Problems solved by technology

[0006] The biomass fuels produced in the prior art often have the problem of low calorific value, which is largely caused by insufficient combustion; Production accidents bring serious hidden dangers to operators and increase production costs
Therefore, the present invention aims to provide a biomass fuel and its production process, in order to solve the problem of low calorific value but high slagging rate of conventional biomass fuel

Embodiment 1

[0054] A production process of biomass fuel, consisting of the following steps:

[0055] Z1 crushes crop straw residues and dries them to obtain residue powder;

[0056] Z2 Mix the residue powder and anti-slagging agent, then press and cut to obtain granular biomass fuel.

[0057] In the Z1 process: the crop stalk residue is a mixture of bagasse, sorghum stalk, cassava residue, and corn stalk in a mass ratio of 1:1:1:1; the drying temperature is 75°C, and the drying time is 3h; the fiber length of the residue powder is ≤7mm.

[0058] In the Z2 process: the mass ratio of the residue powder to the anti-slagging agent is 19:1; the pressure of the pressing is 13MPa, and the holding time is 35min; the size of the biomass fuel is 2mm×2mm× 2mm.

[0059] The preparation method of described anti-slagging agent is:

[0060] E1 adopts two sizes of alumina grinding balls to dry-grind the ore through a planetary ball mill to obtain ore powder;

[0061] E2 washes the ore powder obtaine...

Embodiment 2

[0069] It is basically the same as Example 1, except that the wetting agent is polyoxyethylene sorbitan laurate.

Embodiment 3

[0071] It is basically the same as Example 1, except that the wetting agent is polyethylene glycol diacrylate.

Abstract

The invention discloses a biomass fuel and a production process thereof. The production process comprises the following steps: crushing and drying crop straw residues to obtain residue powder, then mixing the residue powder with an anti-slagging agent, and then pressing and cutting to obtain granular biomass fuel. A preparation method of the anti-slagging agent comprises the following steps: carrying out ball milling on ore to obtain ore powder; cleaning the ore powder, and then standing, centrifuging, filtering, drying and crushing; mixing the ore powder, a foaming agent and a wetting agent, and stirring to obtain a to-be-sintered blank; and sintering, cooling to room temperature, and crushing to obtain the anti-slagging agent. The biomass fuel obtained by the specific process has the advantages of high calorific value and low slagging rate.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a biomass fuel and a production process thereof. Background technique [0002] Today, biomass has a variety of classification methods, which can be generally summarized into the following aspects: wood and forest industrial waste, agricultural waste, aquatic plants, oil crops, urban and industrial organic waste, and animal manure. Biomass energy has the characteristics of extremely high reserves, simple and easy-to-control acquisition methods and combustion operations, less pollution and damage to the environment, and fewer toxic and harmful products produced after combustion. The carbon dioxide released from the combustion of biomass fuel is almost equivalent to the mass of carbon dioxide absorbed by photosynthesis during its growth, that is, mass / element conservation. Therefore, it can be considered that the carbon dioxide produced when burning biomass fuel is zero, that i...
