waste heat boiler system for reheating furnace

Reheating furnaces – reining-heisskuehlung.de

The heat recovery at reheating furnaces can be significantly increased by using additional waste heat recovery systems in the offgas downstream the recuperator. The off gas is cooled down to a set lower temperature in waste heat boilers before it is discharged to atmosphere via the downstream stack, so the energy is not wasted.

Waste Heat Boilers – Clarke Energy

Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as ‘high grade heat’, contrasting to ‘low-grade heat’ available from the generator cooling circuits. This high temperature and flow makes it well
