flue gas heat recovery - Valmet

commonly used system for power generation from waste heat involves using the heat to generate steam in a waste heat boiler, which then drives a steam turbine. Steam turbines are one of the oldest and most versatile prime mover technologies. Heat recovery boiler/steam turbine systems operate thermodynamically as a Rankine Cycle, as shown in Figure 2.

Waste Heat and Water Recovery System Optimization for …

More production through flue gas heat recovery. There is a lot of energy in flue gas due to the water (30–60%) contained in the fuel and steamed in the boiler. This energy escapes into the environment when the water is not condensed back into a liquid. With Valmet's advanced flue gas condensing technology, you can recover this energy and use it, for example, to increase district heat capacity; save fuel; …
