Dry Solids Pump Coal Feed Technology Program
Performer: Aerojet Rocketdyne
Project No: FE0012062
Program Background and Project Benefits
This project will develope a high-pressure dry feed pump for gasification processes to enable feeding of low-rank coal by constructing, operating, and testing a pre-commercial-scale prototype (600 tons per day at a pressure gradient of 1,000 psi). Novel dry feed technologies have the potential to significantly improve the efficiency of gasification in two ways; enabling slurry-fed gasifiers to run effectively on low rank coal, and enabling dry-fed gasifiers to run at high pressure. This would increase the efficiency of the gasifier and reduce plant capital, maintenance, and operating costs, resulting in less than half the life-cycle cost (capital and operating combined) of the state-of-the-art dry solids lock hopper feed system, and is also expected to perform with at least twice the mechanical efficiency of conventional feed systems.
