Calorific value is an important characteristic index of solid biomass fuel. When using thermal energy of solid biomass fuel, its calorific value must be accurately understood. For example, in the combustion of power generation boilers, the accuracy of calorific value measurement is directly related to the combustion efficiency of boilers, and affects the economic benefits of power plants.
The use of solid biomass fuel instead of coal combustion not only solves the problem of energy regeneration, but also reduces the emissions of pollutants caused by coal combustion. At the same time, energy saving and emission reduction are achieved, which meets the requirements of sustainable development. Many countries have intensified the research and development of biomass energy. The research on the test methods of solid biomass fuel characteristics and the formulation of relevant standards are the basic work for the scientific and efficient utilization of solid biomass fuel energy. At present, neither the International Organization for Standardization nor China has established mature and effective standards for the determination of calorific value of solid biomass fuels. The current technical specifications of the United States and the European Union are not yet perfect. The Calorific Value Measurement Method for Biomass Fuels was formulated in 1980s in China. At that time, it was restricted by conditions and insufficient experimental research. It has been abolished. This project adopts the oxygen bomb calorimetric method which is widely used in the world to study the calorific determination method suitable for the characteristics of solid biomass fuels in China, and formulates corresponding national standards to meet the needs of the rapid development of solid biomass fuels application technology, and to improve the development and efficient utilization of solid biomass fuels in China.
