The molten blast furnace slag (BF slag) is discharged at the temperature of about 1400-1550 °C, which contains a large amount of heat. At present, water quenching is the main technology to treat the BF slag, but this method not only consumes a huge amount of water, but also fails to recover the waste heat. Compared with water quenching, the dry centrifugal granulation has obvious advantages. There is no water consumed and the waste heat can be recovered efficiently, thus this technology has great potential. This technology mainly contains two processes: the granulating process and the heat recovery process. The present development statuses on those two processes are summarized respectively and the prospect of dry centrifugal granulation technology is forecasted.

This paper presents energy analysis, thermodynamic calculation and exergy analysis for waste heat power generation system of Organic Rankine Cycle based on the first and second laws of thermodynamics. In order to improve system performance, for low-temperature waste heat of 120°C and R245fa organic working fluid, using Aspen Plus software conducted simulation, optimization and improvement. Results from these analyses show that decreasing the expander inlet temperature, increasing inlet pressure of the expander, and adding regenerative heater can increase thermal and exergy efficiencies, at the same time reduce system irreversibility.
