What is biogas design?

Biogas design varies depending on the materials and the production scale. Biogas is a type of biofuel consisting of anaerobic or oxygen decomposition of organic materials with bacteria. Organic materials usually include waste for animals and plants and energy crops or crops that are grown for the explicit purpose of fuel production. The gas made from this process can be used for heating purposes or in its concentrated form for vehicle drive. While biogas design differs in details, most biogas plants have similar basic ingredients, including digestor and gas holder. Bacteria in the digestor tank decompose waste and, as decomposed, gases such as carbon monoxide, methane, hydrogen and nitrogen are released. To facilitate rapid decomposition with optimum gas production, the tank is maintained between 29 ° C and 41 ° C (84.2 ° F-105.8 ° F). It is best to keep the porridge in the tank with a slightly basic pH to ensure faster decomposition. When attempting to neutralize the porridge will have the material teeNdence to emit more acidic carbon dioxide, the required decomposition product.

Through the pressure system, the gases are released in the digestor into the hole in the gas holder drum. The design of the gas bracket is specialized to allow the gas to flow freely into the bracket and at the same time prevent any gas from escaping back to the digester or to the external environment. This is important, both for efficiency and safety, because many of these gases are flammable and can cause an explosion when mixed with oxygen or other gases. The porridge in the tank must also occasionally be mixed to prevent hard crust of waste. The bark can capture the porridge gases and prevent the capabilities of the machine to use the gases.

Biogas design

Biogas may vary depending on the amount of gas, the amount of waste at hand and whether the digester is built for batch feeding or continuous feeding. BatchFeeding systems use mainly solid waste, which are added to the tank in installments, and the models of continuous feeding are feeding the liquid continuously to the digester. Biogas design can place the plant either above or underground, although there are advantages and disadvantages for both models. The above -ground biogas plant is easier to maintain and is able to mine from solar heating, but requires more investment in construction because it must be created to handle the internal pressure of the digester. The biogas plant underground is cheaper on the construction and is easier to feed, but it is more difficult to clean and repair.

Biogas is often preferred to fossil fuel energy sources such as oil or coal for both root and economic reasons. The growing carbon concentration in the atmosphere has become a central problem for the problem of global warming. Although both biogas and fossil fuels emit carbon, fossil fuels release carbon, which is buried for many years in ancient biomase and effectively removed from the carbon cycle. ATHlík relaxed during production and use of biogas has been stored in the form of organic matter only recently and is still part of the cycle. Therefore, it does not cause much to upset the carbon concentration in the atmosphere in relaxation.

Biogas production supporters also prefer biogas to fossil fuels because it is a cheap, renewable energy source that uses otherwise waste materials. Biogas Design can provide small pages, making it a viable option for regions in developing countries. Critics of biogas proposal claim that food crops grown for biogas production will create a global lack of food. Biofuels may also cause sodas, water pollution, soil erosion and a negative impact on oil producing nations.
