mill to increase its energy production. With this project, we are able to utilize our technology leadership and strong local presence in India. We are happy to continue our very good cooperation with ITC in upgrading their production fleet, said Jussi Mäntyniemi, Vice President, Recovery Business Unit, Pulp and Energy, Valmet.
