It is of great significance to actively explore the digitization budget management and empower intelligence expressways in response requirements needs national reform expressway intelligence. This paper adopts case study method, selects typical enterpr
A fault protection method is proposed for flexible direct-current (DC) power systems based on the cosine similarity of currents in current-limiting reactors. The typical characteristics external and internal faults a DC system were analyzed. principles current reactors used to distinguish between faults. ratio average positive negative voltages reactor was then types line. Finally, simulation model circular constructed using MATLAB/Simulink software (2018b). results show that scheme can...
For comprehensive research on the dynamics of U-tube natural circulation evaporator in plant, modular and lumped parameters method is used to establish mathematical model steam generator. Steam generator divided into three parts model: primary water side, metal side secondary side. Secondary includes five modules. Then, dynamic simulation experiment can be made basis model. The results consistent with actual data adaptability rationality are verified.
Rotary air preheater is adopted widely in large power plant boiler,due to poor working conditions, inside rotary preheater,plugging ash and corrosion happens easily,causes the rise of exhaust gas temperature,fan resistance increases,causes serious damage safe economic operation plants,so heat transfer flow remains be further optimized.By studying characteristics preheater, simplifies rotational structure a cuboid wind tunnel,internal layouts more groups components,through periodic switching...
Solid state switching semiconductors like MOSFETs can realize high repetitive voltage pulse output with a wide adjustable pulsewidth range, which are of interest in laser technology and application, X-ray tomography, ion implantation, etc. In this article, an isolated drive method was proposed to driving series range applications, while omitting the need for power supplies. proposed, charging discharging path input capacitance main set respectively, narrow ON/OFF signals utilized. Its...
The compression of the flue gas is one most critical processes CO2 recycling in oxy-fuel combustion technology. With a 300 MW Oxy-fuel pulverized coal fired boiler taken as an example study, selection compressors its compressing system analyzed by thermodynamic calculation. In this paper, two centrifugal with same specification are parallel running Scheme 1 selection, while axial compressor and piston series operation 2 selection. It shows that has advantage energy consumption water...
If the ventilation condition in underground cable tunnel of substation is not good, due to heat emitted from long running cable, temperature could be raised, and carrying capacity reduced, sometimes resulting combustion with considerable economic loss. When a fire occurs tunnel, only takes away generated by burning cables but also increases oxygen content which has positive negative effects on spread fire. Therefore, selection proper conditions great significance suppression tunnel. The...
This paper focused on researching the pulverizing system of a 300MW oxy-fuel coal fired boiler, which took dehydrated recirculation flue gas as drying medium. According to working principle, established simulation model, and completed dynamic tests basing IMMS platform. The included disturbances pressure inlet opening degree main valve. results demonstrate that model is precise, stable it possesses good characteristic.
SO X emission control of the marine exhaust gas can be achieved by post-processing desulfurization and LNG’s usage. The two solutions are discussed technical economic analysis. Four kinds have differences on system composition, wastewater discharge, applicable waters, absorbents so on. pay-off periods ranged from 0.5 to 2.2 years, which depended ship type’s difference. is about one year, but some hidden costs for LNG ship’s promotion difficult estimate.
With the conceptual design 300MW oxy-combustion of pulverized coal boiler for study, according to its working principle, we divide whole into several subsystems, and complete dynamic static simulation model based on IMMS platform. The results show that, established is stable, trend characteristics reasonable, error within permissible range, which provides a reference as whole.
It presents the compressor gas-cooler of a 300 MW Oxy-fuel pulverized coal fired boiler and established simulation model cooler by mechanism analysis method. On platform, heat transfer performance dehydration properties are studied on different pressure conditions. The simulated experiments show that when flue gas inlet is greater than design pressure, with increase exchange will declines; water separation amount increases initially then decreases subsequently.
Based on a 300MW Oxy-fuel pulverized coal boiler,this paper established dynamic mathematical model of air separation system distillation column, and compiled simulation procedure with the Fortran language platform IMMS. With column as object research, it carried disturbance experiment about outlet flow purifier extractable volume liquid nitrogen in lower tower. The results demonstrate that when decreases, purity gas is reduced by 0.39%, oxygen 1.5%;when constant increased 0.2%, 0.06%.
An experimental study on the desulfurization system by atomized ammonia injection was conducted in tail flue of a 300MW CFB boiler.
