The waste heat recovery market will reach $53.12 billion by 2018.

Europe dominates the market, accounting for a major share of about 38% in 2012. Asia-Pacific will experience highest growth rate of 9.7% in the next five years from 2013-2018. Key regions in Asia-Pacific market are China and India which will experience the highest installations of waste heat recovery systems.

Waste heat recovery system operates at lower temperature

Calnetix claims that its system is unique in that it can pull usable heat from a source with temperatures as low as 80°C, unlike other heat recovery systems that require much higher temperatures – typically engine exhaust gas temperatures. The Hydrocurrent system is said to convert excess waste heat into electric power without affecting engine performance, while still leaving sufficient heat in the jacket water to power a fresh water maker.

It has applied this technology to its WHR system, said be designed specifically for the shipboard environment, and to produce up to 125kW of power for the ship’s electric load from heat recovered out of the engine’s jacket water.

Opcon Powerbox produces electricity from waste water at a temperature range of 50-95°
– An average Opcon Powerbox generates 3 400 MWh of electricity per year
– 3 400 MWh = 340 cubic metres of oil = 2,100 barrels of oil

or what about the…


 Power-Pipe Drain Water Heat Recovery (DWHR) System from RenewABILITY Energy.

Is this a clever approach to recapture a significant amount of the heat (40%) that currently goes down the drain with the rest of the hot water?
