Architecture and Energy Efficiency of Distributed Biomass based CCHP System based on FCF Method

Abstract

China is a large agricultural country with a huge amount of biomass energy. However, due to the current energy structure, most of the biomass energy in China has not been fully utilized, which not only wastes energy, but also pollutes the environment. The CCHP system is a new type of distributed energy system, so the characteristics of biomass energy are suitable for the energy consumption mode of CCHP system; In this paper, the FCF method(FCFM) is proposed to study and analyze the architecture and energy efficiency(EE) of distributed biomass CCHP system. The working principle of distributed CCHP system and distributed biomass CCHP system are discussed; A FCF optimization objective function model is proposed, and the energy structure and characteristics of biomass cogeneration system are analyzed. A typical rural community is selected as the research object. According to the load data table of the object system, the utilization changes of cooling, heating and electricity loads of the object in a year are analyzed. Biomass cogeneration system converts biomass energy as efficiently as possible through biomass gasification. The whole process realizes the stepped utilization of energy, which has better environmental benefits than conventional cogeneration system.
