The utilization of biomass energy, the utilization of biomass energy

<> utilization of biomass energy mainly includes direct combustion, thermochemical conversion and biochemistry.

There are 3 ways to change.

1. Direct combustion: The direct combustion of biomass will still be the main way of biomass energy utilization in China for a long time in the future. Current retrofit thermal efficiency.

Only about 10% of the traditional wood-burning stove, the promotion of fire-saving stoves with an efficiency of 20% to 30% This kind of energy-saving measures with simple technology, easy to promote and obvious benefits are listed as one of the key tasks of rural new energy construction by the state.

2. Thermochemical conversion: The thermochemical conversion of biomass refers to the technology of vaporization, carbonization, pyrolysis and catalytic liquefaction of biomass to produce gaseous fuels, liquid fuels and chemical substances at certain temperatures and conditions.

3. Biochemical conversion: The biochemical conversion of biomass includes biomass, biogas conversion, biomass and ethanol.

conversions, etc. Biogas conversion is the fermentation of organic matter in an anaerobic environment by microorganisms to produce a methane.

The main component of the flammable gas mixture, i.e. biogas. Ethanol conversion is the fermentation of raw materials such as sugar, starch and cellulose to produce ethanol.

Biomass energy is the energy provided by living plants in nature, and these plants use biomass as a medium to store solar energy, which is a renewable energy source. It has been calculated that the energy stored in biomass is 2 times greater than the total current world energy consumption.

Biomass energy, in a broad sense, is the energy form of solar energy stored in biomass in the form of chemical energy, that is, the energy with biomass as the carrier. It directly or indirectly leads to the photosynthesis of green plants, which can be converted into conventional solid, liquid and gaseous fuels, which is inexhaustible and is a renewable energy source and the only renewable carbon source.

In a narrow and legal sense, biomass energy refers to the energy converted from plants, manure and organic waste in urban and rural areas. According to different categories, biomass suitable for energy utilization can be divided into six categories: forestry residues, agricultural residues, domestic sewage, industrial organic waste residue and waste liquid, urban and rural solid waste, and livestock and poultry manure.

Significance of developing biomass energy:

At present, biomass energy accounts for less than 10% of China's total renewable energy consumption. The current "small industry", if it is properly implemented and in the right direction, will become a "giant" in the field of renewable energy in the future. Every year, if all kinds of urban and rural organic wastes are harmless, reduced and recycled, it will play a huge role in China's environment, energy and food security.

With the continuous growth of the development scale of the biomass energy industry, it will gradually change the production and lifestyle of China's agriculture and rural areas, realize the new format of green, low-carbon, circular and sustainable development of the county economy in the new era, and then promote the realization of China's new urbanization, rural revitalization strategy and carbon neutrality goals as soon as possible.

The main forms of bioenergy are biogas, biohydrogen, biodiesel and fuel ethanol.

1. Biogas is a mixed gas produced by microorganisms fermenting organic matter such as straw and livestock manure, and the main component is combustible methane;

2. Biological hydrogen can be obtained by microbial fermentation, and hydrogen is the cleanest source of energy cracking due to the combustion of water;

3. Biodiesel: It is a liquid fuel obtained by decomposing vegetable oil or other oils by using source-disturbing biological enzymes. It is more environmentally friendly as an alternative to diesel;

4. Fuel ethanol: refers to the alcohol produced during plant fermentation, which can be mixed with gasoline in a certain proportion to make the exhaust gas of the emission target cleaner.
