Use of Cenosphere in Various Industries

A Cenosphere is a type of hollow microscopic ball that is made up of smooth silica and aluminum and other minor ceramic elements. A Cenosphere is also known as Ceramic sphere. Cenospheres are derived in the coal power plants. It has been used for more than 30 years over the world. It has helped us in improving the qualities of many manufactured products in India. When the coal is burnt in thermal power plants, it produces a fly ash that contains ceramic particles that is made largely of alumina and silica. The particles that are produced in the process of coal burning, produces a part of fly ash. In India, Cenospheres are largely made up of silica, iron and alumina. The size of a Cenosphere ranges from 1 to 500 microns that have an average compressive strength of 3000+ psi. Cenospheres are widely used in a variety of products as fillers in low density concrete. Cenospheres are used in plastic and composite materials that are used for producing bowling balls, surfboards, kayaks, in fire bricks, in floor tiles, in insulating materials and in automotive components. Cenosphere are described as the multifunctional filler that mixes well in binders and resins.

Most of the Cenospheres are scooped up or take out from ash ponds. Ash ponds are the place where the fly ash is carried out when the wet disposal takes place in the thermal power plants. Some of the Cenospheres gets collected by themselves at the thermal power plants. The wet microspheres that are collected in the ash ponds are then dried up then processed to specifications and then it is packed up to meet customer requirements. All the Cenospheres that we see are not similar in nature. In fact, all of them are quite different from each other. The property of Cenospheres depends on the consistency of the coal used and it also depends on the operating parameters of the thermal power plant. If the manufacturer makes two things constant, that is, the consistency of the coal used and the operating parameters of the thermal power plants, then the Cenosphere processed would be quite constant.

Fly Ash Versus Cenosphere

Cenospheres are unique free-flowing particles composed of hollow, hard-shelled, minute spheres. A small portion of the PFA (Pulverized fuel ash) formed from the combustion of coal at the thermal power plant is produced as cenosphere India. It is assumed that only about 1 percent of Cenosphere is produced in fly ash from thermal plants due to their hollow and low-density nature and they float in the lagoons where fly ash is discharged. Cenosphere largely consists of Silica, Iron, and alumina. The size of the particles varies ranging from 1 to 500 microns, having an average compressive strength of 3000+ psi. They are alternatively also referred as hollow spheres, microspheres, microballoons, hollow ceramic microspheres, and glass beads. When the hollow spheres float in the lagoons, they are collected and further isolation is carried by froth floatation and then dried. The final application is carried out in a pneumatic conveying system which is connected to a tribo electric separator. In this separator, the ash is divided into three fractions and the cenosphere particles are then separated from iron and carbon. The end product is then used for a variety of applications.

What is fly ash?

As mentioned above, it is considered that only about 1 percent of cenosphere India is produced in the fly ash during the coal combustion in thermal power plant. When coal is burned at a combustion temperature approximately of about 2800oF, the non-combustible ores occurring naturally from coal combustion forms bottom ash and fly ash. According to the cenosphere suppliers in India, bottom ash is a light-weight aggregate component which tumbles to the boiler bottom for collection; whereas, fly ash is carried off with the flue gases. Fly ash particles are then collected and stored in silos for testing and then utilized in different applications for its beneficial chemical and physical properties.

Fly ash material is used widely for its several beneficial characteristics like it increases strength and durability of the application. Further, fly ash particles are less disposed to chemical attacks such as de-icing salts and soil sulfates and thus, alleviate the negative effect of deleterious aggregates.

Properties and Components of Cenospheres

A cenosphere is a lightweight, hollow sphere made largely of silica and alumina and filled with air, metals, or gas. The Cenospheres are manufactured as a byproduct of coal combustion at thermal power plants. Cenosphere-based compounds were fabricated and categorized for their structural and mechanical properties such as tensile, flexural, impact and vibrant mechanical properties such as storage and loss moduli as a function of temperature. The structural qualities were characterized by Scanning Electron Microscopy (SEM) and Wide-Angle X-ray Diffraction (WAXD) though the thermal characterizations were prepared by conducting Differential Scanning Calorimetric (DSC) and Thermo-Gravimetric Analysis (TGA). The DSC studies revealed that increase in cenosphere content has resulted in a decrease in crystallinity of the composites.

The amount of separation in retrieving the Cenospheres from coal fly ash has been valued for both wet and dry separation processes through applying the terminal velocity concept of particles. The diameter and density of the particle are determined by sieving industrial cenospheres and coal fly as type IV. Depending on the estimation, the dry separation process executed similarly to the wet separation process, with a most favorable Newton’s efficiency of 0.54, just slightly lower than that of the wet separation process of 0.6.

The mortar cubes can be made with a combination of Cenospheres and silica fume as a standby for the cement. The test on mortar cubes shown that cement loses its strength because of the replacement of cenosphere, but the loss can be calm down by adding silica fume to it. The strength decrement decreases by ages, displaying that the strength attainment is reduced by the addition of cenosphere. The microstructure has also been studied to show the disintegrated structure on advanced replacement of cenosphere. It was also noted that the hydration products react with cenospheres and, due to this; decline in the quantity of portlandite was witnessed resulting in strength decrement.
