MECHANICAL,CSS,HTML: Waste Heat Boiler
Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of the

Development and Demonstration of Waste Heat Integration
Waste heat recovery units. Waste heat recovery units recover the heat from exhaust streams emitted by gas turbines, waste incinerators, CO boilers or any other fired equipment. They can be integrated into a complete process heat transfer system. These units can be installed in tandem with heaters and can be used to heat organic thermal fluids

Generating energy from waste, including anaerobic
The waste heat from this combustion process is captured to produce hot water for the space heating and warm water. This is the most common form of CHP boiler found to date. However the process is noisy and you have far less control over the hot water generated, so fuel cell and the Stirling engine CHP boilers are often preferred.
