Industries in India are growing at a rapid pace—but so are their fuel costs, operational expenses, and pressure to meet sustainability targets. Whether it’s a cement plant, steel unit, refinery, fertilizer industry, textile mill, or chemical plant, one challenge remains the same:
Energy is the biggest operational cost in Indian industries.
Fuel prices have increased sharply in the last decade. Electricity tariffs continue to climb. Environmental regulations are becoming stricter. Competitors are getting leaner and adopting efficient technologies faster.
In such a scenario, the biggest question for India’s industrial sector is:
**How can we cut energy costs without affecting production?
The answer: Waste Heat Recovery Boilers (WHRBs).**
Cheema Boilers, Mohali—one of India’s trusted industrial boiler manufacturers—has been designing high-efficiency WHR boilers and industrial waste heat recovery boiler systems that help industries save crores every year.
This blog explains, in simple + technical detail, how Waste Heat Recovery Boilers reduce energy costs, why they are becoming mandatory in 2025, and how industries across India are benefiting from them.
What Is a Waste Heat Recovery Boiler (WHRB)?
A Waste Heat Recovery Boiler is a specially engineered boiler that captures the heat normally lost into the atmosphere from:
✔ exhaust gases
✔ flue gases
✔ kilns
✔ furnaces
✔ chimneys
✔ chemical reactions
✔ turbine exhaust
✔ drying, roasting, calcination or melting processes
and converts it into useful steam or power.
Instead of generating heat using expensive fuels (coal, gas, oil, FO, LDO, HSD), a WHRB recycles the heat that your plant is already producing but wasting.
This makes WHRB one of the most cost-effective and environment-friendly steam generation technologies available today.
Why Indian Industries Waste So Much Heat?
Most industries in India operate energy-intensive systems such as:
Rotary kilns
Sponge iron kilns
Boilers
Thermal oxidisers
Diesel or gas engines
Gas turbines
Furnaces (aluminium, steel, glass, copper)
Incinerators
Calcination units
Dryers
All these systems release extremely hot flue gases—often between 250°C to 950°C.
This heat is normally allowed to escape the stack unused.
In many plants, 30–40% of total heat produced is lost into the environment.
This is equivalent to burning money.
A high-efficiency WHRB by Cheema Boilers Mohali captures this heat and converts it into:
Steam
Hot water
Power (via steam turbines)
Pre-heated air
Pre-heated feed water
This directly reduces fuel consumption and operational cost.
How WHRB Boilers Reduce Industrial Energy Costs (Step-by-Step)
Below is a detailed breakdown of how WHR boilers drastically reduce energy expenses in Indian industrial plants:
A. They Reduce (or Eliminate) Fuel Consumption
A conventional boiler burns fuel to produce steam.
A WHRB produces the same amount of steam—but without burning fuel.
This means industries cut:
✔ Coal consumption
✔ Diesel / FO / LDO usage
✔ Gas consumption
✔ Biomass cost
✔ Electricity usage (for captive steam generation)
Industries typically save:
15–45% of their monthly fuel bill depending on process.
B. They Reduce Electrical Energy Consumption
Many plants buy costly electricity or run captive power plants.
A WHRB:
Generates free steam →
Drives steam turbine →
Produces free electricity
Industries using WHRB for power generation save between:
₹30 lakh/month to ₹2 crore/month
depending on size.
C. They Reduce Cooling Costs
Before WHRB systems existed, plants cooled hot gases using water, ID fans, or cooling towers.
This wasted water + power.
A WHRB absorbs that heat—reducing cooling load and saving:
✔ Water
✔ Pumping electricity
✔ Cooling tower maintenance cost
✔ Fan power
D. They Improve Production Efficiency
Recovering heat stabilises temperature inside the plant, improving:
Kiln efficiency
Turbine efficiency
Heater performance
Furnace quality
Chemical reaction rates
This leads to:
✔ Fewer breakdowns
✔ Less scale formation
✔ Longer refractory life
✔ Better product quality
✔ Higher production output
E. They Reduce Carbon Emissions (ESG Compliance)
Every tonne of fuel saved reduces CO₂ emissions.
A typical WHRB system reduces:
5,000 – 50,000 tonnes of CO₂ per year.
This helps industries meet:
Government norms
ESG reporting
Sustainability goals
Export compliance
F. They Lower Overall Operating Cost (OPEX)
WHRBs reduce:
✔ Fuel cost
✔ Electricity cost
✔ Cooling cost
✔ Maintenance cost
✔ Water cost
✔ Pollution control cost
This is why WHRBs offer the fastest ROI among industrial systems—usually in 1–3 years.
