Capturing and Reusing Waste Heat

Pairing ORC technology and heat exchangers can help some facilities capture otherwise lost thermal energy in bulk solids materials to reduce energy consumption and generate electricity.

No Comments

Many of the world’s industries have been recovering heat from exhaust gases for decades. For instance, in both metal and plastics processing, producers often recover heat from flue gases emitted from the production processes. The recovered heat can be reused or converted into electrical energy or steam.

Waste-Heat Recovery from Power Plants for District Heating

Applying a centrifugal heat pump and absorption heat pumps to recover waste heat from the cooling water of the power plant steam condenser allowed one city to avoid the cost and emissions of coal-fired district heating.

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.

System Turns Low Temperature Waste Heat into Cold Water

February 28, 2018
No Comments

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.

Heat Recovery for Process Efficiency

Recapturing waste heat allows you to capture thermal energy you would otherwise let escape up the stack and put it to work in your process. Air-to-air heat exchangers provide an effective means of capturing this otherwise lost resource.
Jessica Irons, Honeywell
February 15, 2018
No Comments

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.
