Determination of ash in forestry biomass feedstock analysis
1 Scope
This standard specifies the method for the determination of ash in forestry biomass raw materials.
This standard applies to the determination of ash content in forestry biomass raw materials such as wood and bamboo.
2 Normative references
The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article
Pieces. For undated references, the latest version (including all amendments) applies to this document.
GB/T 35814-2018 Analysis of forestry biomass feedstock sample processing methods
GB/T 35820-2018 forestry biomass raw material analysis method sampling method
GB/T 36055-2018 Analysis method of forestry biomass feedstock moisture content determination
3 Principle
In the strict control of time, sample quality, equipment specifications, temperature (550 ± 10) °C and other conditions, by measuring the sample heated in the air
The ash content was determined as the percentage of post-residues as a percentage of the total dry sample mass.
4 Instruments and Devices
4.1 Muffle furnace
It is required to have temperature-programmed control, to reach the specified temperature within a specified time, and to maintain a constant temperature. The ventilation rate in the muffle furnace is
5 to 10 times per minute to satisfy the lack of oxygen in the combustion process of the biomass feedstock during the heating process.
4.2.
Made of inert material, the size of the sample after loading into the sample, the bottom density of the sample is not more than 0.1g/cm2.
4.3 Balance
Sensing amount 0.1mg.
4.4 Dryer
A desiccator equipped with a blue discolored silica gel or granular anhydrous calcium chloride desiccant.
4.5 Drying oven
With automatic temperature control and air blowing device, the temperature can be controlled within the range of (105 ± 2) °C.
4.6 Electric furnace
With temperature regulator.
