The economic income effect, capital and labor substitution effect for energy consumption are analyzed in the paper by using panel data including 29 provinces in China from 1985 to 2007. Empirical analysis indicates that: (1) fixed effect model is relatively appropriate among mixed regression model, fixed effect model and random effect model. (2) influence of economic income on energy consumption is...
There are two configuration modes of the FGD booster fan in thermal power plants. One is to install booster fan behind induced draft fan, called the separation mode; the other is to integrate the two kinds of fans, that is to cut off booster fan, but install a bigger induced draft fan which can support the pressure head for the whole system, called the integration mode. Through detailed analysis,...
The design is bio-fuel raw material drying equipment which is cross-flow belt dryer based on high-temperature hot water as the medium. According to the drying experiments, obtained the drying curve of materials at different temperatures. Through the experimental data, the general parameters of dryer were determined. The features of this design is that heat from the high-temperature hot which comes...
This paper presents a steady-state simulation study of oxy-fuel gas cycle power plant with CO2 amine absorption process using process software Aspen HYSYS™. The oxy-fuel gas cycle power plant studied was decomposed to four units: the air separation unit (ASU), the gas turbine cycle, the heat recovery steam generator (HRSG) and the CO2 capture process. Based on the steady-state simulations, the energy...
Natural gas consumption growth rate in Iran over the past decade has been usually over than the world wide consumption. As temperature variation has an inevitable effect on raw material consumption which supplies thermal and cooling energies in different areas of the society so in this research we are going to investigate the temperature effects on different sectors of natural gas consumption such...
With China's rapid economic development and the world's total primary Energy declining, Energy bottleneck effect on China's economy has become increasing evident. China's economic growth pattern is in the transitional period from extensiveness to intensiveness, the improvement of the energy structure also becomes more urgent. In this paper, the authors put forward some measures to adjust China's energy...
According to the basic law of energy conservation and conversion, the energy consumption evaluation indexes of two basic research objects in oil-gas gathering and transferring system, i.e. stations and pipelines, are established. On the basis of that, the energy consumption evaluation indexes for the whole system are obtained through mean weighted method. Then heat loss rate and pressure loss rate...
The problems such as the easily frosting of the evaporator and the poor system performance in low outdoor temperature can be effectively solved with the solar-air dual-source heat pump technology. In this paper, based on the previous working of the research group, the steady distributed parameter method has been adopted to establish the mathematical model of a new solar-air dual-source heat pump system...
The Combined cooling, heating and power (CCHP) system should be operated under the optimal scheme to meet the varying demand for cooling, heating and electricity and to reduce cost and save energy for buildings. Based on the analysis of the energy flow, a mixed integer linear program (MILP) optimal model has been developed. The objectives are to minimize the annual total cost, primary energy consumption...
In order to study the removal effect of non-thermal plasma (NTP) after-treatment system on diesel engine harmful emissions, a dielectric barrier discharge (DBD) plasma reactor is designed, and the NOx removal effect is studied. The results show that reduce the initial concentration of NO, increase the residual time and decrease the gas flow rate would get a high NO removal efficiency. NO reduction...
China will more firmly embrace green and low-carbon development ideals and step up efforts in saving resources and protecting the ecological environment. Therefore, the green taxation policy is just part of a portfolio of possible policy changes. Under this background, this article summarizes many countries' green taxation policy, and explains the objective of polluter pays principle and the mechanism...
According to China's eight major economic regions of inland areas, This paper conducts a decomposition research of China's regional energy intensity between 1997 and 2007, from the perspective of regional differences with AVD1 decomposition method, points out that China's energy intensity maintains a downward trend, decline of 28.42% between 1997 and 2007, of which the regional efficiency factor is...
In literature, variable speed control of belt conveyors is recommended to save energy consumption. However, the current implementations mostly focus on lower level control loops without operational considerations at the system level. This paper intends to take a model based optimization approach to improve the operation efficiency of belt conveyors with consideration of various constraints. Specifically,...
Based on the theoretical principles of Kuznets hypothesis, this paper firstly proposes the Kuznets hypothesis of energy consumption. Empirical analysis in China's 29 provincial regions shows that: The current situations of China's provincial regions have not met the inverted U-shaped curve's inflection of the energy Kuznets hypothesis yet. According to the relationship between Energy consumption and...
There are some basic issues and preconditions easy to be neglected which will affect the establishment of energy stratagem when analyzing the energy situation. The first is overrating the potentials of energy saving and energy consumption reducing. The second is the limited recognitions of the environment carrying capacity. The third is ignoring the huge demand for the fossil energy in the countryside...
Temperature and pressure are important parameters related to energy consumption and safe operation of oil depot. A mathematical model is established from the point of temperature drop and pressure drop during storage and transportation process based on the reasonably simplified physical model of oil depot. Then parameter distributions of each node are obtained by the application of sequential modular...
In order to explore the energy saving space on campus, it is an effective way to establish an electricity sub-metering system on campus. The background and the purpose of energy sub-metering on campus, and a total electricity sub-metering solution based on a detailed energy consumption analysis of the laboratory building are introduced. With the implementation of this solution, the real-time laboratory...
Along with the rising energy consumption in the world, new technologies will influence the way we generate, distribute and consume energy. Alongside others, distributed energy generation becomes a major trend in many countries. The fast upward penetration of Distributed Energy Resources (DER) and the ongoing trend towards a more competitive electricity market requires new technologies and policies...
In this paper a type of ultra supercritical boiler was researched for BMCR operating condition numerical simulation with the CFD software Fluent. When this type of boiler burning design coal in the BMCR operating condition, the combustibles content of fly ash is low, the combustion efficiency is high and the emission of NOx is low. The maximum heat load of the wall is located between the burner and...
This paper empirically analyzes the effect of import trade spillover on the industrial energy consumption intensity, based on a panel of 32 industrial sectors for 1998-2007.The results show that research and development spillovers embodied in imports have indeed contributed to a decrease of industrial energy intensity both in high and low energy consumption intensity group in China. This paper will...
