Abstract

Abstract:

Improperly treated municipal sludge can cause irreversible ecological damage. Incineration is an effective method to mitigate the harm, but the incineration residue may contain heavy metals that are difficult to stabilize. To effectively address the issue and develop low-cost and environmentally friendly composite phase change thermal storage materials, it is proposed to use municipal sludge incineration residue as the skeleton material and potassium nitrate as the phase change thermal storage material. Five different mass ratios of sludge incineration residue/potassium nitrate composite phase change thermal storage materials were prepared using cold-pressing and sintering method. The macroscopic appearance, microscopic appearance, compressive strength, thermal stability, chemical compatibility, heat transfer and thermal storage properties, economic feasibility, and CO₂ emissions were characterized and analyzed. The results show that within the temperature range of 100-380°C, the optimal mass ratio of sludge incineration residue to potassium nitrate is 5:5 (sample SC3). The heat storage density is 322.45 J/g, latent heat is 41.75 J/g, and the maximum thermal conductivity is 1.04 W/(m?K). The compressive strength reaches 153.78 MPa. The two materials exhibit good chemical compatibility and are evenly distributed in sample SC3. Sample SC3 shows good high-temperature thermal stability after 1000 heating/cooling cycles. The thermal storage cost is 63.06 yuan/MJ. The total CO₂ emissions are 1083.53 kg/t, which is lower than the total CO₂ emissions of traditional skeleton material-based composite phase change thermal storage materials, indicating good environmental benefits and feasibility.

Key words: municipal sludge, skeleton materials, thermal energy storage, thermal stability, chemical compatibility
