Over recent years, the ever-increasing cost of fuel and the growing need to increase energy efficiency in the industry have led to a focus on "residual" energy, which was previously emitted into the atmosphere rather than being reused. Heat recovery projects are bespoke solutions which are developed based on the existing gas flow conditions (clean state, chemical composition, temperature, etc.), along with the final product best adapted to the customer's requirements. Some of the most common applications are:

• Preheating of combustion air, in order to save fuel.
• Heat generation in the form of saturated steam, hot/superheated water and thermal oil.
• Electricity generation.

In all cases, INNERGY has the know-how it has built up over several decades, allowing it to develop the complete project, from the engineering pre-feasibility phase through to the design, manufacture and commissioning of the most suitable equipment for each application.

Some of the main areas of application for INNERGY heat recovery technology are:

• Cement Industry Furnaces
• Glass Industry Furnaces
• Foundries and Steel Industry
• Ceramics Industry Furnaces
• Refineries
• Incinerators
• Biomass boilers
• Industrial boilers with burners fed with petroleum products
• Internal combustion engines and turbines.
