Interpretation of the National Standard of the People's Republic of China GB/T 30366-2024 "Biomass Terminology"
1. Analysis of Standard Formulation Background and Technological Evolution
This standard is a revision of GB/T 30366-2013. The main updates include:
- Changes to the scope definition (see Chapter 1)
- Deleted terms such as "softening temperature of ash melting"
- Added 9 new terms such as "cork" and "cork"
- Added the chapter "Analysis and Physical and Chemical Properties Testing of Biomass Raw Materials"
- Added 8 new terms such as "wet basis moisture content" and "dry basis moisture content"
2. Comparison of Standard Frameworks
| Chapters | 2013 Edition Contents | 2024 Edition Additions/Revisions |
|---|---|---|
| Scope | Defines biomass-related terms, applicable to production, circulation, testing and other fields. | Updated the scope definition, and added content such as "biomass raw material analysis and physical and chemical performance testing". |
| Terms and Definitions | Covering basic terms such as agricultural biomass and forestry biomass. | Added 9 new terms such as "cork" and "softwood", and refined the classification of biomass. |
| Normative References | None | None |
3. Core Terminology Analysis and Practical Application Cases
3.1 Biomass
Definition:Organic matter formed by photosynthesis of green plants directly or indirectly.
Practical Application:For example, in the development of biomass energy, wood, bamboo, straw, etc. can all be used as biomass sources.
3.2 Energy Plant
Definition:Cultivated plants grown for energy production, including corn, sugarcane, switchgrass, etc.
Practical application:For example, in biodiesel production, soybean and rapeseed are important energy plant sources.
3.4 Ash fusion test
Definition:A method used to detect the softening and melting behavior of ash.
Practical application:In the design of biomass combustion equipment, this test helps to evaluate the high temperature performance of the fuel.
4. Implementation suggestions
Standard application suggestions
- In the research and development of biomass products, strictly follow the definition of terms for classification and naming.
- In testing and evaluation, refer to the newly introduced "biomass raw material analysis and physical and chemical properties testing" method.
- In policy formulation, cite this standard to regulate the development of the biomass energy industry.
Technical Improvement Direction
- It is recommended to further refine the classification system of "biomass materials".
- It is recommended to increase the standardization research on emerging biomass technologies (such as air source heat pump drying).
