城市生活垃圾能源的利用 总被引:4,自引:1,他引:3
随着工业生产的发展和人民生活水平的提高,工业废弃物和生活垃圾量急剧增多.同时.垃圾成份也逐渐变化;一方面因为民用能源逐渐以煤制气、液化石油气和电能为主、民用燃煤减少,使得灰渣量大大减少;另一方面轻工业生产所废弃的纸、布、塑料、橡胶、木料等大量增多.垃圾堆放不仅侵占土地,污染环境,而且造成可燃物流失.如按我国城市垃圾年 相似文献

据调查,城市居民每人每天产垃圾约1公斤。城市生活垃圾中含有重金属:汞、镉、铅、砷、铬等元素的多种化合物,苯、酚等有害有机物,以及医院丢弃的有毒药用品和细菌、传染病菌、病人污染物,这些垃圾会污染环境。随着世界城市化进程的加快,城市生活垃圾处理成了世界各... 相似文献

O Nam–Chol Pak Hyo–Song Sin Yong–Chol Ri Yong–Hyok Kim Yong–Nam 《Energy Sources, Part A: Recovery, Utilization, and Environmental Effects》2018,40(24):2914-2922
Municipal Solid Waste (MSW) is being used in energy-to-waste plants and as fuel substitutes in different industrial processes. Particularly Refuse Derived Fuel (RDF) from MSW has been widely using in the current practice. This paper aims at conducting a feasibility study of energy recovery of RDF from MSW generated in Pyongyang per year. This study considers the combustibles as RDF resource (i.e. plastics, paper, textile, mixed organic waste, wood, and rubber) in an evaluation of energy recovery. This feasibility study is conducted in two ways: the evaluations of potential energy content and electricity from the RDF resource, which are carried out by methodologies based on heating values of RDF resource and efficiencies of energy recovery, respectively. The results show that the total energy content from RDF resource based on Lower Heating Value (LHV) is approximately 2,813,678.7 GJ/yr, while it is available to generate electricity in a range of 101,320,570?210,435,030 kWh/yr depending on different net efficiencies. This research findings provide a feasibility of RDF utilization for energy recovery to the local planners. 相似文献

Exergy analysis of renewable energy sources 总被引:2,自引:0,他引:2
Oil crises in the past years made more obvious the dependency of economies on fossil fuels. As a consequence, the need for new energy sources became more urgent. Renewable energy sources could provide a solution to the problem, as they are inexhaustible and have less adverse impacts on the environment than fossil fuels. Yet, renewable energy sources technology has not reached a high standard at which it can be considered competitive to fossil fuels. The present study deals with the exergy analysis of solar energy, wind power and geothermal energy. That is, the actual use of energy from the existing available energy is discussed. In addition, renewable energy sources are compared with the non-renewable energy sources on the basis of efficiency. 相似文献

This paper analyzes the role of renewable energy sources (RES) in the Mexican electricity sector in the context of the proposed renewable energy bill currently under consideration in the Mexican Congress. This paper was divided into three parts. The first part presents a chronology of institutional background related to the RES. This is followed by an analysis of the coordination and management system of the Mexican electricity sector, which can facilitate the promotion and integration of the RES without significant structural changes. Finally, the pros and cons of the renewable energy bill are analyzed in order to demonstrate the need for greater coherence between the bill and the coordination system of the sector. It is concluded that when inconsistency is eliminated, RES would strongly be promoted in Mexico. 相似文献
