Waste heat recovery unit - Revol

A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that recovers heat from hot streams with potential high energy content, such as hot flue gases from a diesel generator or steam from cooling towers or even waste water from different cooling processes such as in steel cooling . A Regenerative thermal oxidizer (RTO) is an example of a waste heat recovery unit that utilizes a

A high-temperature hybrid absorption-compression heat pum

9/15/2018 · An absorption-compression heat pump is a promising way to recover low-temperature waste heat efficiently in industrial applications. In this paper, an advanced ammonia-water absorption-compression heat pump is proposed to recover the sensible heat of flue gas below 150 °C to generate saturated steam at 0.5 MPa (151.8 °C).

Waste Heat Boilers | Industrial Efficiency Technolog

Capturing the waste heat can be done before the flue gas cleaning (with subsequent cleaning) or after gas cleanup (Worrell et al., 2008. p.60). The amount of heat that can be recovered is dictated by the outlet temperatures, which is limited to around 200°C in order to avoid condensation on boiler tubes (IPTS/EC, 2013, p. 316).
