Between 1967 & 1983

• DCPL provided ash handling technology through in-house R&D and development since mid- 60s.

• Ramagundam Thermal Power Plant, B-Station owned by APSEB is the first plant that was designed, manufactured indigenously and supplied, installed and commissioned in 1971 using DCPL Technology and by deploying Indian resources.

• DCPL provided total design and engineering for entire Ash Handling Plant including equipment design and manufacturing drawings. It rendered services for procurement of standard equipments and supervision of erection/installation of the entire plant.

• DCPL was granted 40 patents on Ash Handling system & equipment during this period.

• Over 50 plants were commissioned using DCPL technology and services such as complete design, engineering, procurement and supervision of erection-commissioning work by DCPL.

• DCIPS emerged as a turnkey contractor in 1983. It is fully equipped with -
– Complete design engineering capability.
– Modern and dedicated manufacturing facility.
– Competent resources for construction and installation services.

• DCIPS Inherited the entire in-house know-how from parent company DCPL. Technological know-how, expertise, patent rights and all technical personnel connected with ash handling were transferred to DCIPS.

• DCIPS has offered following systems to various clients inherited and developed in-house :

1. Bottom Ash : Water Impounded Hopper with Jet pumping, Scraper Conveyor, Submerged Belt Conveyor.
2. Fly Ash Wet Sluicing : Flushing Apparatus, Feeder Ejector.
3. Fly Ash Vacuum Conveying :
a) Dry Disposal.
b) Wet Disposal.
4. Fly Ash Pressure Conveying :
a) Dry storage in Silo.
b) Wet Disposal.
5. Coal Mill Reject handling through Sluicing or belt conveyor system.
6. Silo System with a) Dry Unloading,
b) Semi Dry Unloading, c) Wet Unloading.
7. Ash Slurry Pumping & disposal system.
8. Ash water and seal water pumping system.
9. Instrument air and fluidising air system.
10. Ash water recovery system from ash pond including clariflocculator or plate / tube Settler.

• In 1984, DCIPS entered into a long term technology transfer agreement with United Conveyor Corporation (UCC), USA for transfer of technical know-how of Ash Handling Systems valid upto December 1992.

• In 1990 and then in 1993, DCIPS entered into new agreements with UCC for further upgradation of technology which was valid till July 2000. DCIPS is now free to use all UCC technologies acquired through various technical collaborations with UCC.

• DCIPS acquired latest UCC technical know-how in the following areas :-
- Bottom Ash Jet Pumping Systems.
- Fly Ash Vacuum Conveying Systems.
- Fly Ash Pressure Conveying Systems.
- Silo and Silo Unloading Systems.
- Bottom Ash Dewatering & Storage Bin systems with closed-loop water recirculation ZERO DISCHARGE systems.

• DCIPS have successfully executed over 50 turnkey Ash Plants and presently executing six contracts based on the technology imbibed and upgraded over the years of experience.

• DCIPS always strives for improvement and the quest for excellence has enabled tie up with foreign collaborator for the state of the art technology in slurry disposal. The Sunrise technology of High Concentration slurry Disposal (HCSD) appears to be the ultimate answer to the pollution from the Thermal Power Plants and this eco-friendly technology is determined to change the concept of slurry transportation and storage in near future.
