Research On Dynamics Of Waste Heat Recovery Power Generation Process

Rece(?)rs, with the rapid economic development of China, energy issues attracted (?)read attention of people. In order to solve the energy issues effectively, the state (?)ted the guidelines of development and energy conservation both. China is (?) in waste-heat resource and has great potential in energy saving. So effective;.(?) waste heat is an important issue for energy conservation and has important (?)cal significance for our country to solve the energy issues. This paper will focus (?)he organic Rankine cycle in waste heat recovery power generation process.First,(?) on a lot of research work, this paper made an basic structures and basic prin (?) of the was(?)heat recovery power generation organic Rankine cycle, the adva(?) of the (?)anic Rankine cycle compared to the conventional water-steam Rankine cycle in waste-heat recovery power generation and the application (?)ground.Work(?)rocess of the evaporator is that the organic working fluid in the tube absorb hea(?) and working fluid changes form unsaturated liquid to saturated liquid, unsaturate(?),saturated (?), superheated gas. So the evaporator can be divided into three regi(?)ooling region, two-phase region, superheated region. Each evaporator heating su (?)can be see(?) as a heat exchanger, and as a fundamental part of the model, th(?)evaporator is composed of three series heat exchangers. The transfer function (?) of single-phas region and two-phase region are established respectivel(?) then a complete model of the evaporator model is formed and the dynamics (?)porator are analyzed.Final(?)ording of the high-order and more complex features of the waste-heat generation (?)covery process model, and different model order methods are applied to reduce th(?)del order. Simulation results show the effectiveness of the low-order systems.
