Utilization of waste gas from DRI Kiln for power generation in Raipur, India

In the absence of this project, all the steam required for power generation would have been provided by the coal-fired AFBC boilers. Since no fossil fuel is consumed in the WHRB#2, the electricity generated through waste heat recovery will directly displace an equivalent amount of power from fossil fuel-based sources, thereby reducing greenhouse gas (GHG) emissions.

The WHRB#2 is expected to generate 10 MW of power, of which about 1 MW will be used for auxiliary consumption, resulting in a net supply of 9 MW. This will replace an equivalent baseline power generation, leading to annual emission reductions of approximately 48,951 tCO₂, and a total reduction of about 500,090 tCO₂ over a 10-year crediting period. The project thus contributes to climate change mitigation while promoting sustainable industrial growth.

Contribution to sustainable development

The project contributes to sustainable development across following key dimensions:

1. Social Wellbeing

• Generates employment opportunities for commissioning, operation, and maintenance in a rural and economically underdeveloped area.
• Enhances the professional skills of local people, contributing to long-term livelihood benefits.
• Implemented within the VGL plant premises without displacing local communities, thereby supporting inclusive development and reducing unemployment.

2. Economic Wellbeing

• Creates business opportunities for local contractors, consultants, and suppliers during both construction and operational phases.
• Contributes to local economic growth while supporting the nation’s increasing electricity demand and energy security.

3. Environmental Wellbeing

• Reduces thermal pollution by recovering and utilizing waste heat from DRI kiln flue gases that would otherwise be released into the atmosphere.
• Displaces fossil fuel-based power generation, thereby reducing emissions of SOx, NOx, and particulate matter, improving local air quality.

4. Technological Wellbeing

• Demonstrates efficient utilization of waste heat for clean power generation.
• Promotes energy conservation and adoption of waste-to-energy technologies, setting an example for sustainable industrial practices.
