disposal system and ash utilization shall fulfill the requirement of plant and . the recent revolution in the area in wet disposal is HCSD with reduced water. In such conditions ash is required to be dumped in ash pond / ash pits which are usually far away from the plant area. The most efficient method of disposing ash. The High Concentration Slurry Disposal (HCSD) System is designed to cater the requirement of Fly Ash disposal of Unit 7 to 10 of CPP. This system reduces ash.

Subscribe to the newsletter. An efficient coal unloading system is the key to the movement of coal rake for optimum utilisation.
News from process industries from all over the world. Our portfolio can be seen here.
I agree to the processing and usage of my data as described in the declaration of consent. A single intelligent solution for completely networking sensor-based measuring systems makes it possible. Indian Institute of Technology. Proper monitoring of the slurry properties is the key to success of the system.
The ash slurry disposal takes place based on a sloped disposal concept thereby spreading over a substantial area and solidifies, leaving hardly any ash to fly off. Reduced leaches at the ash disposal area. The company is involved in execution of turnkey projects for coal and ash handling in thermal power plants and has commissioned a large number of successful projects in the last 25 years.
News on the topic Mitaca and MG2: Ash slurry sump with intake valves, ACI liners, jetting nozzles, etc. The type of flow relevant for fly ash and the main considerations in the design of such silos were also touched upon. This article is protected by copyright. These pumps can develop very high pressures but are very costly and have a very high maintenance cost.
Valves at suction and discharge of ash slurry transportation pumps. Home Ash Slurry Disposal System. Another advantage of this systems is the easy maintenance and less cost of spares, that makes the system more viable. In spite of double pumping in low concentration slurry pumping, the power requirement is either low or equal. The second day was packed with lectures of Dr. Speaking on the benefits of the seminar Dr.
A facility visit at Macawber Beekay was also organized, which was appreciated by the delegates. Overview The ash produced in big boilers is so high in quantity, that to utilize it completely converting into useful product is not always possible.
De-blocking facility is also considered either by cisposal HCSD pump itself or through a separate water pump. The day concluded with Dr. The ash produced in big boilers is so high in quantity, that to utilize it completely converting into useful product is not always possible. Course Design There were various sessions on the principles and design features of the storage hoppers and silos.
However, it is important to understand the influence of different materials, grades of the same material on ror handling and conveying performance of the materials and eventually on the system design. However, these two parameters in turn depend on many other conditions like rate of ash to be disposed, pipeline distance, pipeline profile, density of slurry, viscosity of slurry etc.
Demech is the only manufacturer of Cast Basalt pipes in India which are the best option for such highly abrasive ash slurry pumping. New Delhi, India — Handling of coal and fly ash are a major challenge to the engineers in the thermal power plants. Infos can be found under www. Belt conveyors and pneumatic conveying systems are an integral part of the power plant for handling of coal and ash.
Lower velocity, hence longer life for pipe line.
Funds advised by Permira, an international investment company, acquired the site at a price in the high double-digit million dollar range. Scientific Image of the Day: Technical Details Flow quantity of Slurry and pressure required are the basic parameters required for designing the system. The carrying medium is always water. Fettig will become non-executive chairman of Dow. These pumps have mechanism for capacity variation depending on the characteristics of the slurry.
The viscosity of slurry does not have much effect for such conditions while calculating pressure requirement, but as the slurry concentration increases the viscosity effect has a dominant effect for calculating pressure requirement.
Such high pressures can be developed using piston diaphragm pumps. The high pressures result in higher power consumption though the water requirement is lower in this system.

Commenting on the frequency of the course, Dr. The third day started with Dr.
