Cement Plant Energy Saving & Emission Reduction
Waste Heat Recovery Power Plant
Comprehensive Waste Heat Recovery Power Plant Solutions for Cement & Other Energy-Intensive Industries
EPC WHR Solutions for Industrial Waste Heat Power Generation
AGICO provides waste heat recovery power plant solutions for cement plants. As an EPC project and equipment supplier for WHR power plants, our solutions are well-suited to meet the waste heat power generation needs of both new and existing cement plants. WHR plants typically have a power generation capacity ranging from 6 to 25 MW and support both PH and AQC waste heat sources. They can help industrial sectors such as cement plants, power plants, steel plants, and glass plants to save energy, reduce emissions, lower electricity costs, and enhance their competitiveness.
What is Waste Heat Recovery (WHR)?
Waste heat recovery, also known as WHR, refers to the process of recovering high-temperature waste gases and waste heat emitted during industrial production and converting them into usable energy forms through energy technologies. In cement plants, WHR involves collecting the high-temperature flue gas generated during the clinker production line and converting it into other forms of energy.
The Waste Heat Recovery System (WHRS) is a systematic device for waste heat recovery. The complete WHR process takes place in the WHRS, which not only recovers heat but also converts waste heat into steam for power generation or internal factory use.
Why does Your Cement Plant Need Waste Heat Power Generation?
The waste heat from cement clinker is enormous and stable, providing free energy
The exhaust gas from the kiln tail preheater and grate cooler is hot and comes in large volumes. The cement production line operates continuously throughout the year, providing a stable heat source for waste heat power generation.
Waste heat power generation can significantly reduce electricity costs
Cement plants have high electricity consumption, and electricity costs account for a large proportion of their total costs. Waste heat power generation does not require additional fuel and can directly offset part of the electricity consumption.
WHRS is one of the most cost-effective energy-saving projects
With a fast return on investment, WHRS generates electricity using waste gas, resulting in extremely low operating costs. Most projects can recoup their investment in just 2-3 years.

Solution capabilities for clinker production lines of 3000-10000t/d
Based on numerous operational case studies, AGICO has accumulated knowledge of boiler models, heating areas, heat exchanger layouts, and steam parameter ranges for different production capacity segments. Therefore, whether a customer has a medium-sized line of 3000 t/d or an ultra-large line of 10,000 t/d, they can quickly obtain the corresponding system selection.
01.
For common clinker production lines of 3000t/d, 5000t/d, 7000t/d, and 10,000t/d
we have developed mature configuration solutions, including the heat exchange area of the PH/AQC waste heat boiler, steam parameters, and steam turbine selection range, which can provide customers with reliable power generation forecasts and high availability operation data.
02.
Meanwhile, cement production lines built in different kiln types and at different times
vary greatly in terms of flue gas temperature, flow rate, and dust content. We will make customized adjustments to the boiler structure according to the actual working conditions to avoid problems such as insufficient heat absorption, severe ash accumulation, or excessive system resistance.
03.
For renovation projects of old cement production lines
we have extensive experience in complex spatial layouts. We can achieve compact layouts in limited areas, redesign flue routes, and preserve the existing structure to the maximum extent, thereby significantly reducing kiln downtime and renovation costs.
04.
In addition, for existing WHRS
we can provide a variety of power generation enhancement solutions, such as increasing heat exchange surface, optimizing air volume distribution, adjusting steam parameters, or adding online ash removal devices, which can typically bring an additional 5–15% of power generation.
Economic Benefits of Waste Heat Recovery Power Plants
In the global cement industry, waste heat power generation (WHR/WHRS) is widely recognized as one of the projects with the fastest return on investment and the most significant energy savings. Before choosing a waste heat recovery unit for power generation, customers are always most concerned with these two questions:
The following content is based on our practical project experience in multiple regions, including Asia, Africa, the Middle East, and Europe, and can help you quickly assess the investment value.
Typical Case: 5000t/d clinker production line with WHRS annual power generation
Taking a typical 5000t/d cement clinker production line as an example, after configuring WHRS, the power generation capacity, annual power generation, and corresponding electricity cost savings are as follows:
Configurable power generation capacity: 6–9 MW
Annual power generation: 45–65 million kWh/year
Local electricity price: 0.10–0.15 USD/kWh (example range)
Annual electricity savings ≈ $4.5 – $9.5 million
Since WHRS utilizes free waste gas industrial heat energy, requiring no fuel and resulting in extremely low operating costs, the typical payback period for such projects is approximately 2-3 years.
Actual data will vary depending on factors such as flue gas volume, boiler parameters, steam turbine efficiency, operating rate, and electricity prices. AGICO can provide you with accurate calculation models.
Estimation of investment scope for WHR project
| Clinker Line Capacity | Typical WHR Power Output (MW) | Investment Method |
|---|---|---|
| 3000 t/d | 3–5 MW | EPC package priced per MW |
| 5000–7000 t/d | 6–9 MW | EPC package priced per MW |
| 8000–10000 t/d | 10–15 MW | EPC package priced per MW |
Carbon emission reduction
According to international energy data, every 1 kWh generated can reduce CO2 by approximately 0.7-0.9 kg. Therefore, a 6-9 MW WHR system can reduce CO₂ by 30,000-55,000 tons per year. For cement plants, this will significantly improve:
