The present invention uses straw as biomass to compound the biomass briquette, and the straw has the advantages of low cost, little moisture and high volatile component. The biomass industrial briquette has the advantages of easy ignition, quick combustion speed, no smoke, sulfur solidification, sufficient combustion of the briquette, low carbon content of ash and less possibility of slag coagulation.
Description
Technical field
The present invention is applied to Thermal Power Engineering Field, particularly a kind of biomass type briquette prescription at Huang Ling bituminous coal.
Prior art
Shaped coal technology is that the coal of one or more different in kinds is mixed into a certain proportion of binding agent, sulphur-fixing agent, leavening agent etc. according to self character through scientific matching, make technical indicators such as its thermal value, volatile matter, sulfur-fixing rate reach predetermined value, through pulverizing, be mixed, technological process such as compression moulding is processed into the solid-state industrial fuel that has certain geometrical shape and cold strength and good combustion characteristic and environment protecting are arranged.Biomass energy is minimum in the commercial shared ratio of energy structure of using of China, and it mainly is used as primary energy source and is utilized in the rural area, but most of burning or discarded that directly acted as a fuel utilizes level low, wastes seriously, and contaminate environment.But biomass coal is meant and is broken into certain particle size and is dried to a certain degree coal and biomass-burning that blending by a certain percentage adds a small amount of sulphur-fixing agent, utilizes xylogen in the biomass, Mierocrystalline cellulose, hemicellulose etc. and the difference compacting of caking property of coal to form.Use that clean coal technology combines with biomass energy and the biomass fuel burning technology that grows up is exactly the biomass coal technology, this technology combines non-renewable fossil energy and renewable energy source cleverly, very meet the coal in China abundant national conditions of biomass resource simultaneously of preponderating, have very strong realistic meaning.But the ature of coal of different areas has very big-difference, needs corresponding prescription at different coals and just can reach many economic technology requirements.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, a kind of biomass coal at Huang Ling bituminous coal is provided, with the common Huang Ling coal in this area is raw coal, select the straw that the source is wide, cost is low, moisture is few, volatile matter is big to prepare biomass coal as biomass, this biomass industrial shaping coal easily catches fire combustionvelocity; Do not smolder, can consolidate sulphur; The moulded coal sufficient combustion, the low and not slagging scorification of ash content carbon.
Technical scheme of the present invention is achieved in that
The present invention is a raw coal with Huang Ling coal, and adopting straw is the compound binding agent of main component, and its composition and quality percentage composition are as follows:
Bituminous coal 66-74%
Calcium based sulphur-fixation reagent 7-9%
Straw binding agent 16-20%
Cementitious additives wilkinite 0.6-1.4%
Cementitious additives tar 2-4%
It is Huang Ling bituminous coal that the present invention adopts bituminous coal, and its calorific value is lower, and sulphur content is higher, but its volatile content is higher, and flammability is better.
Send Arca Subcrenata to pulverizer and pulverize, adopting and pulverizing the back is the shell powder of 0.3～0.5mm for particle diameter, as sulfur capture agent for briquette.
The solid sulphur of shell is active high, and long reaction time, calcium utilization and desulfuration efficiency are all very high.Its best desulfurization temperature is 900～1050 ℃, and temperature range is big; Have sintering resistance energy preferably, behind the constant temperature sintering, calcium utilization is constant substantially; Shell has good microvoid structure, helps gaseous diffusion and carries out desulphurization reaction to its inside, and calcium utilization is higher.Use shell and have very big economic benefit and environmental benefit as sulphur-fixing agent.
Select the compound binding agent of straw main raw material.Straw source is wide, cost is low,, moisture is less, volatile matter is bigger, generally about 18MJ/kg, ignition temperature lower (325 ℃) produces when helping burning by " vesicular structure " calorific value, and calorific value is higher, has very by force for the coal effect, can well improve coal saving rate.The ligation of undecomposed fibrous matter in moulded coal that contains in the straw binding agent is extremely important, is the big characteristics that the straw binding agent is different from other binding agents.When reached about 4 hours heat-up time, it is the strongest that briquette strength reaches.
The cementitious additives wilkinite has good adhesive property, and it is added with the raising that is beneficial to adhesive strength, and along with the raising of wilkinite addition, the amplitude that briquette strength improves is big more.
Cementitious additives coal tar is a kind of black or the chocolate viscous liquid that obtains in the dry distillation of coal process, has special odor, and is flammable and be corrosive.Be a kind of complex mixture of hydrocarbon polymer of high aromaticity, and be the hydrophobic nature material that calorific value is also higher, the coal tar calorific value that uses here is 36.84MJ/kg.
The coal tar of interpolation about 3% and about 1% wilkinite in the moulded coal of basic straw adhesive preparation, research according to document, the fall strength of briquette of the moulded coal that this compound straw binding agent is made and thermostability are all more than 90%, abrasive wear resistance is more than 80%, oven dry ultimate compression strength meets the boiler service requirements fully more than 3.31 * 104Pa.
