| Abstract: | In a biogas installation, green power is produced from manure and biomass. Because of the optimization and innovation of the biogas industry and the continuously rising energy prices, it is become very interesting to invest in biogas installations. The generated electricity can be sold to energy companies at attractive tariffs for sustainable electricity. The quantity of electricity generated can be guaranteed, making biogas installations attractive investments. A biogas installation also contributes to environmental protection by using sustainable energy resources. For such biogas installation, the digester of the biogas is considered as the main component of the process. Biogas digesters can be made from steel, concrete, plastics etc. but these materials have a problem of either cost, environmental effect or maintenance problems. In this report a 340m3 manure biogas digester will be designed from a different and renewable material. It is designed from an engineered wood product, plywood, which insures a more sustainable production and relatively lower cost with acceptable maintenance. The type and strength of the plywood required, the method of connection of the plywood plates for the required shape of the digester, the horizontal and vertical supports required will be analyzed in this report. The means of integrating the double membrane biogas digester cover is also applied in the report. The digester will be designed in such a way that it is suitable to install at the field within a short period of time and little man power. It is insured to withstand the maximum snow and wind load that could occur for a period of at least 50 years. |
