Energy and environmental issues have become a global focus of attention. With the rapid growth of energy consumption in China, the extensive use of fossil fuels has brought serious environmental pollution and ecological damage. Conventional energy sources such as coal, oil, and natural gas have been extensively exploited and utilized, resulting in a decreasing amount of resources. The widespread use of fuels in China has caused significant waste, and the development of clean renewable energy has become an urgent need for sustainable development.
Renewable energy mainly includes solar energy, hydropower, wind power, geothermal energy, tidal energy, biomass energy, and so on. Among them, biomass energy is one of the earliest energy substances utilized by humans. It is a versatile energy source that can be continuously produced, scaled, stored, and transported on Earth. With abundant resources, wide distribution, and huge development potential, it is an important renewable energy source. The use of biomass gasification technology can achieve zero CO2 emissions, save conventional energy, and meet the requirements of sustainable development.
Biomass gasification refers to the process of compressing or simply crushing biomass raw materials (such as wood chips, sawdust, wheat straw, rice straw, etc.) into shapes, and then sending them into a gasification furnace. Under anaerobic conditions, the high polymers of biomass undergo pyrolysis, oxidation, reduction, and reforming reactions. The tar associated with pyrolysis is further thermally or catalytically cracked into small molecule hydrocarbons, obtaining gases such as CO, H2, and CH4, and thus obtaining combustible gases. This type of gas can be used for various purposes such as heating, warming, hot water, or driving generators. Its emergence is mainly based on the utilization of renewable energy and the pursuit of clean energy utilization; It is an energy application required in the context of energy conservation and carbon reduction.
The reasons are as follows
01. As a zero carbon energy source to combat climate change
Firstly, biomass gasifiers use renewable biomass fuels such as sawdust, discarded crops, food waste, etc. The amount of carbon dioxide released during the growth and use of these fuels is basically equivalent to the amount of carbon dioxide absorbed during their consumption, making them a green and environmentally friendly energy source. This helps to reduce greenhouse gas emissions and combat climate change.
02. Help entrepreneurs save costs and improve competitiveness*
Secondly, biomass gasifiers have significant advantages in energy efficiency. Compared to traditional fossil fuel boilers, biomass gasification belongs to zero carbon energy, which not only has an advantage in emissions over fossil fuels, but also saves energy costs, reduces operating costs, and enhances competitiveness for enterprises by using biomass gasification furnaces.
03. Effectively reduced emissions of nitrogen oxides and particulate matter
In addition, biomass gasifiers do help reduce emissions of particulate matter and nitrogen oxides. The gas it produces is clean and environmentally friendly, with low sulfur, low dust, and no tar on site. Gas is fully burned in the boiler through a burner, thereby reducing the direct entry of large amounts of particulate matter and dust into the boiler when using biomass burners, and effectively reducing the emissions of nitrogen oxides and particulate matter, with less impact on the environment.
In summary, biomass gasifier is primarily based on the clean and zero carbon energy utilization, while helping enterprises reduce energy and operating costs. The ultimate goal is to reduce emissions, but this application technology is not developed to achieve emissions. Nowadays, biomass gasifiers have been widely used in fields such as electricity, heating, and industrial production, making important contributions to the utilization of renewable energy and environmental protection. With the continuous advancement of technology and the improvement of environmental protection requirements, the research and application of biomass gasifiers will continue to deepen in high-value and clean utilization, providing more technical support and application experience for China’s biomass energy utilization. It’s not just something done for a certain emission standard.
