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

the boiler over the boiler control room. The feed water tank is provided with a level control system by which the level is maintained constant. The level control system comprises a level transmitter, Control valve, and its isolation & bypass valves. The status on % opening of the feed control valve is available in DCS through the position transmitter.

Effective heating controls are a vital part of an efficient boiler-powered central-heating system. Clever use of controls can help you minimise energy consumption by ensuring each room is at the right temperature for comfort. This will keep your home cosy and cut your energy bills. Will your boiler let you down during a cold snap or mid-shower?
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.
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 )
