A Project Of Combined Cooling,Heating And Power Supply In Beijing Analysis And Applied Research

With the rapid development of economy and human excessive demand for resources,human nature is in its own way,a warning to mankind,such as the abnormal climate,water pollution,frequent droughts,floods and fog haze,adversity leads to prosperity,and promotes the use of new energy,environmental protection energy has become a trend.Beijing as the capital,is our country's economic,political and cultural center,need to take the lead in transformation can use mode,realize the harmonious coexistence of human and nature,and need to improve energy efficiency,preferred to choose low carbon energy,gas heating and electrical trigeneration systems belong to the new technology of low carbon environmental protection,has practical significance for the new technology to carry out the research.In this paper,we introduce the key project of ecological development demonstration area located at Beijing huairou area within,to choose low carbon environmental protection way of energy supply is particularly important.Paper first carding the trigeneration systems of natural gas application situation,the natural gas at home and abroad,summarized the trigeneration research hot topic,for the promotion of natural gas at home and abroad and cold heat power trigeneration actual application situation are summarized,analyzed the difference;Second combination of this paper will research object,to overview of project construction,analysis the project of electricity load,heat load and cooling load,and living hot water and steam load function of total demand,to meet the functional requirements above,reached the requirements of ecological demonstration area of low carbon environmental protection,which leads to the cold and hot electricity by using natural gas,the necessity and adaptability of trigeneration Further to the project of cold heat power trigeneration systems by using natural gas power advantage analysis;Secondly for trigeneration project system may adopt two kinds of analysis,the two kinds of schemes of equipment composition,technological process and control system and a series of problems are studied;Finally,comparing the two scheme concluded that project appropriate USES gas trigeneration systems.Trigeneration system can satisfy the requirement of project power by using natural gas,reduce the emissions of greenhouse gases such as carbon dioxide,achieved the requirement of low carbon energy saving.Because large hotel type and energy consumption pattern is similar,hope that through the objective of the study,similar to large hotel building adopts low carbon environmental protection energy,use of natural gas trigeneration system technology to provide the reference and reference.
