What is the biogas system?
The biogas system is a technology that produces biogas. Biogas is a type of renewable energy created by anaerobic digestion of organic matter. Anaerobic digestion concerns the decomposition of bacteria, which occurs in an environment without oxygen. Fuel can be used for heating or in its concentrated form for vehicle drive. The biogas system provides an airtight environment for anaerobic digestion and usually consists of a digestor and gas holder.
Digester is an airtight tank in which organic waste is fired and unfolded. Organic materials usually include waste for animals, vegetable waste and energy crops or crops that are grown for the explicit purpose of fuel production. The bacteria in the digestor tank decompose waste and, as decomposed, is released by gases such as carbon monoxide, methane, hydrogen and nitrogen. By means of the pressure system, the gases are released in the digestor into the hole in the gas holder. The holder is specially designed to allow gas to flow freelyinto the holder and prevented any gas used to escape back to the digestor 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. Once the gas is used, it can then be used as a fuel.
To improve the efficiency of the biogas system, the porridge in the digestor should be maintained with a slightly basic pH. Digester should also be maintained at 29-41 degrees Celsius (84.2-105.8 degrees Fahrenheit) to ensure rapid decomposition with optimal gas production. The porridge should occasionally be mixed to prevent the formation of the hard cortex on the top of the waste, blocking the gas from traveling towards the holder.
operating procedures may vary depending on the design of the biogas system. The above -ground biogas plant is easier to maintain and benefit from solar heating but in buildingsNicness requires more care. The biogas system underground is cheaper to construct and feed more easily, but more difficult to maintain. Feeding or adding organic materials to the digestor will vary depending on the design. The biogas system of batch feed decomposes mainly solid waste, which is added to the tank in installments, while the models of continuous feed constantly bring mostly liquid waste to the digester.
Biogas is often preferred to fossil fuels such as coal or oil because it is renewable, costs less, use otherwise unnecessary materials and have lower carbon power. Carbon is an important part of a healthy atmosphere in small quantities, but is problematic when too much is emitted. The carbon contained in fossil fuels was buried for such a long time of ancient organic matter, which is no longer part of the carbon cycle. When released by combustion of fossil fuels, it increases the concentration of carbon. However, biogas come from living or recently dead orgaNisms whose carbon content is still in the cycle, so the burning of these fuels disrupts less to disrupt the concentration of carbon in the atmosphere.
