Abstract
The present invention discloses a kind of compound biomass fuel and its production process. The compound biomass fuel consists of biomass fuel in 5-70 wt%, coal fuel and sulfur fixing agent. The production process includes the steps of: crushing biomass fuel into biomass fuel powder, crushing sulfur fixing agent into sulfur fixing agent powder, crushing coal into coal powder, mixing the three kinds of powder to form mixture, adding water to regulate humidity of the mixture, forming and drying to form the compound biomass fuel. The compound biomass fuel has fast igniting, powerful fire power, complete burning, less dust and high heat utilizing rate, and is suitable for use in various kinds one boiler.
Description
Technical field
What the present invention proposed is fuel field biomass composite fuel and manufacture method thereof.
Background technology
Before the present invention proposes, in order to improve the combustionproperty of coal slime and broken coal, usually broken coal is pulverized the back and be pressed into coal briquette by briquetting press, this coal briquette helps transportation and burning is used, when in burner commonly used, burning, be difficult for making unburned ickings to drop, and help ventilating, help transportation and keeping.But exist shortcoming to be: because machine is when pressing coal briquette, coal briquette center density height, in the incendiary process oxygen supply insufficient, combustionvelocity is slow, forms black core easily.
Honeycomb briquette is the system type form of producing coal that produces after coal briquette, by pushing, coal dust is combined with binding agent make bulk, and bore a hole on the type piece, is beneficial to ventilation oxygen supply when the combustion chamber.This moulded coal burn application in the moulded coal stove and accessory of special use that suits has sufficient combustion, is easy to transfer the advantage of fire.Existing shortcoming is: it is low to make efficient, and consumed power is big, and transportation difficulty, and cracky are not suitable for a large amount of storages and keeping.
For fluidizing furnace, liquefied bed, the employed coal of coal-powder boiler all is Powdered, normally directly makes coal dust by coal pulverizer in the burn application place, seldom transports.Pulverized coal fuel can be realized abundant burning, the heat utilization ratio height of fuel.Existing shortcoming is, owing to for auxiliary facility requirement condition height such as powder, ventilation, slagging-off, only be applicable on the special-purpose burning boiler and use, is not suitable for using on the small-sized civilian or burner that complementary conditions are low.
At present, because mineralizing stone energy extraction cost improves and the minimizing of disposable fossil energy, acting as a fuel to utilize with biomass energies such as agricultural crop straw, agricultural product castoff, Forest products processing waste, organic wastes has become the focus that society is concerned about, associated fuel processing, the improvement of combustion unit constantly develops.But with regard to biomass energy, normally it is made particle, employing machinery or manually method of supplying burning utilization in commonly used or special combustion unit of different size or shape by compression method.The existing shortcoming of biomass energy particle is: raw material is collected difficulty, and tooling cost height, transportation and keeping are difficult.
According to the data introduction, the biomass energy source material combines the ignition quality and the physical and chemical index that can improve both sides with coal, can realize the relative merits complementation.Method in common is coal and biomass material powder separated pulverizing to be mixed or mix the back pulverize mixing.Normally directly with Powdered supplied burner tool burn application, existing shortcoming is this compound fuel: the storage of raw material, processing and the transportation and the service requirements strictness of burning, and have certain scale using value and economic worth are just arranged.
Summary of the invention
The present invention is directed to the existing shortcoming of present biomass fuel, coal and composition thereof fuel, propose a kind of biomass composite fuel manufacture method.This method can realize that biomass fuel and coal fuel are compound, thereby improves its processing, storage, combustionproperty, reaches the technique effect of energy-saving and environmental protection and economic and suitable widespread usage.
The applied technical scheme of technical solution problem of the present invention is:
1, constitute biomass composite fuel by biomass fuel, coal fuel and sulphur-fixing agent mixing, wherein biomass fuel weight accounts for 5～70% of biomass composite fuel weight.
2, the biomass composite fuel manufacturing processed is: make biomass fuel be crushed into powder by biomass fuel pulverizing process 1; Make sulphur-fixing agent be crushed into powder by sulphur-fixing agent pulverizing process 2; By the broken operation 3 of coal dust coal dust is broken into and is powder; By mixing agitating procedure 4 biomass fuel, sulphur-fixing agent and coal are mixed, form mixture; Adjust the humidity of mixture by adding water conservancy project preface 5; Make mixture form desired structural shape by molding procedure 6, become the finished product compound fuel after the drying.
Beneficial effect:
Adopt the made compound fuel of the inventive method, combine the advantage of biomass fuel and coal fuel, have on fire soon, firepower is violent, sufficient combustion, and dust is few, the heat utilization ratio height, the intensity height is easy to transportation and keeping, and suitable various industry and civil boiler use.
