Enhancing our Sustainability Focus
Our innovative product solutions are enabling expansion into global markets and in meeting the customer requirements who are thriving for heat and power applications from diversified segments such as cement, steel, chemical, paper, distillery, sugar, and food processing followed by Waste-to-Energy (WtE) and Biomass industries.
FY 22 witnessed a huge scaling of our sustainable solutions in the emerging sectors of global energy transition.
A) 1st Waste-to-Energy (WtE) steam turbine generator commissioned in Germany
Given its energy-intensive production operations, a Germany-based globally reputed paper manufacturer reached out to TTL for a refuse-derived fuel (RDF) based power plant.
Our Support
- Delivered 15.6 MW steam turbine generator unit and auxiliaries
- Unit designed for thermal energy use in paper drying process
- Crafted to generate electrical energy to run the paper plant and to secure the energy needs of the neighbouring paper mill
Benefits
The excess heat from the paper drying process is fed through a district heating pipeline to heat the outdoor swimming pool run by the municipality
Impact
32 million cubic metres
Saving of natural gas & primary energy
55,000 tonness
Reduction in CO2 emission per year
B) Steam turbines for waste heat utilisation for South Korean steel major
During the year, TTL secured an order for three steam turbines from a world-renowned steel manufacturer in South Korea, amid stiff competition from German and Japanese companies. One of the subsidiaries of the steel conglomerate involved the TTL team from the stage of conceptualisation to the installation of three Coke Dry Quenching (CDQ) plants at its 2nd largest blast furnace steel mill. This is the largest steam turbine size (41 MW) order won by TTL under its own brand in the international market.
Our Support
- Incorporated one steam turbine generator, set to utilise waste heat from the blast furnace to generate electricity, in each of the CDQ plants
- Collectively, the three steam turbines will add 113 MW of power generation capacity to the steel plant
Impact
175 MW
Total installed power capacity in South Korea supplied by TTL
C) High pressure, high temperature inlet and Axial exhaust steam turbine for sugar cogeneration application
During the year, Triveni Turbines designed and supplied a 22 MW Axial exhaust steam turbine which is capable of operating at high pressure (up to 120 bar) and temperature (up to 540 deg C) for a sugar cogeneration unit in Karnataka. This has significantly reduced the civil cost of the power plant by effectively managing the construction space and for ease of operation by assembling all the components on a single floor.
D) Aftermarket expansion into Geothermal & other Renewables
We undertook several aftermarket projects in the renewables sector during the year, including geothermal projects, besides refurbishing of other turbomachinery products such as compressors, blowers and gas expanders.
We bagged repeat orders during the year from prestigious customers in Southeast Asia and East Africa for refurbishment of components in steam flow path for another geothermal turbine. This has consolidated our presence in the geothermal energy space as a reliable partner for refurbishing needs.
Our new rotor solution to old geothermal turbines in the global market lends a strong edge to the industry since the corrosive working environment in geothermal application necessitates advanced metallurgy and specially-coated blades.
Our spares and service business proactively offered solutions to customers during the year for converting extraction condensing turbines to back pressure, particularly for process cogeneration applications (e.g. Sugar), along with value-added proposition of efficiency improvement in some cases.
E) Reinforcing the defence sector
TTL is a regular supplier of specialty turbines for the defence industry. In FY 22, we developed a vertical steam turbine for marine application. As part of our continuous product upgrade process, we worked on innovative seal technologies, such as floating brush seals, abradable seals and bearing isolators that enhance turbine robustness and efficiency. TTL supported Indian Navy in their indigenisation efforts through refurbishment business by developing & supplying different sub-systems.
F) New Sub-3 MW catalogue product segment
TTL’s newly-developed Sub-3 MW, cost competitive, catalogue product segment will cater to the demand for PRDS (Pressure Reducing and De-superheating System) replacement in Rice Mill, Palm Oil Mill and other industries. This product range will be marketed through our channel partners.
Making strides in oil & gas industry
We offer steam turbine solutions that meet the challenging requirements of the Oil & Gas industry. We made significant strides in this area during FY 22, winning several key orders on the strength of our ability to supply energy-efficient API (American Petroleum Institute) 611 and 612 compliant steam turbines, ranging from 10 kW to 100 MW. These order wins further underscore our deep domain expertise to provide retrofit solutions to other turbo-machinery such as compressors, blowers, gas turbines.
Internalising the sustainability culture
Even as we continue to support our customers in driving their sustainability journey, we, at TTL, also remain focussed on building sustainable operations at our own manufacturing facilities.
Our plants are eco-friendly, with adequate green cover, dotted by large trees, natural landscaping, rainwater harvesting facilities, solar panels for harnessing renewable energy, among others.
It is our constant endeavour to improve our environmental performance by focussing on conservation of water, energy and materials, as well as waste reduction.
Peenya factory has installed solar panels of 300 KW capacity, with net metering facility to export surplus energy
Rainwater harvesting facilities at our plants help maintain the natural water bodies and enable recycling of water for garden maintenance.
Energy-efficient LEDs are being introduced in a phased manner to replace the conventional compact fluorescent lamps/ fluorescent lights.
Variable frequency drives are used in power-intensive areas, such as cranes, boilers etc., to reduce energy consumption.
