Three Key Breakthrough Directions
Breakthrough I: IGCC/cogeneration system and the key technology
Commissioning was completed for the R0110 heavy-duty gas turbine combustion chamber with mid-low calorific values under idle load conditions. Exploratory research has been carried out on a new concept mild combustion model combustor, and the conceptual design for low-pollutant combustor of a natural gas turbine as well as the design and experimental study on a jet nozzle unit have been completed, which established a basis for demonstrating the major special projects.
The facilities for researching key technologies of transport bed gasification have been relocated, upgraded and reconstructed, and the heat testing facility for transport beds is undergoing pressurized heated state commissioning. The following have been commissioned and are undergoing experimental study: gas-solid flow experiment platform for transport bed, experiment platform for continuous high-pressure ash emission and experiment platform for pressurized powdered coal feeding. Technological systems and primary equipment installation for the main pilot plant for the transport bed gasification of 24 tons of coal/day has also been completed.
Breakthrough II: The Circulating Fluidized Bed Combustion Technology
Research and testing on the operation technology and performance of a "600 MWe supercritical circulating fluidized bed boiler" , under "The Eleventh Five- Year" science and technology support plan passed review. The institute has mastered the operating characteristics of supercritical circulating fluidized bed boilers, formed guidelines for unit start-up and debugging techniques, proposed operation schemes for constant and sliding pressure and variable loads for the units, and built up research experience on boilers in practice. In addition, IET completed cold state experimental research on a 660MW supercritical circulating fluid bed boiler, confirmed the advantageous use of the boiler and applied it to the development of supercritical circulating fluidized bed boilers.
Regarding technology for circulating fluidized bed oxygen-enriched combustion, studies on 100kW technology and MW level scaling-up criteria were completed, including technological integration, system scale-up, temperature control and the scaling-up of heat transfer components. The regular operation of a recycling system for 55% oxygen-enriched [concentration] smoke was realized, reaching the predetermined indictors. The research and manufacturing for an MW scale circulating fluidized bed oxygen-enriched combustion pilot plant reached several benchmarks: the plant was designed and is in the construction stage. The input oxygen concentration was 21%-50% as designed, and the oxygen, air and smoke could be mixed to any proportion.
Breakthrough III: The Advanced Light-power Technology
The key technologies of light-duty engine technology have achieved consecutive achievements. The 60 thrust-kilogram turbojet engine researched and manufactured by our institute gained a success in its maiden flight, and the progress of turbofan engine research is continuing smoothly.
Our institute is consistently advancing the “R&D and Verification of the Technology for All \Gas Turbine Models”, an major directing project of the Knowledge Innovative Program of CAS, while also completing the engineering design of the integrated engine.
