These pumps have mechanism for capacity variation depending on the characteristics of the slurry. Reduced leaches at the ash disposal area. Technical Details Flow quantity of Slurry and pressure required are the basic parameters required for designing the system.

High Concentration Slurry Disposal Accepted at Power Plants

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. New Delhi, India hcssd Handling of coal and fly ash are a major challenge to the engineers in the thermal power plants.

The ash slurry disposal takes place based on a sloped disposal hcsd system for ash disposal thereby hcsd system for ash disposal over a substantial disposl and solidifies, leaving hardly any ash to fly off. The carrying medium is always water.

Proper monitoring of the slurry properties is the key to success of the system.

High Concentration Slurry Disposal Accepted at Power Plants

HCSD pump transports the highly concentrated slurry from the ART to the ash disposal area through carbon steel pipelines. 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. Scientific Image of the Day: Home Ash Slurry Disposal System. The second day hcsd system for ash disposal packed with lectures of Dr.


The high pressures result in higher power consumption though the water requirement is lower in this disposl. The third day started with Dr.

Wide experience of long distance slurry pumping. 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.

Literally no water releases out, hence no need for water retaining walls or recovery system in pond area. The type of flow relevant for fly ash and the main considerations in the design of such silos were also touched upon. 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.

On the first day of the event, 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.

There were various sessions on the principles and design features of the storage hoppers and silos. However, it is important to understand the influence hcsd system for ash disposal different materials, grades of the same material on the handling and conveying performance of the materials hcsd system for ash disposal eventually on the system design.

In spite of double pumping in low concentration slurry pumping, the power requirement is either low or equal. Demech has a proven track record of successful execution of such systems.


Valves at suction and discharge of ash slurry transportation pumps. Hcsd system for ash disposal quantity of Slurry syatem pressure required are the basic parameters required for designing the system.

Ash slurry sump with intake valves, ACI liners, jetting nozzles, etc. Lower velocity, hence longer life for pipe line. There were also sessions on various aspects of system design, component selection and the conveying capability of different grades of fly ash.

The topics addressed were coal handling, pneumatic conveying, high concentration slurry disposal and silo design. Course Design There dispoal various sessions on the principles and design features of the storage hoppers and silos. Our portfolio can be seen here. The three day course was relevant to both designers and users of the coal handling plants as pipeline transportation hcsd system for ash disposal storage of bulk materials.

Demech is the only manufacturer of Cast Basalt pipes in India which are the best option for such highly abrasive ash slurry pumping. I agree to the processing and usage of my data as described in the declaration of consent. Mass flow hoppers and funnel hcsd system for ash disposal are the two main types of flow conditions. Disoosal emphasis was laid upon design, operation, control and maintenance of systems, and case studies.

Moreover ash is highly abrasive and pipeline wear also needs to be considered.
