Introduction

Analysis of the core content of the standard

LY/T 3243-2020 standard systematically standardizes the mechanical strength and component analysis methods of biomass molded fuel, mainly including:

Rotational wear principle of crushing resistance test
Determination of four major indicators of industrial analysis
Difference calculation method of fixed carbon

Key technologies for crushing resistance test

Elements	Parameter requirements	Instrument configuration
Test box size	300×125×300mm	Steel/Aluminum test box
Rotation conditions	40±1r/min, 500 revolutions	Rotation device with tachometer
Screening standard	Aperture = 2/3 fuel diameter	ISO3310-1 test sieve

Application Example: A straw pellet plant used a 3.15mm round hole sieve for crushing resistance test and the measured DU value was 97.5%, which meets the commercial grade requirement of ≥95% specified in NY/T 1880.

Comparison of Industrial Analysis Methods

Indicators	Key Points of the Method	Temperature Control	Precision Requirements
Moisture	Nitrogen/Air Drying Method	105±1℃	Repeatability≤0.15%
Ash Content	Stage Temperature Rising	550±10℃	Repeatability≤0.2%
Volatile Matter	Isolated Air Heating	900±10℃	Repeatability≤0.6%

Suggestions for the implementation of the standard

Instrument calibration:The constant temperature zone of the muffle furnace should be measured and mapped annually, and the thermocouples should be calibrated regularly
Sample processing:General analysis samples with a particle size of less than 1mm need to be air-dried
Data correction:The moisture content (M_ad) needs to be deducted from the volatile matter result
Quality control:When determining the ash content, a 15mm ventilation gap should be maintained at the furnace door

Technical evolution:Compared with GB/T 28731, this standard adds a new test method for anti-shattering, and uses the nitrogen drying method as the arbitration method, which effectively solves the problem of easy oxidation of biomass fuels.
