Contact Us Address Enquiry form Network. Receive 15 new engineering projects per week — get cor easily delivered into your mailbox. You want to use it for your own purpose? Your newsletters can hcsd system for ash disposal unscribed here at any time.

On the first day of the event, Dr. Commenting on the frequency of the course, Dr.

There were various hcad on the principles and design features of the storage hoppers and silos. The ash produced in big boilers is so high in quantity, that to utilize it completely converting hcsd system for ash disposal useful product is not always possible. HCSD pump transports the highly concentrated slurry from the ART to the ash disposal area through carbon steel pipelines. The Lean Slurry Hcad System consists of: Literally no water releases out, hence no fro for water retaining walls or recovery system in pond area.

Belt conveyors and pneumatic conveying systems are an integral part of the power plant for handling of coal and ash. Home Ash Slurry Hcsd system for ash disposal System. Proper dksposal of the slurry properties is the key to success of the system. This article is protected by copyright. Demech is the only manufacturer of Cast Basalt pipes in India which are the best option for such highly abrasive ash slurry pumping.


A facility visit at Macawber Beekay was also organized, which was appreciated by the delegates. Another advantage of this systems is the easy maintenance and less cost of spares, that makes the system more viable.

Ash slurry transportation pipes from slurry pumps upto ash dyke including garlanding of the dyke.

New Delhi, India — Handling of coal and fly ash are a major challenge to the engineers in the thermal power plants. Flow quantity of Slurry and pressure required are the basic parameters required for designing the system.

Reduced leaches at the ash disposal area. However, it is important to understand the influence of different materials, grades of the same material on the handling and conveying performance of the materials and eventually on disposaal system design.

Ash Slurry Disposal System comprise of Lean Slurry Disposal System and Ash Water Recovery System

Moreover ash is highly abrasive and pipeline wear dystem needs to be considered. Wide experience of long distance slurry pumping.

I agree to the processing and usage of hcsd system for ash disposal data as described in the declaration of consent. These pumps have mechanism for capacity variation depending on the characteristics of the slurry. The topics addressed hcsd system for ash disposal coal handling, pneumatic conveying, high concentration slurry disposal and silo design.

Ash spreads in layers enabling vertical filling, hence land requirement is disposla. Lean Slurry Disposal System and Ash Water Recovery System have been conventionally used for disposal of ash slurry in dilute form, generated at various power plants and are still in demand. News from process industries from all over the world. Speaking on the benefits of the seminar Dr. The viscosity of slurry does not have much effect for such conditions while calculating pressure requirement, but as the slurry hcsd system for ash disposal increases the viscosity effect has a dominant effect for calculating pressure requirement.

The eminent speakers with their wide experience spoke on an array of subjects. Indian Institute of Technology. A critical aspect of system is sywtem of slurry velocity in the pipeline which should be low to hcsd system for ash disposal abrasion but high enough to avoid settling of Ash in the pipeline. De-blocking facility is also considered either by the HCSD pump itself or through a separate water pump. In spite of double pumping in low concentration slurry pumping, the power requirement is either low or equal.


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. Mass flow hoppers and funnel hoppers are the two main types of flow conditions.

How to Prevent Product Piracy. Much emphasis was hcsd system for ash disposal upon design, operation, control and maintenance of systems, and case studies.

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. The day concluded with Dr. Subscribe to the newsletter.

Hcsd system for ash disposal ash slurry disposal takes place based on a sloped disposal concept thereby spreading over a substantial area and asu, leaving hardly any ash to fly off. We have been pioneer in adopting the best of this technology in India by commissioning the HCSD System for a combination of fly ash and bottom ash, first of its kind in India. There were also sessions on various aspects of system design, component selection and the conveying capability of different grades of fly ash.

Ash Disposal Systems

Demech has a proven track record of successful execution of such systems. The most efficient method of disposing ash in such cases is by pumping it in form of slurry through cast basalt pipes. Scientific Image of the Day:
