Embodiment 1

[0022] (1) Collection of raw materials: After the tubers of Jerusalem artichoke in the field are mature, and the aboveground leaves and stems of Jerusalem artichoke are withered and yellow, use a straw harvester to harvest the stems of Jerusalem artichoke;

[0023] (2) Drying and impurity removal: dry the harvested Jerusalem artichoke stalks in the air, control the moisture content of the stalks below 15%, and pass the stalks through a vibrating sieve to remove impurities such as dust mixed on the stalks;

[0024] (3) Raw material pulverization: the Jerusalem artichoke stalk that removes dust and impurity is pulverized into 20 purpose scraps with pulverizer, standby;

[0025] (4) Mixing: In parts by weight, mix 70 parts of Jerusalem artichoke straw scraps, 20 parts of bad coal, 3 parts of calcium oxide, 4 parts of diatomaceous earth, 1 part of combustion aid, 1 part of sulfur-fixing agent, and 1 part of bentonite uniform; wherein, the combustion aid is a mixture of potassium n...

Embodiment 2

[0031] (1) Collection of raw materials: After the tubers of Jerusalem artichoke in the field are mature, and the aboveground leaves and stems of Jerusalem artichoke are withered and yellow, use a straw harvester to harvest the stems of Jerusalem artichoke;

[0032] (2) Drying and impurity removal: dry the harvested Jerusalem artichoke stalks in the air, control the moisture content of the stalks below 13%, and pass the stalks through a vibrating sieve to remove impurities such as dust mixed on the stalks;

[0033] (3) Raw material pulverization: the Jerusalem artichoke stalk that removes dust and impurity is pulverized into 30 purpose scraps with pulverizer, standby;

[0034] (4) Mixing: In parts by weight, mix 79 parts of Jerusalem artichoke straw scraps, 15 parts of bad coal, 2 parts of calcium oxide, 2 parts of diatomite, 0.5 parts of combustion enhancer, 1 part of sulfur-fixing agent, and 0.5 parts of bentonite uniform; wherein, the combustion aid is a mixture of potassium...

Embodiment 3

[0040] (1) Collection of raw materials: After the tubers of Jerusalem artichoke in the field are mature, and the aboveground leaves and stems of Jerusalem artichoke are withered and yellow, use a straw harvester to harvest the stems of Jerusalem artichoke;

[0041] (2) Drying and impurity removal: dry the harvested Jerusalem artichoke stalks in the air, control the water content of the stalks below 14%, and pass the stalks through a vibrating screen to remove impurities such as dust mixed on the stalks;

[0042] (3) Raw material pulverization: the Jerusalem artichoke stalk that removes dust and impurity is pulverized into 30 purpose scraps with pulverizer, standby;

[0043] (4) Mixing: In parts by weight, mix 60 parts of Jerusalem artichoke straw scraps, 30 parts of bad coal, 2.5 parts of calcium oxide, 4 parts of diatomaceous earth, 1 part of combustion aid, 2 parts of sulfur-fixing agent, and 0.5 parts of bentonite uniform; wherein, the combustion aid is a mixture of potassi...

Abstract

The invention discloses a jerusalem artichoke straw fuel bar and a preparing method thereof. The jerusalem artichoke straw fuel bar is prepared from, by weight, 50-80 parts of jerusalem artichoke straw, 15-30 parts of craw coal, 1-3 parts of calcium oxide, 2-4 parts of kieselguhr, 0.5-1 part of combustion improver, 1-3 parts of sulfur-fixing agent and 0.5-1.5 parts of bentonite. The characteristic of high burning caloric value of jerusalem artichoke straw is fully utilized, the combustion supporting component is added to the fuel bar, additives including calcium oxide and kieselguhr are added, the clinkering rate and corrosiveness of jerusalem artichoke straw are reduced, the prepared jerusalem artichoke straw fuel bar can be widely applied to industrial and civilian production, the utilization rate of jerusalem artichoke straw is increased, and extension and development of the jerusalem artichoke industrial chain are promoted.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a Jerusalem artichoke straw fuel rod and a preparation method thereof. Background technique [0002] At present, the energy and environment of the whole country and the world are facing a severe crisis. Therefore, changing the energy consumption structure and preventing and controlling air pollution have become important issues facing the sustainable development of society and economy. Biomass energy, as a renewable clean energy, has attracted more and more attention from all parties. At present, the utilization rate of straw resources in my country is low, and they are usually burned in farmland, which not only causes waste of resources, but also causes serious pollution to the environment. [0003] Jerusalem artichoke (Helianthus tuberosus) is a perennial herbaceous plant of the genus Sunflower in the family Asteraceae, also known as Jerusalem artichoke, devil ginger, ar...
