Siemens to modernize off-gas cleaning system in Tata Steel’s converter steel plant in India – Jul 14, 2014– Linz, Austria (Techreleased) – Siemens Metals Technologies has received an order from Tata Steel, an Indian steel producer, to modernize the secondary emission system in LD2 shop in Jamshedpur. The aim is to reduce emissions – both in the plant itself and in the exhaust air – to reduce to a level as per the regulatory norms. In future, dust levels in the factory will be less than 4 mg/Nm3, and will not exceed 30 mg/Nm3 at the stack. The project is part of Tata Steel’s campaign to reduce its local environmental impact and is scheduled to be completed by the end of 2016.

Tata Steel runs an integrated steel plant in Jamshedpur, Jharkhand State, India, which has an annual production capacity of 9.7 million metric tons of crude steel. There are three LD (BOF) converters with tapping weights between 165 and 180 metric tons.

Siemens will comprehensively modernize the existing secondary emission system in the steel plant. Siemens will also design, engineer, manufacture and supply the requisite equipment. This includes induced draught fans, electrostatic precipitators, and systems to handle and transport the filtered dust, as well as the associated electric motors, drives and the automation hardware and software. Siemens will also modernize two existing electrostatic precipitators and modify the duct system and the converter housings. In advance of the order, Siemens carried out an analysis of the emissions in the converter steel plant, and made recommendations for improvement which will be implemented under the order. Siemens will also be responsible for supervising the installation and commissioning work.
