Comparative Analysis and Application on Mobile-Heating Technology of Regenerative Energy

The waste heat resource of iron and steel industry was the research object. The economical and technical of direct heating, sensible heat storage and latent heat thermal storage were compared. The result shows that using phase change materials (PCM) as storage materials, energy storage density is higher, cost and exergy loss is lower and the discharge of air pollutants can be reduced, which is compliance with the requirements of conservation and reduction of pollutant emissions and has a broad application prospect.
