    1. 277. REDUCING THE COST OF BF TOP GAS DUST HANDLING, WITH PRACTICABLE PAYBACK
      Mr Robert Mawer (Primetals)

      Environmental control in coke and ironmaking
      Oral Presentation
      The majority of existing blast furnaces plants use a dustcatcher as the primary process for removal of the process dust from the top gas. In recent years, there has been a trend to replace the dustcatcher with a cyclone: increasing the efficiency of dust removal, increasing the dry dust recycle to (for example) the sinter plant, and reducing the sludge volume generated from wet gas cleaning....

    2. 273. NEW EFFICIENCY IN IRONMAKING FACILITIES
      Mr Andreas Steinwandter (Primetals Technology Austria GmbH)
      27/09/2018, 13:00
      Environmental control in coke and ironmaking
      Oral Presentation
      The demand for increasing energy efficiency is one of the global megatrends of our time. Although the steel industry suffers from a volatile economic environment, steel plant operators are interested to find opportunities for sustainable cost reduction. Steel mills are trying to cut electrical power and energy costs as these are among the biggest cost factors that can be influenced. The...

    3. 239. ILTEC – HIGHLIGHTING POTENTIALS AND ELIMINATING CONCERNS REGARDING THE SAFE AND WATER-FREE COOLING TECHNOLOGY
      Dr Martina Hanel (Mettop GmbH)
      27/09/2018, 13:20
      Environmental control in coke and ironmaking
      Oral Presentation
      It is the increasing demand for an economic and cost saving operation mode that requires effective cooling in order to achieve low refractory wear and good furnace lifetime, which is making cooling technology an important aspect of furnace operation. In addition, the requirements for safety are getting more and more into focus. However, the use of water - today’s standard cooling medium - has...

    4. 225. BFG DRY DEDUSTING SYSTEM AT POSCO GWANGYANG NO.1 BF
      Mr Ki-Gun Hong (POSCO)
      27/09/2018, 13:40
      Environmental control in coke and ironmaking
      Oral Presentation
      Gwangyang No.1 blast furnace blowed in 2013 with 6,000㎥ inner volume (first half in 2017, Po 2.36t/d/㎥, RR 488.0kg/t-p), and dry-type dedusting system is installed at that time. The introduction background is electricity cost saving through TRT power generation and reducing the amount of waste water discharge, compared with wet-type dedusting system. The dedusting system of Gwangyang No.1 BF...

    5. 102. MIGRATION OF ORGANIC SULFUR IN NANTONG AND LAIGANG COAL WITH ADDITION OF NaOH-H2O2 UNDER MICROWAVE TREATMENT
      Mr Yue Wu (Chongqing University)
      27/09/2018, 14:00
      Environmental control in coke and ironmaking
      Oral Presentation
      Nantong coal (NTC) and Laigang coal (LGC), the two typical high-sulfur coking coal in China, were investigated on their desulfurization processes with the addition of NaOH-H2O2 under microwave treatment. X-ray diffraction (XRD), inductively coupled plasma (ICP) and fourier transform infrared (FT-IR) were performed to unravel the migration of organic sulfur in the two coal. In addition, the...
