Embodiment 1

[0014] The biomass fuel provided by the invention is prepared from the following raw materials in parts by weight: 80-90 parts of ramie bone, 10-15 parts of attapulgite clay powder, and 0.5-1 part of calcium phosphate.

[0015] The preparation method of biomass fuel as described above, comprises the following steps:

[0016] (1) Crush the ramie bone; carbonize, the carbonization temperature is 300-400°C, and the time is 2-3h; if the carbonization temperature is too high or too low, it will affect the generation of ash and the calorific value of combustion during the combustion process, and then carry out the second Second crushing; passing through 80-120 mesh sieve;

[0017] (2) Mix the pulverized carbonized ramie bone with attapulgite clay powder, calcium phosphate and water;

[0018] (3) Molded and dried until the water content is less than 12%.

Embodiment 2

[0020] The biomass fuel provided by the invention is prepared from the following raw materials in parts by weight: 85 parts of ramie bone, 12.5 parts of attapulgite clay powder, and 0.75 part of calcium phosphate.

[0021] The preparation method of biomass fuel as described above, comprises the following steps:

[0022] (1) Pulverize the ramie bone; carbonize, the carbonization temperature is 350°C, and the time is 2.5h; if the carbonization temperature is too high or too low, it will affect the generation of ash in the combustion process and the calorific value of combustion, and then carry out the second pulverization; Pass through 120 mesh sieve;

[0023] (2) Mix the crushed carbonized ramie bone with attapulgite clay powder, calcium phosphate and water;

[0024] (3) Molded and dried until the water content is less than 12%.

[0025] Take the dried molded fuel. After testing, the combustion heat energy value is 5720kcal / kg, the ash content is 1.1%, and the slagging rate i...

Embodiment 3

[0027] The biomass fuel provided by the invention is prepared from the following raw materials in parts by weight: 88 parts of ramie bone, 13 parts of attapulgite clay powder, and 1 part of calcium phosphate.

[0028] The preparation method of biomass fuel as described above, comprises the following steps:

[0029] (1) Crush the ramie bone; carbonize, the carbonization temperature is 380°C, and the time is 2 hours; if the carbonization temperature is too high or too low, it will affect the generation of ash in the combustion process and the calorific value of combustion, and then carry out the second crushing; 80 mesh sieve;

[0030] (2) Mix the crushed carbonized ramie bone with attapulgite clay powder, calcium phosphate and water;

[0031] (3) Molded and dried until the water content is less than 12%.

[0032] Take the dried molded fuel. After testing, the combustion heat value is 5660kcal / kg, the ash content is 1.2%, and the slagging rate is 1.7%. Put it in an 80% humidit...

Abstract

Disclosed is biomass fuel. The biomass fuel is prepared from, by weight, 80-90 parts of ramie bone, 10-15 parts of attapulgite clay powder and 0.5-1 part of calcium phosphate. The burning heat energyof the obtained biomass fuel reaches up to about 6,000 kcal/kg, the ash content is smaller than 1.3%, the slag bonding rate is smaller than 2%, and the storage period is long.

Description

technical field [0001] The invention belongs to the technical field of biofuels, and in particular relates to a biomass fuel that burns completely and is not easy to slagging. Background technique [0002] With the decrease of coal and natural gas resources and the increasing environmental pollution, new energy fuels obtained from biomass are currently a research hotspot. Biomass energy mainly uses raw materials such as agricultural waste, logging residues, factory and domestic waste, and sludge to process into end products such as biomass briquette fuel and liquid fuel. Biomass briquette fuel raw materials are easy to obtain, and the emission of harmful substances such as smoke and sulfur dioxide is less, but it is prone to slagging and high ash content during combustion, and due to the existence of biological organic matter, it is easy to mold in a humid environment, which affects combustion efficiency. Contents of the invention [0003] The object of the present invent...
