Method for testing mechanical durability of biomass granular fuel

Abstract

The invention discloses a method for testing the mechanical durability of biomass granular fuel. The method comprises the following steps: (1) preparing a sample; (2) carrying out fine material screening on the sample in a mechanical rocking sieve; (3) weighing the mass ME of the biomass granular fuel retained on a test sieve by using a balance, and putting the biomass granular fuel into a rotating box of a mechanical durability tester; (4) starting a mechanical durability tester such that the rotating box rotates, wherein the rotating time of the rotating box is determined according to the type of the biomass fuel; (5) taking out the biomass granular fuel in the mechanical durability tester, and putting the biomass granular fuel into the mechanical rocking sieve again for fine material screening; (6) weighing the mass MA of the biomass granular fuel retained on the test sieve by using the balance; (7) calculating the mechanical durability DU of the biomass granular fuel by using a formula DU = 100 * MA / ME (%); and (8) repeating the steps (2)-(7) for more than 6 times, and calculating the average value of results to be accurate to 1.0%. According to the invention, the testing of the mechanical durability of the biomass granular fuel is realized.

Description

technical field [0001] The invention relates to the technical field of fuel testing, in particular to a method for testing the mechanical durability of biomass pellet fuel. Background technique [0002] At present, most of the fuels are fossil energy such as kerosene, oil, natural gas, etc., which are non-renewable resources, which are gradually exhausted due to the decline of large-scale exploitation by human beings, and when they are burned, they will emit a large amount of greenhouse gases, causing serious environmental pollution. [0003] Biomass pellet fuel is a renewable and clean fuel, and mechanical durability is a key indicator reflecting the physical properties of biomass pellet fuel, but there is currently no effective equipment and method for testing the mechanical durability of biomass pellet fuel. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a method for testing the mechanical durability of biomass particle fuel, so as ...
