Discussing Free CaO in CFB Ash and it’s Stability: Research Highlight from Coal Ash Asia 2017


- Beijing, China

Professor Qiao Xiu Chen from East China University of Science and Technology joined the discussion at Coal Ash Asia this past July 21-24 in Beijing, China. Prof Chen presented among industry leaders during the Fly Ash and Coal Gangue Track at the most recent AsianCAA event. The below abstract has been translated from its original submission to our proceedings.

Abstract: Circulating fluidized bed (CFB) boilers discharge 2 to 3 times as much ash per 1 kWh as pulverized coal-fired boilers. Overall, the amount of discarded CFB ash has drastically increased in China. However, there is no bulk utilization due to the different physiochemical properties of coal fly ash (CFA) from pulverized coal-fired boilers. One of the key issues is the amount of CaO left after burning, as CaO has negative effects on the soundness of cement. The national standard requires the maximum free CaO of 1% for F CFA and 4% for C CFA. The amount of lime in CFB ash is usually higher than 5% due to the desulfurization process. The utilization of CFB ash becomes harder when ash contains higher amounts of CaO. Presentation Abstracts

This conference we will show the chemical reaction variations of lime prepared at 800, 850, 900, 950, 1000, 1050, 1150, 1250, 1350°C. The calorimetry, precise measurement of lattice parameter and selected area microdiffraction of TEM were used for evaluation. The results showed that the calcite with a fineness of D100<76μm decomposed by 80% after the treatment at 800 or 850°C for 20 min. Complete decomposition occurred from the treatment at 900°C for 10 min. The maximum amount of CaO was 0.53% after the treatment at 1050°C. The amount of CaO started to be higher than 1% from the treatment at 1150°C and was more than 30% after the treatment at 1350°C for 20 min.

The CFB ash does not show a negative effect on the soundness of cement when the highest combustion temperature in the boiler is lower than 1050°C.

High Value-added Utilization of Coal-Related Solid Wastes

Dr. Li Hui Quan, a researcher at Chongqing University recently presented at the recent Coal Ash Asia conference in Beijing, China from July 21-24, 2017. The following is the fully translated abstract of their research. For more information, or to contact this researcher please contact the team at Asian Coal Ash Association.

Thermal power generation is an important component of Chinese energy. Shanxi and Inner Mongolia are regarded as the most important energy bases of China. Large amounts of coal gangue, fly ash, desulfurization gypsum and waste denitration catalyst emerge during the processes of coal mining and coal to electricity conversions. This causes terrible environmental problems due to the low waste utilization ratio. Many metal elements such as Al, Li and Ga, enrich coal-related solid wastes. Our team proposes a theoretical system of the mild separation of active components, the coordinated control of mineral structure and the step by step extraction of associated elements.

We found key technologies of the mild activation by proton acid and deep desilication of silicon, the extraction of alumina by sub-molten salt, the selective adsorption and separation of rare metals, and the directional conversion of silicon resources. The technical system of utilizing alumina & silicon, the step by step extraction of associated elements and the clean recycling & carrier generation of waste denitration catalyst are established. A 3000 tons / annual experimental production line of Al-Si composite from high-alumina fly ash by deep desilication process has been built. The Al-Si composite can replace 80 Bauxite sinter. The establishment of this technical system should be standard practice for the new recycling economy pattern of energy output; low emissions and material preparation, forming green, intelligent and cyclic factories with high resources and ecology amalgamation.

Sustainability Through CSA Cement

- Malaysia

Sustainability is simply the ability to meet the demands of today without negatively impacting the future. This goal is not easily met, especially in the construction industry. With demands for building materials on the rise in places like Malaysia and Vietnam, companies scramble to provide quality building materials such as concrete, cement, ceramic, etc, while still adhering to ever tightening restrictions on emission and waste disposal. Switching unfriendly environmental practices to a more efficient infrastructure of Building materials manufacturers providing suitable coal ash byproducts from local power station waste is not yet common practice. As legislative reform takes its time, researchers are attacking the problem of reusing industrial waste from all angles.

CSA (Calcium Sulfoaluminate) cement is another approach at reducing energy to produce environmentally friendlier cement.  Calcium Sulfoaluminate requires lower heating temperatures to produce. CSA is composed of a mixture of bauxite, limestone and gypsum and burning these at lower temperatures emits representatively lower amounts of carbon dioxide into the atmosphere. Also, the amount of limestone needed is much less. Limestone is said to be one of the key emitters of carbon dioxide in the sintering process. Using less materials and less energy is not only better for the environment, but more appealing to building materials manufacturers.

Dr. Tom Robl, Associate Director, Environmental & Coal Technologies at University of Kentucky’s Center for Applied Energy Research will be presenting the latest research and discussing CSA cement at the upcoming Coal Ash Asia. To join Tom at this year’s event please register by Clicking Here!
