Flue Gas Waste heat recovery (WHR) generally involves capturing and reusing the heat energy in industrial processes’ flue gases for the purposes of local heating, cooling or generating mechanical and electrical work. Most waste heat streams are otherwise exhausted into the atmosphere, sometimes incurring costs to cool them down to prescribed temperatures.

Efficiency improvements resulting from WHR in industrial furnaces can be quite significant. The waste heat is considered an emission-free substitute for increasingly costly fuels or electricity. To date, a number of highly efficient technological solutions have been extensively developed to recover heat energy for a wide range of industrial furnaces including smelters, roasters, ovens, kilns etc.


Robust Technologies

In a bid to provide local manufacturers with personalized WHR solutions that conform to all their requirements, Dickinson Group of Companies, collaborates with leading world-class WHR technology suppliers around the world. The resulting offering is a complete array of highly robust and cost effective solutions which comply with stringent quality specifications and high safety standards.

Part or Full Project Finance

Research has shown that a number of commercially-viable WHR and cogeneration projects in the region remain un-implemented due to funding issues. Subject to projects meeting well defined financing requirements, Dickinson Group of Companies is in a position to organise off-balance sheet financing for the implementation of WHR Projects.

Flexible Business Models

To further enhance the viability of WHR projects, the company has packaged several highly innovative solutions within the context of flexible business models. The WHR p+rojects are developped in the following business models; Turnkey Engineering Procurement & Construction (EPC), Build Operate & Transfer (BOT) and Power Purchase Agreements (PPA). The last two models may allow industrial furnace operators to enjoy benefits from WHR solutions without having to directly deal with the major obstacles to WHR as follows:

  • The models allow WHR systems to be implemented without the client laying out capital

  • The models provide flexibility in the construction, operation and maintenance of the WHR systems, ultimately leaving the client to focus on their core business


The major benefits of waste heat recovery may be summarised as follows:

  • Lower electricity bills; significantly lower utility power electricity consumption.

  • Enhanced power plant reliability; powering the critical drives from the WHR power plant avoids stops linked to grid issues.

  • Mitigation of the impact of future electricity prices increases.

  • Sustainability: lowered carbon footprint.

  • 12 hour tax rebate at R0.95 / KWh during the first year (in South Africa).
