Embodiment 1

[0035] see figure 1 , the method for rapid determination of ash content in woody biomass fuel according to the first embodiment of the present invention, comprising:

[0036] Step 1, take an ash dish and burn it for 2 to 3 hours until it has a constant weight. During the burning process, the ash dish is gradually heated from room temperature to an ashing temperature of 575 ° C. After the burning is completed, the constant weight ash dish is weighed. The mass is recorded as m 0 , the ash dish after weighing is placed in a desiccator for backup;

[0037] In step 2, the tested biomass fuel is made into granules with a particle size of less than 0.2 mm, and a sample of tested biomass fuel with a mass of 0.50±0.05 g is taken out and spread evenly in the ash dish described in step 1, so that it is The mass per square centimeter is less than 0.15g, and the ash dish containing the tested biomass fuel sample is weighed, and its mass is recorded as m 1 ;

[0038] Step 3, put the ash...

Embodiment 2

[0048] The rapid determination method of the second embodiment of the present invention is basically the same as that of the first embodiment, and their differences are: the ashing temperature of the second embodiment is 575°C, the mass of a tested biomass fuel sample is 0.75g, and the horse-fired furnace is opposite to the tested biomass fuel sample. The burning time of biomass fuel samples was measured as 50min.

Embodiment 3

[0050] The rapid determination method in Example 3 of the present invention is basically the same as that in Example 1. The differences are: the ashing temperature of Example 3 is 600°C, the mass of a tested biomass fuel sample is 0.75 g, and the horse-fired furnace is opposite to the tested biomass fuel sample. The burning time of biomass fuel samples was measured as 50min.

Abstract

The invention discloses a rapid determination method for ash content in a lignocellulosic biomass fuel. The method comprises the following steps: firing a measured biomass fuel sample of which the mass is 0.50-075g at the ashing temperature of 575-600 DEG C for 40-50 minutes, recording the mass of the measured biomass fuel sample before and after firing, so as to calculate the air-dried ash content in the measured biomass fuel. By adopting the method, the ash content of the biomass fuel can be quickly and efficiently determined, and the method has the advantages of high measurement result accuracy and low implementation cost. The invention also discloses a determination device for the ash content in the lignocellulosic biomass fuel by using the rapid determination method.

Description

technical field [0001] The invention relates to a rapid determination method for ash content in wood biomass fuel, and also relates to an automatic determination device for ash content in wood biomass fuel using the rapid determination method. Background technique [0002] Because biomass has the dual properties of being environmentally friendly and renewable, biomass fuel is considered to be the resource with the most potential to replace oil. According to statistics, the existing biomass resources in my country are more than 650 million tons of standard coal, which is considered to be the most abundant resource in the world. Potential renewable energy resources. The basic properties of biomass, such as industrial analytical indicators, have a crucial impact on biomass fuel collection, processing, application of feedstock, and selection of combustion boilers. Biomass ash is the ash material remaining after the combustion of volatile matter and fixed carbon in biomass fuel, ...
