Abstract

The invention relates to a compound biomass granular fuel. The invention aims at overcoming the problems of low ash melting point, serious coking and the like of the existing maize straw biomass granular fuel and providing a novel compound biomass granular fuel. The formula of the fuel comprises the following components by weight percent: 70-75% of maize straw powder, 24-30% of rice hull powder and 0.5-1% of calcium oxide powder. The manufacturing method comprises the following steps: firstly processing maize straws and rice hulls into fine powder by using a smashing machine; then adding the calcium oxide powder, uniformly mixing according to the stipulated weight percent; and sending into a particle forming machine for extruding the mixture into the cylindrical granular fuel with the diameter of 6-10mm. The biomass fuel is the compound biomass granular fuel with excellent combustion characteristic, high ash melting property and low fluxing trend, and can be widely applied in various biomass combustion devices.

Description

A kind of compound bio matter granular fuel
Technical field
The present invention relates to a kind of renewable biomass shaped fuel, it is a kind of agricultural crop straw of using, the compound bio matter granular fuel that rice husk and additive are made.
Background technology
At present, the energy and environmental problem have become the focus that the whole world is paid close attention to, though oil, coal and Sweet natural gas are still the main source of fuel so far,, develop clean renewable energy source and become urgent subject along with the exhaustion day by day of fossil energy and being on the rise of environmental problem.Under this background, biomass energy is as the only renewable energy source that stores and transport, and its efficient conversion and clean utilization are subjected to the attention in the world day by day.
Biomass energy is to utilize green plants that sun power is stored in the intravital natural resources of plant by photosynthesis, is a kind of cheap storing mode of sun power.Utilize the quantity discharged of biomass energy can not realize the zero release of carbonic acid gas above the carbon amount that is absorbed of its growing period.On the strategy of global sustainable development, the energy potentiality of performance biomass energy and environmental potential are and are important.China is a large agricultural country, and biomass energy is very abundant, and biomass energy is the main energy sources in rural area, utilizes situation to fall behind, and pollutes big.China can produce more than 600,000,000 ton of agricultural crop straw every year, as all being used for burning, can amount to the calorific value of about 300,000,000 tons of standard coals.The advantage of biomass fuel is: 1. some geographic grate furnaces of the calorific value of biomass and China are worked as (about 18000kJ/kg) with coal facies.Biomass master contains volatile matter, and the thermogravimetric analysis result of stalk, rice husk is shown: volatile content is up to more than 60%~85%; It is good in the coal effect that these characteristics have determined that it not only has, and also determined the combustionproperty of catching fire that biomass are good.2. biomass fuel reduces discharging CO 2Benefit obvious, the benefit that reduces discharging sulphur is remarkable too.Biomass fuel has also that flying dust is few, deslagging is few, the NOx discharging is low, reduce also good environmental protection characteristic such as field of heavy metal contaminants discharging, lime-ash, can be referred to as green energy resource.3. because biomass material is cheap, the biomass molding fuel that produces also has bigger price advantage than present surging raw coal and moulded coal, is beneficial to and promotes the use of.4. biomass energy is a renewable energy source, and in today of energy worsening shortages, the development and use biomass energy also has great energy strategy meaning.
The core content of biomass energy technological development utilization is exactly the conversion using technology of the various biomass energies of research and development, realizes the cleanburning and efficient utilization of bioenergy.Wherein, biomass are compressed curing, make it be converted into the important method that higher-grade fuel is biomass utilization.At present, generally adopt the biomass granule fuel burning heat release of single component to carry out heat energy utilization both at home and abroad.West advanced country uses wood substance grain fuel substantially, and this is because this type of compressed moulding compact fuel, has the calorific value height, ash content is few and easy burning characteristics completely.But this type of granular fuel costs an arm and a leg in China, is difficult to and diffusing coal competition, promotes the use of difficulty.And a large amount of abandoneds of the byproduct-agricultural crop straw of China's agriculture production (especially maize straw) are unfortunately tangible.Maize straw utilizes in the process in burning, because the biomass ash fusion point is low, can make fouling of heating surface, wearing and tearing and generation corrosion and slagging scorification fusion, adversely affecting its combustion.This has become the key issue that development biomass energy combustion technology need solve.
Summary of the invention
A kind of compound bio matter granular fuel that the present invention relates to, it is molten to have solved the low ash of simple corn stalk pellets fuel, easily slagging scorification, key issue such as it is bad to burn.
The composition quality proportioning of compound bio matter granular fuel provided by the invention is:
Corn stalk powder: 70-75%,
Powdered rice hulls: 24-30%,
Calcium oxide powder: 0.5-1%.
Technical scheme of the present invention is earlier maize straw and rice husk to be carried out seasoning, or does behaviour's machine drying with hot blast, makes moisture less than 10%.Then maize straw, rice husk are ground into powder with pulverizer, add calcium oxide powder and uniform mixing by a certain percentage, utilize granule-forming machine to be crushed to the cylindrical particle fuel of diameter again for the 6-10 millimeter.At last granular fuel naturally cooling, screening and packing can be obtained finished product.
The invention enables this kind shaped fuel big area to promote, and can make peasant's revenue source variation, diversification, increase a large amount of job opportunities, alleviate the pressure that rural area residue population brings to society.This kind granular fuel can also be turned waste into wealth, and improves the whole people's environmental consciousness, helps the construction of conservation-minded society.The present invention meets the Energy policy and the environmental protection policy of country, and economic benefit and obvious social benefit have very vast market prospect.
