  • Energy Conservation and Emission Reduction-Innovation Goal for Cupola
    Foundry Equipment and Technology, 2020
    Co-Authors: Jiang Yong-lu, Ltd Qinghuangdao
    Abstract:

    Aim at the problems of serious hot Waste and Pollutant emission in cupola, the air -cooling and strengthened - preheating single row twister air-supplying cupola was developed. In this cupola, water cooling was replaced with air cooling, straight preheating zone replaced with bidirectional taper preheating zone, two or multi-row tuyere replaced with single-row tuyere, linear air supplying replaced with cyclone supplying.The practice show this cupola not only bring obvious economic benefits to the consumer but also save energy, reduce emission and protect environment.

  • Water Hyacinth–Cement Composites as Pollutant Element Fixers
    Waste and Biomass Valorization, 2019
    Co-Authors: Adela Salas-ruiz, María Mar Barbero-barrera, M. I. Sánchez De Rojas, Eva Asensio
    Abstract:

    Water hyacinth (WH) or Eichhornia crassipes is one of the 100 most dangerous invasive species in the world. Currently, WH has enormous negative impacts on various ecosystems, and its eradication poses a seemingly impossible challenge. Physical extraction has been found to be an adequate process for controlling the spread of WH, but sustainable Waste management of WH has not been achieved due to its ability to absorb Pollutants. In this study, preliminary research on the possibility of using water hyacinth root ash (WHRA) as an alternative to pozzolans in cement matrices in order to fix these Pollutants is presented. Characterization of the samples was carried out by XRF, SEM, BSE, EDX, ICP-OES, XRD and FTIR. A complete study of the pozzolanic activity and hydrated products of WHRA was conducted. Mechanical characterization of 25% replacement mortars was evaluated, and a Pollutant fixed/leaching characterization was made. The results indicate that WHRA reacts with calcium ions and other Pollutants. Thus, WHRA–cement mortars can be utilized as a green method of fixing the Pollutants present in WHRA. The incorporation of WHRA is suitable as a cement addition for non-structural constructive elements, such as pavements or precast products. WHRA–cement composite is a low-cost, greener material, which promotes the reuse of Waste and Pollutant elimination.Graphical Abstract
