waste heat recovery boiler

Utilizing waste heat in cement production

Cement production emits a lot of heat. Instead of letting it go to waste, said heat can be utilized. Not only does this concept make cement plants more sustainable, it also makes them more self-sufficient in terms of energy supply.

To make cement plants more self-reliant in meeting their power needs, we offer a customized one-stop solution with complete Waste Heat Recovery (WHR). We deliver the design, engineering, manufacturing, and supply of complete power plants with Waste Heat Recovery for cement plants.

How does the Waste Heat Recovery solution work?

Especially in the preheater and cooler section of cement manufacturing, a considerable amount of heat is generated. Our innovative process uses this "waste heat" generated during cement production to operate power plants which in turn supply the cement plant with energy.

Our in-house technology for Waste Heat Recovery Boilers

Our WHR boilers are natural circulation boilers, well proven in many plants and under difficult conditions. Our boilers have a robust and clear design that can fulfill the demands of power stations or industrial applications. Another advantage of our waste heat boilers is that steam can be generated, which in turn drives the steam turbine generator to produce electrical power for your cement plant.

Everything from one source

We, at thyssenkrupp Industrial Solutions, supply the engineering and procurement of the turbine-generator and BOP (Balance of Plant) packages of the power plant and handle system integration of the mechanical, electrical and instrumentation equipment.

What about operating costs of Waste Heat Recovery solutions?

The power generated in the waste heat recovery power plant is supplied at negligible operating costs. Since no fuel has to be burned, the process reduces the costs of energy-intensive cement production.

In addition, the power plant is absolutely environmentally-friendly, as heat emissions into the atmosphere are significantly reduced, limiting the greenhouse effect.
