With the increasing global demand for renewable energy, biomass energy, as a clean and sustainable energy form, has been widely concerned. Among them, biomass briquetting technology has become an important means of biomass energy utilization because it can process loose crop straws, forestry wastes and other raw materials into high-density, easy-to-store and easy-to-transport fuels. However, this technology still faces many challenges in practical application.

Challenges of biomass briquetting technology in application

1. Technical problems brought by the diversity of raw materials

There are many kinds of biomass raw materials, including rice husk, corn stalk, sawdust, etc., and their chemical composition and physical characteristics are quite different. This diversity puts forward higher requirements for the adaptability of briquetting machine. The water content and fiber structure of different raw materials will directly affect the forming effect and combustion performance of briquette. Therefore, how to develop a universal briquetting machine that can adapt to a variety of raw materials is a major difficulty in current technology.

2. Energy consumption and economic problems

Biomass briquette machine needs to consume a lot of energy during its operation, especially when it is molded under high temperature and high pressure, the energy consumption problem is particularly prominent. In addition, the initial investment cost of equipment is high, which makes it difficult for some small enterprises or farmers to bear. How to reduce equipment energy consumption and improve production efficiency, so as to maximize economic benefits, is an important direction of technology research and development.

3. Finished product quality and market competitiveness

The quality of biomass briquette fuel is directly related to its market competitiveness. At present, some briquette fuels have problems such as uneven density and insufficient mechanical strength, which affect their storage and transportation performance. In addition, compared with traditional fossil fuels, the calorific value of biomass fuels is relatively low, which also limits its wide application in industrial fields.

4. Insufficient environmental protection and policy support

Although biomass energy is regarded as an environment-friendly energy source, there may still be some pollution during its production and use, such as smoke and dust emission. In addition, in some areas, the lack of relevant policy support and subsidies has affected the development speed of the industry.

Future development direction

In order to meet these challenges, biomass briquetting technology needs to make breakthroughs in the following aspects: First, develop intelligent and modular briquetting equipment to meet different raw materials and production needs; The second is to optimize the briquetting process, reduce energy consumption and improve the quality of finished products; The third is to promote policy support and increase subsidies and promotion of biomass energy industry. At the same time, strengthening technological innovation and international cooperation is also an important means to promote the development of the industry.

In a word, although biomass briquetting technology faces many challenges, with the technical progress and policy guidance, its application prospect in the field of clean energy is still broad. By constantly overcoming difficulties, this technology is expected to make greater contributions to global energy transformation and environmental protection.
