Coal ash is a byproduct of mineral coal combustion in thermal power plants. This residue is responsible for many environmental problems because it pollutes soil, water, and air. Thus, it is important to find ways to reuse it. In this study, coal fly ash, obtained from the Presidente Médici Thermal Power Plant, was utilized in the preparation of ceramic supports for the immobilization of the ...
ASH Industrial Process and Chemical Pumps are horizontal, self-priming, multi-stage side channel pumps with open vane wheel impellers that handle entrained gas during normal duty. A special bearing was developed for compensation of the axial forces occurring in case of high nominal pressures.
Jun 03, 2020· The iron and steel industries need to reduce their dependence of finite natural materials and reduce their CO 2 emissions. The pulp and paper industries need to reduce the amount of deposit waste to landfills. In 2018, the Swedish paper production was 10.1 million metric tons, of which 9.2 million tons were exported.
