This device recovers the sensible heat in the hot air with temperature of 250 C to 450 C from a sinter cooler. It comprises mainly; a)boiler/economizer, b)pure water feed device, c)deaerator, d)steam drum, etc.
After heat exchange with sintered ore of 500 C to 700 C in the cooler, the exhaust gas is introduced to the boiler/economizer to generate steam and is recycled to the cooler.
This is a waste gas sensible heat recovery system from sinter cooler to generate electric energy. The system is composed of dust collector, waste heat recovery boiler as steam, circulation fan and power generator by steam turbine.
The values of cost and effect are obtained from a system configuration of two identical sintering machines, coolers each equipped with waste heat recovery boiler and one unit of electric power generator, to which the steam from two boilers is led.
An unit, Burner with Regenerator, ensures highly efficient, selectable thermal storage:
