Analysis of related technologies of biogas power generation

my country has a history of using biogas to generate electricity for more than 30 years, but the domestic biogas power generation research and application market is still in an incomplete stage. Biogas power generation has received widespread attention and active promotion in some developed countries. The use of biomass energy to generate power grids accounts for about 10% of the total energy in Western Europe.

Biogas combustion power generation It uses biogas generated by anaerobic fermentation treatment to be used on the engine and is equipped with a comprehensive power generation device to facilitate the generation of electrical and thermal energy. Using biogas to generate power has the characteristics of innovating efficiency and saving energy, and is a widely distributed and inexpensive distributed energy source. We should know what are the related technologies for biogas power generation? Let’s analyze it for everyone below.

1. Biogas fermentation.

Biogas fermentation is defined as: biogas fermentation, also known as anaerobic fermentation or anaerobic digestion. It refers to the process of organic matter (such as crop straw, weeds, human and animal feces, garbage, sludge, urban domestic sewage and industrial organic wastewater, etc.) under anaerobic conditions, and finally produce biogas through the catalysis and metabolism of various microorganisms of various types, huge quantities and different functions.

2. Biogas power generation

Biogas power generation technology is a new technology for comprehensive energy utilization that integrates energy conservation. It uses a large amount of organic waste in industry, agriculture or urban life (such as wine lees, poultry and livestock manure, urban waste and sewage, etc.) to generate biogas produced by anaerobic fermentation, driving the biogas generator set to generate power, and can fully utilize the waste heat of the generator set for biogas production.

The thermal efficiency of biogas power generation cogeneration projects varies greatly depending on the power generation equipment. For example, if a gas internal combustion engine is used, its thermal efficiency is between 70% and 75%, while if a gas turbine and waste heat boiler are used, the thermal efficiency can reach more than 90% under re-burning.

Biogas power generation technology itself provides clean energy, which not only solves the environmental problems in biogas engineering, consumes a large amount of waste, protects the environment, and reduces greenhouse gas emissions, but also turns waste into treasure, generating a large amount of heat and electricity, and also brings huge economic benefits.

It can be seen that we can use the biogas power generation technology in some rural remote areas and many places with severe power shortage, such as pastoral areas, islands, remote mountainous areas, and other places where high-voltage power transmission is more difficult, but these areas have rich biomass raw materials. If small biogas generator power stations can be developed according to local conditions, they can use their strengths and weaknesses to supply power on site.
