Research On Architecture And Energy Efficiency Of Distributed Biomass Comband Cold Hot And Power System

With the increasing scarcity of fossil fuels and the environmental pollution of theworldwide, it has become the concern of world that the development of new sources andthe improving of energy efficiency. Distributed energy system is a new kind of energysystem with environmental friendliness, reliability and economy, which implements theenergy ladder use, and improve the energy efficiency of the system effectively. Biomassis a new kind of energy that can be renewable, it can achieve zero emissions of carbondioxide and other pollutants reduction, and which is environmental and is benefit tosocial and economic. Distributed biomass system is a new energy system thatcombined cooling, heating and power(CCHP), which use biomass to drive the gasturbine or internal combustion engine. It’s economy and has high energy conversionefficiency, Biomass CCHP technology will have a very good market prospects andsocial benefits in the future.In this paper, based on a large domestic and foreign literature, taken the distributedbiomass CCHP system architecture and energy efficiency as the starting point, introducedthe energy situation of biomass, the cogeneration of biomass CCHP system and the majorcomponents of the CCHP system, and described several major operating modes in detail.Based on these, build a complete architecture mode of biomass CCHP system inexploratory. Then based on the effective using of energy, analyzed the main evaluationindex of the CCHP system. Taking a rural community as a object of the system,analysised heating and power load characteristics of the system, established amulti-objective optimization mathematical model, and got the Pareto optimal solutionaccording the parallel genetic algorithm. At last, analyzed the efficiency of characteristicsof biomass CCHP system on the basis of system optimization results,mode of operationinfluence the efficiency of the whole system,it can improve the efficiency that usingdifferent strategies based on different load periods, it should consider the loadcharacteristics of the CCHP system, determine the equipment according to theconsuming energy of the system,and we should ensure the load factor above50%.
