Waste Heat Recovery Boilers & Fired Boilers for Chemical Industry

Thermal System provides combined heat and power (CHP) unit, also known as a cogeneration unit, which can be used in conjunction with a waste heat recovery boiler for the chemical industry to increase energy efficiency and reduce energy costs. The CHP unit generates electricity and heat simultaneously by using the waste heat from the combustion process. The hot flows of flue gas from the upstream combustion processes are conducted into the waste heat recovery boiler and used to generate steam or hot water. This steam or hot water can then be used to power the CHP unit, which generates electricity.


The waste heat recovery boiler for chemical industry is designed with a compact and modular design, making it a suitable option for both new plants and modernisation projects. Its compact size allows for easy installation in the existing facility infrastructure, while its modular design allows for flexibility and easy maintenance.

By using a waste heat recovery boiler in conjunction with a CHP unit, it is possible to significantly improve energy efficiency in the chemical industry, reducing energy costs and emissions.
