HAT circulation experiment platform based on 600kW minitype gas turbine.The scholars such as the Andrea Lazzaretto of Italy are preceding
The HAT of people is furtherd investigate on the basis of recycling super flowage structure, is used Aspen Plus emulation tool, has been obtained heat exchanger
Optimal location.In China, the research of HAT circulation is started from 1992, and Chinese Academy of Sciences's CAS Institute of Physics first carries out the performance of HAT circulation
Analysis and research, it is believed that HAT circulation can form efficient, height than the novel thermodynamic cycle of function, and high evaluation is made that it.2014
Year, Wei Chenyu is based on HAT circulation split shaft gas turbine test run test and has carried out theoretical research to its overall performance, it is indicated that humidifying
The variation of device outlet humid air water capacity has a significant impact to the ratio function of HAT circulating gas turbine.Zhu Hua is on the basis that HAT is recycled
On propose heat, electricity, cold coproduction the circulatory system, detailed analysis influence of the main controllable parameter of novel system to system performance
And the economic feasibility of system.
Scholars mainly consider to solve compressor for the research of HAT circulation and turbine flow mismatch, circulation are crucial
The research of component humidification machine and the redesign problem of high humidity combustion room.Compared with other thermodynamic cycles, although HAT circulation
Commercialized development and investment risk recycle relevant heat-economy evaluation, the optimization of HAT circulation to HAT there are also to be assessed
And the relevant research such as small-sized HAT circulation is still the research hotspot of current driving force cycle art.
In consideration of it, how to provide a kind of association system, effective and reasonable utilizes solar energy resources and methanol feedstock, and improves
Energy utilization efficiency and generating efficiency are the main problem to be solved at present.
