Industrial plants across India are under increasing pressure to reduce fuel consumption, cut emissions, and move toward renewable and efficient energy solutions. In this transition, one technology has proven to be a game-changer:
⭐ Waste Heat Recovery Boiler (WHRB)
A waste-heat-recovery-boiler (WHRB) captures heat that would normally escape from industrial processes and converts it into useful steam or power — reducing fuel cost, enhancing plant efficiency, and supporting India’s sustainability goals.
With rising energy prices and strict government compliance requirements, industries are now actively searching for the best waste heat recovery boilers that deliver measurable results.
Among the leading manufacturers stands Cheema Boilers Limited (CBL), headquartered in Mohali, Punjab — a trusted Indian boiler brand providing WHRB solutions for cement, steel, power, chemical, and process industries.
What is a Waste-Heat-Recovery-Boiler?
A waste-heat-recovery-boiler is a specially designed industrial boiler that uses wasted heat energy from industrial operations instead of burning additional fuel.
This unused heat is commonly released from:
Furnace flue gases
Cement kiln exhaust
Gas engine exhaust
Steel reheating furnaces
Chemical reaction outlets
Gas turbine flue gas
Biomass or oil-fired systems
Instead of letting this heat escape through chimneys, WHRB technology traps it and converts it into steam or electricity — creating a secondary source of energy at no extra fuel cost.
Why Industries Need Waste Heat Recovery TODAY
Industries in India face challenges related to:
❗ Rising fuel cost (coal, gas, oil, diesel)
❗ High electricity bills
❗ Mandatory emission control regulations
❗ Sustainability reporting requirements (ESG, ISO, CSR)
❗ Competitive global market prices for exports
In this scenario, a waste-heat-recovery-boiler offers a guaranteed and proven solution:
📉 Reduces plant operating cost
📈 Increases energy efficiency
🌍 Supports carbon neutrality and green energy goals
♻ Uses existing heat — no new energy source required
No wonder WHRBs are now installed in:
✔ Cement plants
✔ Steel rolling mills
✔ Sponge iron industries
✔ Glass factories
✔ Refineries
✔ Chemical plants
✔ Gas engine power plants
✔ Fertilizer industries
✔ Textile processing units
How Does a Waste-Heat-Recovery-Boiler Work? (Step-by-Step)
Here’s a simple explanation:
Step 1: Industrial process releases hot exhaust gas
Example: A cement kiln releases exhaust gases at 300°C–400°C.
Step 2: WHRB captures this heat instead of letting it escape
The system is placed directly in the flue gas line.
Step 3: Heat is transferred to water
Water inside evaporator tubes absorbs heat.
Step 4: Steam is generated
The boiler produces steam without burning fuel.
Step 5: Steam is used for:
✔ Power generation through a turbine
✔ Heating processes
✔ Running captive power plants
✔ Driving turbines for industry operations
Result:
✔ No fuel used
✔ Zero added emissions
✔ High savings
Types of Waste Heat Recovery Boilers
Waste-heat-recovery-boilers come in multiple designs:
Fire Tube WHRB
Hot gas passes through tubes, surrounded by water.
Water Tube WHRB
Water flows inside the tubes, gas surrounds them — most efficient and widely used for high-pressure steam.
Heat Recovery Steam Generator (HRSG)
Used with gas turbines and engines.
Composite Waste Heat Boilers
Designed for dual heat sources.
Hybrid WHRB
Combines heat recovery + small auxiliary burner for backup.
Cheema Boilers manufactures customized WHRBs depending on:
✔ Process gas temperature
✔ Pressure requirement
✔ Steam capacity
✔ Industry application
Key Benefits of Waste Heat Recovery Boiler
Saves Fuel Cost
Up to 30–60% reduction in fuel use depending on plant setup.
Reduces Electricity Bills
Steam converts into captive electricity — saving crores every year.
Improves Efficiency
Plant overall thermal efficiency increases up to 90%.
Cuts Carbon Emissions
No additional combustion = significant emission reduction.
Supports ESG & Net-Zero Goals
WHRB installations qualify for CDM credits & sustainability KPIs.
Less Reliance on Grid Power
Power self-generation protects against power cuts & tariff hikes.
Faster ROI
Investments are recovered in 1.5 to 3 years through fuel savings.
Waste Heat Recovery Boiler Efficiency
Efficiency depends on:
🔹 Gas inlet temperature
