Waste heat recovery unit - Wikipedia

A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency. The WHRU is a tool involved in cogeneration.Waste heat may be extracted from sources such as hot flue gases from a diesel generator, steam from cooling towers, or even waste water from

Waste Heat Recovery Systems for Steam Boilers

In a steam boiler the heat from the flue gas is transferred to the water, which then turns into steam. Downstream of the boiler the flue gases are still high in temperature and are typically 50ºC or more above the steam temperature. Flue gas heat exchangers downstream the boiler can recover this waste heat and improve the boiler fuel efficiency.

Active Fault Tolerant Control System for the Measurement

13/03/2018 · Besides the security system, a boiler comes with a water-level control system in the steam drum 1,2,4 and a three-element control system, as presented in Figure 2. To eliminate the control systems faulty operation, three-element systems are used, and the additional feeds to the control system are signals from the flow transducers of steam ( F D ) and feed water ( F W )
