Foreword
This standard rule according to GB/T 1.1-2009 given draft.
This standard uses redrafted EU law revision using the following specifications. CEN/TS14774-3.2004 "solid biomass fuel water
Determination of points oven drying method - Part 3. Moisture in general analysis sample "; CEN/TS14775.2004" solid biomass fuel
Determination of ash material "; CEN/TS15148.2005" volatile solid biomass fuels determination. "
This standard is above the EU compared to the technical specifications made adjustments in the structure of the standard listed in Appendix A of this standard and above EU TECHNOLOGY
Operation control specification clauses numbered list.
The presence of the above-mentioned EU standards and technical specifications technical differences compared to the terms of these differences has been involved through its outer margins
Vertical single-line position (|) have been marked, in Appendix B gives the corresponding list of technical differences and their causes.
The standard proposed by China Coal Industry Association.
This standard coal by the National Standardization Technical Committee (SAC/TC42) centralized.
This standard was drafted. CCRI coal analysis laboratory.
1 Scope
This standard specifies the method for determination of water content of solid biomass fuel, ash and volatile matter, fixed carbon and the calculation method.
This standard applies to solid biomass fuel.
2 Sample
Solid biomass fuels in general analysis sample. air-dry state to achieve a particle size of < 1mm or smaller particle size solid biomass fuels
Sample.
3 Determination of moisture
This chapter provides two solid biomass fuel moisture measurement method. A method in which nitrogen is drying, air drying method B
Law. If the sample material at 105 degrees C +/- 2 degrees C easily oxidized, should be selected method A.
Useful encountered general analytical sample moisture correction and conversion in the arbitration group analysis, the application of measurement methods A general analysis test
Like water.
3.1 Method A (nitrogen drying)
3.1.1 Method summary
Weigh a certain amount of solid biomass fuels in general analysis sample, placed in 105 degrees C +/- 2 degrees C oven dried in dry nitrogen stream
To constant mass and then calculate the moisture content according to the mass loss of the sample.
3.1.2 Reagents and Equipment
3.1.2.1 Nitrogen. 99.9% purity, oxygen content less than 0.01%.
3.1.2.2 anhydrous calcium chloride (HGB 3208). chemically pure, granular.
3.1.2.3 color gel. industrial supplies.
3.1.2.4 Small oven space. tight box, having a smaller free space, a gas inlet and outlet, and automatic temperature control device, can protect
Hold the temperature at 105 degrees C +/- 2 degrees C.
3.1.2.5 glass weighing bottle. diameter 40mm, high 25mm, and ground with a tight flap (see Figure 1).
Millimeters
1 glass weighing bottle
3.1.2.6 dryers. built-in granular silica gel or anhydrous calcium chloride.
