HCSD SYSTEM FOR ASH DISPOSAL PDF

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.

The second day was packed with lectures of Dr. News from process industries from all over the world. The type of flow relevant for fly ash and the main considerations in the design of such silos were also touched upon. The three day course was relevant to both designers and users of the coal handling plants and pipeline transportation and storage of bulk materials. New Delhi, India — Handling of coal and fly ash are a major challenge to sytem engineers in the thermal power plants.

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. Greg Page, retired chairman and chief executive bcsd of Cargill will serve as non-executive chairman of the board of Corteva Agriscience.

Ash slurry transportation pipes from slurry pumps upto ash dyke including garlanding of the dyke. The most visposal method of disposing ash in such cases is by pumping it in form of slurry through cast basalt pipes. The topics addressed were coal handling, pneumatic conveying, high concentration slurry disposal and silo design.

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.

De-blocking facility is also considered either by the HCSD pump itself or through a separate water pump. The high pressures result in higher power consumption though the water requirement is lower in this system.

Scientific Image of the Day: Valves at suction and discharge of ash slurry transportation pumps. Subscribe to the newsletter.

Indian Institute of Technology. Demech has a proven track record of flr execution of such systems. Fettig will become non-executive chairman of Dow. Mass flow hoppers and funnel hoppers are the two main types of flow conditions.

Ash Slurry Disposal System

These pumps have mechanism for capacity variation depending on the characteristics of the slurry. Home Ash Slurry Disposal System.

A single intelligent solution for completely networking sensor-based measuring systems makes it possible. The day concluded with Dr. 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 the system design.

Ash Disposal Systems

There were various sessions 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 into useful product is not always possible.

Lower operating power consumption. Our portfolio can be seen here. Proper monitoring of the slurry properties is the key to success of the system. Pumping at higher concentration, hence low water consumption. News on the topic Dispksal and MG2: In spite of double pumping in low concentration slurry pumping, the power requirement is either low or equal.

Ash spreads in layers enabling vertical filling, hence land requirement is reduced.

High Concentration Slurry Disposal Accepted at Power Plants

Literally systme water releases out, hence no need for water retaining walls or recovery system in pond area. Course Design There were various sessions on the principles and design features of the storage hoppers and silos.
