Steel & Metals Solution
Unlock the Power Hidden in Your Process Heat.
Recover high and medium-temperature waste heat from EAF, blast furnaces, BOF, reheating furnaces, sinter plants, and rolling mills to generate captive electricity and cut operating costs.
Executive Summary
Unlocking value from high-temperature steelmaking streams.
Steel and metal manufacturing is among the most energy-intensive industrial sectors. Every stage of production—from ironmaking and steelmaking to rolling and heat treatment—generates enormous amounts of high-temperature waste heat. In many facilities, this valuable thermal energy is released into the atmosphere without being recovered.
This untapped energy represents a major power asset.
At Datre Renewable Energy, we help steel and metal manufacturers capture this untapped energy and convert it into clean, reliable electricity using Organic Rankine Cycle (ORC) technology—reducing energy costs, improving operational efficiency, and supporting sustainable industrial growth.
Heat Source Mapping
Where Does Your Plant Lose Energy?
Throughout the steel production process, substantial amounts of recoverable heat are generated from furnaces, hot gases, and cooling systems.
| Process Area | Typical Heat Source | Temperature Range |
|---|---|---|
| Electric Arc Furnace (EAF) | Furnace Exhaust Gas | 400–900°C |
| Blast Furnace | Top Gas & Exhaust | 150–350°C |
| Basic Oxygen Furnace (BOF) | Converter Gas (Post Heat-Recovery Boiler) | 300–700°C |
| Reheating Furnace | Flue Gas | 350–700°C |
| Sinter Plant | Exhaust Gas | 200–400°C |
| Rolling Mill Cooling | Hot Cooling Water | 40–90°C |
Disclaimer: The temperatures, recovery potential, and energy estimates presented on this page represent typical industry values and are provided for illustrative purposes only. Actual recoverable energy depends on plant design, operating conditions, production capacity, heat source characteristics, and overall system configuration. A detailed engineering assessment is recommended to determine the feasibility and performance of an Organic Rankine Cycle (ORC) system for your facility.
Did you know?
Steel manufacturing can lose 20–40% of its input energy as waste heat, depending on the production process, furnace type, and operating conditions. A significant portion of this energy can be recovered and converted into useful electricity.
Operating Impact
What Does This Mean for Your Plant?
Every tonne of steel produced carries valuable thermal energy that is often discharged unused.
Higher Electricity Purchases
Heavy reliance on grid power inflates monthly utility expenses and grid surcharges.
Increased Fuel Consumption
Unrecovered furnace heat forces higher fuel combustion per tonne of steel produced.
Greater Operating Costs
Thermal energy wasted through stacks expands operational expenditure.
Lower Overall Efficiency
Discharged flue gas and cooling heat degrade facility thermal-to-power energy balance.
Higher Carbon Emissions
Relying solely on grid power inflates the environmental carbon footprint per tonne produced.
Output & Financial ROI
Typical Energy Recovery Potential
Datre manufactures standard 10 kW, 50 kW, and 500 kW ORC systems that scale modularly for steel mills and metal plants of any size.
| Process Heat Stream | Power Output |
|---|---|
| Small Rolling Mill / Process Exhaust | 10 kW – 50 kW |
| Medium EAF / Reheating Furnace Stream | 50 kW – 500 kW |
| Large Steel Plant / Blast Furnace Flue | 500 kW |
| Integrated Steel Manufacturing Complex | 500 kW – 10 MW+ |
Imagine the Value for a 500 kW System
Suppose a 500 kW Datre ORC System operates 8,000 hours per year, generating approximately 4,000,000 kWh (40 Lakh units) of electricity annually.
If industrial grid electricity costs average ₹7–9 per kWh, the generated captive power represents:
Instead of allowing valuable thermal energy to escape into the atmosphere, your plant can convert waste heat into reliable electricity using modular Datre 10 kW, 50 kW, and 500 kW ORC units to significantly reduce dependence on grid power.

- High operational reliability — Designed for heavy duty industrial steel mill operation
- Low maintenance requirements — Non-corrosive, non-eroding working fluid
- Continuous industrial operation — Operates seamlessly 24/7 alongside production
- Long equipment life — Proven 20+ year lifecycle with stable performance
Qualification
Is Your Plant a Good Candidate?
Your steel or metal manufacturing facility may be suitable for waste heat recovery if you operate:
If your plant continuously produces hot exhaust gases, furnace heat, or high-temperature process streams, there is a strong possibility that recoverable energy is currently being lost.
