Fujian Building Materials Co., Ltd. uses marble powder as a desulfurizer, and uses more than 900,000 tons of marble powder annually.
New use of marble powder, can be used as a desulfurizer
Recently, Fujian Province Building Materials Import and Export Corporation has made new breakthroughs in scientific research, using marble powder instead of limestone powder as a desulfurizer test. The research and development is the first in China, and it has pioneered the use of waste marble powder as a desulfurizer for power plants. This research and development has been promoted, and the annual use of marble powder of more than 900,000 tons can save the company more than 20% of the cost.
The marble powder waste discharged from stone production will cause a lot of land compaction and water quality deterioration. In 2012, the company's leading team conducted several on-site reconnaissance, investigation, sampling and testing on the Nan'an stone powder concentration area, and found that its indicators are consistent with limestone powder. Even better than the indicators of limestone powder. The company immediately set up a stone powder research and development working group, and arranged for the research and development team members to conduct in-depth research, and after many experiments, carefully prepared "marble powder instead of limestone powder as a desulfurizer industrial test program." With the active cooperation of Hongshan Thermal Power Plant, the R&D team members completed a 10%~100% marble powder replacement test after a week of thorough industrial testing. The Fujian Provincial Environmental Monitoring Center maintained two days of on-site monitoring. qualified.
