The Optimization Sesearch About Storage Technology Of The Biomass Gas Central Supply System

In all of the new energy resources, the biomass energy has the most compatibilitywith the modern industrialization technology and the society life. Exploiting and making use of thebiomass energy can resolve the agriculture waste, reduce environmental pollution, and improve theecology environment. Also it has the immeasurable effect to resolve the present energy structureillogical situation, reduce the national economy risk caused by the energy crisis. So it has become afocus regarded by the energy sources circles.It is more different to transform using the biomass energy conversion for every country. Indeveloped country, it is mainly used in the large scale industries such as energy production, centralheating supply etc. Also used in rural living fuel and the biomass gas central supply have come intothe moment of testing and applying.In this topic, the optimization research about the gas storage technology is done aiming at thebiomass gas characteristics and central supply rural living gas characteristics.By the research we find that the physical and chemical characteristics and fire performance of thebiomass gas have great relation to the gas storage technology, and they affect selecting the gasstorage facilities; the gas load and its changing rule are the main factors for selecting the gas storagetechnology plans, especially they have greater effect on the gas storage pressure and scale; thepipeline flow characteristic determines the gas storage parameters; the investment of the gas storagesystem takes bigger proportion of the project's whole investment, which has great significance tooptimize the storage technology plan.The innovation points of this paper are as follows:(1) In unheating areas, the wet gas tank with lowpressure is set more economical and reasonable than the dry one.(2) When the gas storage amount is less, the gas tank can be not set.(3) The overground fixed-capacity gas tank can carry out the automatic constant pressure gas supply, so it is valuable to popularize.(4) In the areas with good soil geological conditions, the underground gas storage technology is feasible to adopt.(5) It is suggested to take the study of remove the CO₂ and N₂ in the biomass gas to improve thescience and technology content, fuel gas quality and the whole economic benefit of the item in thebiomass gasification system.
