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.

ObjectiveTechnology
The heat recovered by inert gas is used to produce steam, which may be used on-site or to generate electricity. Hot coke from the coke oven is cooled in specially designed refractory lined steel cooling chambers by counter-currently circulating an inert gas media in a closed circuit consisting of 1) cooling chamber, 2) dust collecting bunker, 3) waste heat boiler, 4) dust cyclones, 5) mill fan, 6) blowing device (to introduce the cold air from the bottom), 7) circulating ducts.

Objective
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. -
Objective
This system generates electric power by employing the heat and pressure of blast furnace top gas to drive a turbine generator. After the blast furnace gas is used in power generation, it is used as a fuel in iron and steel manufacturing processes. Blast fumace gas (BFG) has a pressure of 0.2-0.236 MPa (2-2.41 kg/cm2) and temperature of approx. 200 C at the fumace top.

ObjectiveTechnology
The power consumption level of vertical roller mill is lower than that of tube (ball) mill. The feed is ground between the disc table and the rollers which are hydraulically pressed against a disc table. The remaining time of raw materials in vertical roller mill is much shorter than that in tube (ball) mill; therefore, the crushing process and mixing process became more harmonized and this contributes to quality control.
