Wonder Cement of Udaipur, Rajasthan, has planned to set up an 18-MW waste heat recovery system to meet the power requirements of its upcoming second line expansion of its Nimbahera cement plant in Rajasthan.
S.M. Joshi – President (Plant), Wonder Cement, told Projectmonitor, “Our current 40-MW captive power plant is enough for the present Line-1. For Line-2, we will be putting up another 40 MW power plant but not with the construction of this line. With this second line, we are putting up a waste heat recovery system of 18 MW capacity. Therefore, there will be a shortfall of 22 MW but actually 18 MW only because 4 MW is internal consumption; our plant requirement is 36 MW. For the balance requirement, we have a grid connection.”
The orders for the 18-MW waste heat system have already been placed with Thermax and ThyssenKrupp. The orders for the second 40-MW power plant have not been placed as the project is still at a nascent stage. But it will be a PET coke-based plant which is more economical, Joshi added.
Another company official stated that the expenditure for the 18-MW waste heat recovery system would be roughly around Rs. 10 crore per megawatt totalling around Rs. 180 crore for the entire plant. The costs could have been lower if Chinese machinery was used but the company has selected reputed suppliers to ensure better quality.
The need for additional power has arisen because the company is currently undertaking capacity expansion costing around Rs. 1,200 crore at its Nimbahera plant in Rajasthan wherein a second line is being installed. The second line is under execution with completion expected by the end of 2015. The project financial closure is currently under progress.
Wonder Cement is part of the RK Marble Group. According to the company’s website, its Nimbahera cement plant has a capacity to produce 3.25 million tpa. The company has plans to expand its current capacity to 10 million tpa in due course by setting up a second and third production line for which land and layout are ready.
