Heat recovery boilers are also often found in association with high temperature processes such as steel and glass making. It is not uncommon for these boilers to receive additional heat by supplementary firing of other by-products or by burning gas or light oil to raise the boiler inlet gas temperature to a level commensurate with the desired

Feb 28, 2014 · Advantages of a Heat Recovery System Of course, the main benefit of heat recovery is that there's less wasted heat, which means less money wasted on fuel costs. With a new ventilator, you can keep your windows closed, seal up drafts, insulate your home and still breathe fresh air every day.

The remainder of the heat in the steam is retained in the condensate as the sensible heat. Now this condensate is fed to the Boiler along with the feed water coming from the feed pump, so the net temperature of the water entering the Boiler shell is way beyond the one without the Condensate recovery.

Heat recovery from Boiler Blowdown Increase energy efficiency and cut costs by recovering heat and water from TDS blowdown Steam boilers need to be blown down to control the level of Total Dissolved Solids (TDS) in the boiler water. Usually, a TDS system opens a valve to discharge boiler water when the conductivity rises above a pre-set limit.

This is an iron-based fouling found in a hot water loop in a commercial building. The fouling came off easily with low pressure water in the field. the first place to start is with the fluid containing the scaling agent. These mineral scales can come from some boiler treatment and cooling tower chemicals, well waters, or any natural brine

Blowdown Heat Recovery Introduction. All steam boilers must blowndown to reduce the amount of TDS in the boiler water. See Blowdown However, along with the solids, boiler chemicals and thermal energy is lost; blowdown heat recovery systems cannot recover the chemicals, but they do recover up to 90% of the heat energy that would otherwise be lost down the drain.

Aug 05, 2016 · Waste Heat Recovery System. Here is the point wise explanation of this: Fuel is burnt in the engine. And the exhaust goes out of it. Although the energy from fuel released in the engine is already used by the engine, but the heat is still there in the exhaust. Now this heat in the exhaust can be used to heat the water and generate steam.
