L&T has a long-term technical licence agreement with Chiyoda Corporation, Japan, for its ‘Chiyoda Thoroughbred 121TM (CT-121TM)’ Flue Gas Desulphurisation (FGD) technology. The agreement grants L&T exclusive rights to undertake EPC of CT-121TM FGD systems. The CT-121TM FGD process is a unique technology, characterised by a gas liquid contacting device called Jet Bubbling Reactor in which sulphur dioxide is absorbed from flue gas generated by coal-fired, oil-fired and other types of boilers and removed as gypsum. This technology is highly efficient, enabling low-cost removal of flue gas SO2. Moreover, it ensures that the plant remains compact and easy to maintain.
L&T-MHI Power Boilers Private Limited, a joint venture of Larsen & Toubro and Mitsubishi Power, Japan, has a technology licence agreement for Selective Catalytic Reduction (SCR) systems with Mitsubishi Power. The agreement is for design, engineering, manufacture, installation, commissioning, and sale of new boilers under BTG, EPC or SG packages or standalone SCR systems, and for existing and under construction boilers on exclusive basis in India. The SCR systems limit oxides of nitrogen (NOx) emissions.
For power plants above 300 MW capacities, L&T supplies Electrostatic Precipitators (ESPs), whose advanced technological features ensure energy efficiency and low downtime.
