In 2004, there were 25 provincial-level power grids in China that had power cuts. The maximum power gap in the winter and summer power peaks in China exceeded 30 million kilowatts. Many generator sets were shut down due to insufficient coal supply. In addition, there are still 30 million people in China who do not have access to electricity.

In 2004, there were 25 provincial-level power grids in China that had power cuts. The maximum power gap in the winter and summer power peaks in China exceeded 30 million kilowatts. Many generator sets were shut down due to insufficient coal supply. In addition, there are still 30 million people in China who do not have access to electricity. The development of biomass-forming pellet fuel industry will provide necessary supplements to coal. The construction of distributed small and medium-sized thermal power plants will effectively alleviate the tension between power supply and heat supply, and will have far-reaching significance for China's comprehensive construction of a well-off society. Futong New Energy produces and sells straw pellet machine straw briquetting machine to suppress biomass pellet fuel.
With the acceleration of urbanization, urban residents are close to 600 million people, causing the pressure on urban heating in China to gradually increase. Many of the newly built communities are mostly outside the city, and the heat pipe network is difficult to reach, or the heat loss is serious and difficult to sustain. In order to meet the living needs of residents, it is necessary to adopt district heating measures, which are subject to environmental protection restrictions. Most of them are heated by natural gas or electric fuel, and the heating efficiency is low. Either the heating cost is too high, or the heating plant is operating at a loss, neither of which is a long-term solution. After the introduction of China's "Renewable Energy Law", straw power generation has a legal guarantee. The development of straw pellet fuel cogeneration can meet the heating demand and generate electricity income, and the heating distance is short, and the construction investment is small. It is a win-win development and utilization of renewable energy solutions.
