Problems solved by technology

[0003] However, in the process of biomass combustion, because biomass contains more water and alkaline metal substances (especially crop straw), it is easy to cause ash accumulation and slagging to damage the combustion bed during combustion, and sintering may also occur.
High alkali metal content (K, Na) in biomass leads to low ash melting point of biomass, which brings many problems to the combustion process
In the process of combustion and utilization, high alkali metal content is an important factor that causes ash, slagging and corrosion on the heated area of ​​the boiler, which will directly reduce the life of the boiler and reduce thermal efficiency; at the same time, high alkali metal content is also easy to cause the agglomeration of bed materials , Slagging destroys the fluidization in the bed and deteriorates the combustion conditions

Embodiment 1

[0026] An anti-sintering type biomass fuel is composed of the following components in parts by weight:

[0027] 35 parts of corn stalks; 18 parts of rice straw; 8 parts of walnut shells; 7 parts of olive tree bark; 1 part of anti-caking agent.

[0028] The new anti-sintering agent used in the present invention is an anti-sintering agent composed of inorganic organic polymers, which can be converted into an acidic oxide ZnO with a large specific surface area and a porous appearance during the heating process, so that the ash melting temperature can be increased. Reduce slagging.

Embodiment 2

[0030] An anti-sintering type biomass fuel is composed of the following components in parts by weight:

[0031] 25 parts of corn stalks; 25 parts of rice straw; 10 parts of walnut shells; 10 parts of olive tree bark; 0.5 parts of anti-caking agent.

Embodiment 3

[0033] An anti-sintering type biomass fuel is composed of the following components in parts by weight:

[0034] 48 parts of corn stalks; 21 parts of rice straw; 5 parts of walnut shells; 5 parts of olive tree bark; 1.8 parts of anti-caking agent.

Abstract

The invention relates to the field biological energy sources, in particular to anti-sintering biomass fuel. The anti-sintering biomass fuel comprises the following ingredients in parts by weight: 25-50 parts of stalk, 15-25 parts of straw, 5-10 parts of walnut shell, 5-13 parts of bark and 0.5-2 parts of anti-sintering agent, wherein a molecular formula of the anti-sintering agent is C25H19O4N3Zn. Compared with the conventional biomass fuel particles compressed by the stalk, the biomass fuel has a low water content, a high combustion value and long combustion time, and can be converted into acidic oxide in situ by adding the anti-sintering agent; properties of the biomass fuel particles can be effectively adjusted; the biomass fuel particles have low possibility of slagging; and no harmful gas is emitted after combustion of the biomass fuel particles.

Description

technical field [0001] The invention relates to the field of biological energy, in particular to an anti-sintering type biomass fuel. Background technique [0002] Agricultural and forestry wastes, such as straw, sawdust, bagasse, rice bran, etc., are used as biomass fuels as green energy, and are fuels encouraged by national policies. From the perspective of life cycle, biomass burning releases carbon dioxide, which does not increase the carbon dioxide content in the atmosphere. Therefore, this carbon dioxide is not treated as a greenhouse gas according to national agreements. [0003] However, in the process of biomass combustion, because biomass contains more water and alkaline metal substances (especially crop straw), it is easy to cause ash accumulation and slagging to damage the combustion bed during combustion, and sintering may also occur. The high alkali metal content (K, Na) in biomass leads to a low ash melting point of biomass, which brings many problems to the...
