Tangshan Zhengfeng Iron & Steel Co. ordered three intelligent waste-heat recovery systems. Designed and supplied by Tenova, a Techint Group company, the iRecovery system is designed for use with electric steelmaking production, among other processes.

In 2017, the China Development and Reform Commission issued the Northern China Winter Clean Heating Plan. It mandated that, by the end of 2021, clean combustion of coal in thermal power plants would be used to provide 8 billion square meters of heating area. Estimates say this will account for nearly 40 percent of the total clean-heating area in northern China in 2021.

Recent energy cost increases and the introduction of anaerobic thermophilic processes as part of wasted industrial process and municipal-sludge digestion has prompted the use of heat recovery exchangers. 

Sigma Thermal, a manufacturer of biomass-fired energy systems and waste-heat recovery systems, is using solar power to supplement roughly half of its electricity needs during peak consumption times and nearly 100 percent in lower consumption periods.

A by-product of many industrial processes is high temperature air. Recovery and re-direction of the heat saves fuel, increases energy efficiency and reduces costs.

A commercially viable turbo-compression cooling system for ultra-low temperature waste heat recovery shows promise for industrial applications. For example, a dairy producer could transform the waste heat generated when they pasteurize their milk and put it to work chilling the milk.

With an ever-increasing focus on energy efficiency and improving system performance, industrial processors are looking for ways to achieve these goals while reducing costs and material usage wherever possible.

ElectraTherm shipped a Power+ Generator to the United Kingdom to generate fuel-free power from biomass.

Enerkem Inc.’s first full-scale commercial biofuel facility in Edmonton, Alberta, is producing methanol from household waste.

Companies in every sector of industry are continually searching for areas in their process to save energy, thus reducing costs and maximizing profits.
