热电联产是指发电厂同时生产电、热能的工艺过程,较之分别生产电、热能方式更加节约燃料,是一种高效、清洁、节约能源利用的技术,能产生良好的经济效益和社会效益。由于供热负荷形成受时间差异,地域条件的限制,会设置区域锅炉房供热,满足暂时的生活需求。但是随着社会的发展,大型热电联产机组的投产,区域供热锅炉房必然优先转变为区域供热调峰锅炉房。这种先后关系的差异,极有可能导致多热源联合供热出现不科学,不合理的设计搭配,造成经济效益不能最大化,影响企业经济效益,社会效益,产生能源浪费。本实例就是通过研究呼伦贝尔某供热集团多热源供热联合供热现状,提出改造方案,优化运行的建议,在一定程度上优化热网的水力工况,提升企业效益。 相似文献

A hybrid numerical technique which combines the differential transformation and finite difference approximation is employed to predict the laser heating problem. The energy transfer induced by laser irradiation in the solid is described by Fourier's law of conduction with an energy source modeled by Beer's law. The influences of convective boundary and dimensionless energy absorption at the surface are examined. It is found that at low Biot number, the peak temperature occurs at the surface. As the biot number increases, the location of the peak temperature moves inwards. In addition, the differential transformation results in a concise procedure than other integral transform methods. 相似文献

The quality as well as reliability of electrical energy transmitted to consumers is one of the main parameters of successful operation of the power system. The searching of optimal coefficient's combination of PSS (power system stabilizer) is the main goal of this article. The possibility of application of the new combined approach for the optimal excitation's settings search is presented. MC (Monte Carlo) method, in order to search and select the optimal combination of excitation system, was applied. The proposed method has been researched with a mathematical model of the power system. This model has been built using Matlab/Simulink software. Paper shows advantages and disadvantages of the proposed methods. 相似文献

Abstract The method of energy use effectiveness of oil production and pipe-line transport systems by the efficiency test is suggested. The concept of idealized analogs of the processes for calculation of the minimum necessary energy/work consumption on their realization is used. The idealized analogs, under the assumptions made for their forming, are described. Determining the theoretic energy consumption is based on methods of hydraulic and thermodynamic analysis. 相似文献
