Blast Furnace Gas Top Pressure Recovery Turbine – …
WebAbstract. Efficient removal of the dust from blast furnace top-gas is essential for energy recovery in a top-gas recovery turbine. In most blast furnaces de-dusting is achieved by two-staged cleaning systems, comprising of a first separator – a dust catcher or a cyclone - and a second cleaning stage which is usually a scrubber. WebOur top charging system is equipped with (1) raw material anti-segregation technology, and (2) an advanced top charging equipment. The introduction of these enables optimization of the gas flow within the furnace, bringing about a reduction in the molten pig iron unit requirement of $1.10–4.40/t-pig (CO 2 conversion: 17.2–69.0 kg/t-pig ... avast audio stuttering
