Daikin Gas Furnace Reviews- The big difference between the lower-tier units and higher-tier units are the heat exchangers. For extra efficiency, the higher-grade units have secondary heat exchangers to absorb extra heat from the combustion gases before they are vented outside. Other things add t...
The thermal profile and the mass flows are also significant as they can have an effect on the refractory, the furnace's life-time, the fuel efficiency, and the chemistry within the furnace. An overall method for determining the thermal profile and the mass and energy for each flow within ...
Currently, approximately 95% of hot metal is produced by the blast furnace ironmaking process, which is also predicted to be the largest single ironmaking process until 2050 because of its advantages in production cost and efficiency. Therefore, replacing fossil-based fuels with H2 as the reductant...
This chart allows a comparison between carbon capture and storage (CCS) and carbon capture and utilization (CCU) options. As expected, high electricity costs tend to favor the CCS case with respect to the CCU case. In the higher electricity cost scenario (Fig. 7a), with methanol selling ...
FIG. 7 is a graphic chart showing high temperature properties of materials which is expected to be applied as the above-mentioned dividing members, and shows the change of their thermal expansion coefficients with temperature. Four different materials are shown for comparison: SUS310S, Inconel 600 ...

Figure 8. Comparison chart of optimal setting prediction results of multiple models: (a) 11/23∼11/26 comparison; (b) 12/25∼12/28 comparison. To better illustrate the advantages of CNN-LSTM-A, we also test on the online dataset of 12.25∼12.28. Figure 8b and Table 5 show the...
Figure 9. Comparison chart of different methods for measuring blast furnace burden level under normal working conditions. Figure 10 shows the comparison between the radar data, the detection data of the traditional RBFNN and the ESST-RBFNN under abnormal working conditions. Under this abnormal workin...
By posing the question of what will be the definition of sustainable development in the future, it can almost be seen that the principle of “no waste” and the production of new materials with less of a negative environmental impact will have a high pri
Campos [2] reported an exergy-based comparison between BFG-fueled combined cycle plants and steam cycle plant configurations, providing a method of direct combustion of blast furnace gas for power generation. Campos [3] compared the efficiency of combined cycle and Rankine cycle in BFG utilization,...
