Ash Disposal Systems

An efficient coal unloading system is the key to the movement of coal rake for optimum utilisation. Contact Us Address Enquiry form Network. The day concluded with Dr. Infos can be found under www.

Demech has a proven track record of successful execution of such systems. The third day started with Dr. Sysyem from process industries from all over the world.

Technical Details Flow quantity of Slurry and pressure required are the basic parameters required for designing the system.

The eminent speakers with their wide experience spoke on an array of subjects. Slurry flow rate is drastically reduced, hence lower pipeline sizes.

High Concentration Slurry Disposal Accepted at Power Plants

Ash slurry sump with intake valves, ACI liners, jetting nozzles, etc. A critical aspect of system is selection of slurry velocity in the pipeline which should be low to minimize abrasion but high enough to avoid settling of Ash in the pipeline.

The most efficient method of disposing ash in such cases is by pumping it in form of slurry through cast basalt pipes. There were also sessions on various aspects of system design, component selection and the conveying capability of different grades of fly ash. There were various sessions on the principles and design features of the storage hoppers and silos. Mass flow hoppers and funnel hoppers are the two main types of flow conditions.


Such high pressures can be developed using piston diaphragm pumps. The topics hcsd system for ash disposal were coal handling, pneumatic conveying, high concentration slurry disposal and silo design.

However, these two parameters asu hcsd system for ash disposal depend on many other conditions like rate of ash to be disposed, pipeline distance, pipeline profile, density of slurry, viscosity of slurry etc. Ash slurry transportation pipes from slurry pumps upto ash dyke including garlanding of the dyke. Ash Disposal Ash Disposal Systems. News on the syatem Mitaca and MG2: Proper monitoring of the slurry properties is the key to success of the system.

The Lean Slurry Disposal System consists of: 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.

Belt conveyors and pneumatic conveying systems are an integral part of the power plant for hcsd system for ash disposal of coal and ash. The second day was packed with lectures of Dr. Much emphasis was laid upon design, operation, control and maintenance of systems, and case studies. We have been pioneer in adopting the best of this aah in India by commissioning the HCSD System for a combination of fly ash and bottom ash, first of its systemm in India.

High Concentration Slurry Disposal Accepted at Power Plants

tor Subscribe to the newsletter. Reduced leaches at the ash disposal area. Flow quantity of Slurry and pressure required are the basic parameters required for designing the system. Subscribe to hcsd system for ash disposal newsletter Your newsletters can be unscribed here at any time. New Delhi, India — Handling of coal and fly ash are a major challenge to the engineers in the thermal power plants.


Receive tor new engineering projects per week — get them easily delivered into sjstem mailbox. De-blocking facility is also considered either by the HCSD pump itself or through a separate water pump. The three day course was relevant to both designers and users of the coal handling plants and pipeline transportation and storage of bulk hscd.

I agree to the processing and usage of my data as described in the declaration of consent. In spite of double pumping in low concentration slurry pumping, the power requirement is either low or equal. Moreover ash is highly abrasive and pipeline wear also needs to be considered. Lower operating power consumption. Wide experience of long distance slurry pumping.

Our portfolio can be seen here. Click on our picture gallery to find out! Hcsd system for ash disposal, it is important to understand hcsd system for ash disposal influence of different materials, grades of the same material on the handling and conveying performance of the materials and eventually on the system design. The carrying medium is always water.

hcsd system for ash disposal ppt

The ash slurry disposal takes place based didposal a sloped disposal concept thereby spreading over a substantial area and solidifies, leaving hardly any ash to fly off. Home Ash Slurry Disposal System.

Pumping at higher concentration, hence low water consumption. 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.
