On the morning of August 28, the leaders of Xingtai Investment Promotion Bureau visited Debo to investigate the biomass gasification central heating combined biochar production project. After listening to the report, the leaders made a good summary of the Debo model: 1. No coal will be approved for new projects, and the coal projects in the early stage will be stopped; The cost of natural gas is not only high, but also there is often a gas shortage, which makes enterprises miserable. 2. The new park has no supporting heat source center, and the government has no way to attract investment, which hinders the local economic development. 3. The biomass gasification project has changed the traditional direct combustion utilization mode of biomass. The gasification is cleaner, larger or smaller, more flexible, diversified products and high value. It not only reduces the energy consumption cost of enterprises, but also helps to reduce emission and realize carbon neutralization, but also helps the local government to deal with agricultural and forestry wastes, increase financial revenue and boost investment attraction. 4. Establish a unified heating center and cancel small bulk boilers to facilitate the safety management of the park.
