What is Biomass Gasification Process?


Using biomass as a starting material and oxygen, steam, or hydrogen as a medium, biomass is transformed into combustible gas by chemical reactions at high temperatures by biomass gasification technology. The combustible gas can be employed in industrial and agricultural production for things like methanol and ethanol synthesis, power generation, and heat delivery. Utilizing biomass and benefiting from the sanitized nature of biofuels may be done easily through biomass gasification. As a result of its ability to overcome the drawbacks of biomass, such as its difficulty in being burned and dispersed, as well as its ability to fully exploit the benefits of gas-fired power generation technology with its small equipment and reduced pollution, biomass gasification technology is one of the most efficient and cleanest ways to use biomass.

What three components make up the biomass gasification process?

1.Gasification of biomass, which turns solid biomass into gaseous fuel

2.Gas purification, where certain pollutants, such as ash, coke, and tar, are present in gas following gasification and must be eliminated by a purification system to ensure the proper operation of gas-fired power production equipment.

3.Gas-fired power generation, which produces energy using internal combustion engines or gas turbines. Power generating efficiency can be increased in some processes by incorporating waste heat boilers and steam turbines.

Biomass gasification process?

1.Biomass gasification uses a range of raw materials, such as agricultural and wood processing waste. As an example, use sawdust, tree branches, crop straw, rice husks, corn cobs, etc. Materials are plentiful and accessible.

2.The gasifier is where the gasification process takes place. The complexity of the reaction process varies with different gasifier types, reaction settings, raw material properties, grinding size, and other variables. However, they all have the subsequent procedures.

3.The raw material is burned in four stages: thermal decomposition, oxidation, reduction, and drying. The reduction layer has the greatest impact on the gas’s quality and yield.

Characteristics of biomass gasification power generation technology.

1.The technology for producing electricity from biomass gasification is totally flexible. Since biomass gasification power generation can use gas turbines, internal combustion engines, or even combine with waste heat boilers and steam power generation systems, it can select the appropriate power generation equipment based on the scale, ensuring reasonable power generation efficiency at any scale. The adaptability of biomass gasification technology may easily meet the requirements of dispersed biomass consumption.

2.The technology for generating electricity from biomass gasification is clean. A renewable energy source in and of itself, biomass can significantly lower the emission of noxious gases like CO2 and SO2. Since the gasification process typically produces little NOx (between 700 and 900 oC), NOx emissions can be successfully controlled.

3.The economics of biomass gasification power generation are strong. In general, biomass gasification power generation technology is the most cost-effective among all renewable energy te, and its flexibility can ensure its effectiveness and good economics in small scale applications. Additionally, the straightforward process of gas power generation and compact equipment also make biomass gasification power generation technology have smaller investment than other renewable energy power generation technologies. The total cost of producing electricity is comparable to that of producing tiny amounts of conventional energy.

What are the scales of biomass power generation?

Small, medium, and big are the three sizes of biomass gasification power generation systems, respectively.

1.Small biomass gasification power generation systems are straightforward and adaptable, primarily serving as self-sufficient generator sets for small and medium-sized businesses or as rural lighting systems. Since they only need a small quantity of one type of biomass, they can choose the best gasification equipment for the various shapes of biomass, with a general power output of 200 KW.

2.A medium-sized biomass gasification power generating system can be used to one or more distinct types of biomass, but a larger quantity of biomass is needed. It is mostly utilized as a self-provided power station for big and medium-sized industries or as a small-scale feed-in power station. The gasification process employed is mostly based on fluidized bed gasification, and pre-treatment is needed such as crushing and drying. The most common type of biomass gasification technology currently is the medium-sized biomass gasification power production system, which typically produces electricity between 500 and 3000 KW and is widely used and suitable.

3.A large-scale biomass gasification power generation system primarily performs as a feed-in power station, which can be used with a wider variety of biomass and requires a significant amount of biomass. It also requires the support of a specialized biomass supply center and pre-treatment center, which is the key component of biomass utilization in the future. Although it still seems extremely little compared to conventional energy, the power of big biomass gasification power generating systems is often above 5000KW, and it will be one of the primary ways to replace conventional energy power in the future when the development of biomass energy is mature.

What is the application prospect of biomass gasification?

After coal, oil, and natural gas, biomass is the fourth-largest energy source in the world in terms of energy equivalent. 14 percent of all energy consumed worldwide, and even more than 40 percent in poorer nations, comes from biomass.

According to Haiqi Energy, biomass energy will be significant in the future. Many nations are currently taking steps to reform their energy systems and give biomass energy development top priority. 15% of the total energy consumed in Europe comes from biomass energy. It is anticipated that biomass will replace 20% of fossil fuels. In the future, there will be an increase in the number of biomass power plants operating in Europe, the United States, Canada, and Japan.
