Briquetting lines BRISUR 200, 400, 600, 800, 1000

BRISUR briquetting lines are manufactured with 20 years of BRIKLIS experience.

They are designed for medium to large plants with multi-shift operation.

The BRISUR technological line consists of the BUS sawdust drier including boiler for its heating, one or more briquetting presses BrikStar, and rotary stand for bagging the briquettes. The plant can be delivered as a complete system including design of its layout in a production building with requirements for building conversions, full assembly i.e. assembly and connection of individual pieces of equipment, electric installation from the control panel of the switchboard, debugging of the entire line including its putting into test operation and operator training. Neither the delivery nor installation include power lead to electric switchboards.


Description of technology:

The feed screw is able to bring material from the sawdust pile onto the conveyors. Wet sawdust is separated by the vibrating screen situated above the wet material tank. Coarse pieces fall through the screen in the container, and can be put in the boiler manually. The drum sawdust drier is heated with flue gases from the boiler designed for automated combustion of wood waste. Sawdust feed to the drier is regulated by the control system in such a way that the output temperature of the steam from the drier is maintained at a constant value. The control system also regulates the fuel supply in the boiler. Flue gases from the boiler are cooled with cold air to a temperature of 300 to 500o C and are drawn by the fan in the drier. The fan is situated downstream of the drier on the cyclone separator of dust. Dry sawdust is taken from the drier by the screw conveyor which serves as a turnstile. Further the sawdust is transported by the screw conveyor to the receiving hopper of the briquetting press. The briquettes fall from the exit pipe of the press to the bagging place.

Parts of the BRISUR briquetting line

  • Material preparation
  • Material entry
  • Drying drum
  • Boiler room
  • Air handling system
  • Material exit
  • Control and regulation
  • Briquetting


Material preparation

 Crushers must be used for preparation of a material whose dimensions exceed the permitted size of 15 mm. Briquettes cannot be produced from only the crushed material without addition of sawdust. The share of sawdust should be at least 50%. Appropriate crusher shall be installed according to the specific material. Knife chipper for long pieces of wood, hammer mill for straw, or crusher with one low-speed rotor for lump waste. The crusher shall always be equipped with a screen with hole diameter smaller than 15 mm. The power input of the crusher depends on hourly output as well as on material properties. Power inputs of the crushers may vary from 15 kW to 50 kW.

Metal separator is usually a less frequent part of the technological line. Its installation is recommended in particular in processing a material of unknown origin. The magnetic separator very efficiently eliminates crusher damage by metal objects.

Material entry

Feed screw is installed in the material store, mostly under a shed. The feed screw brings the material from the brought pile of sawdust to the conveyor which supplies the screen upstream of the drier hopper. The centre of rotation of the screw is over the conveyor hopper. Semi-circular movement of the screw is controlled by the sensors which monitor the material level in the hoppers of the conveyor and the drier. The operator fill the material in the stated space in front of the feed screw. When the pile is finished, the screw can be returned to the initial position, or it is possible to turn the screw shield manually, and to use the screw in reverse direction.

Vibrating screen with round holes is used for the separation of big pieces of bark or wood from the sawdust. The canted screen in the steel frame is hooked on springs. The vibratory motor moves the screen so that the material is spread in a thin layer on the screen. Big pieces unsuitable for drying  slip down the screen into the furnished container for sorted waste. Small-sized material falls through the screen directly in the hopper of the drier or on another conveyor.

Conveyors of belt type are used for transport of unsorted material. Downstream of the sawdust screen the material is mostly transported by screw conveyors.  Their advantage is dust-free operation.

Drying drum

BUS drum sawdust drier is a set of devices that form one functional unit – a drying drum, feed and discharge hoppers of the drier, boiler, cyclone separator, fan, connecting piping and a switchboard with the drier control system.

Drying drum is a steel welded single shell heat insulated cylinder, whose front side is connected to the receiving hopper of the drier and supply of hot flue gases, and rear side closed by the material discharge hopper with extracting screws. The drum dimensions, diameter and length, vary depending on capacity. The advantage of the single-shell design is big saving of electric power, because the material is transported through the drier only by rotation of the canted drum. The drier works continually. Sawdust dosing in the drier and fuel feeding in the boiler is controlled by the control system. Dry sawdust is taken from the drier by the screw conveyor which serves as a turnstile into the briquetting press dry material tank. Thanks to its design, the drier works in a very economical mode, because it is heated by the flue gases from the boiler for combustion of wooden waste.

Boiler room

Boiler burns off wood on a fixed grate. Three-chamber design of the boiler with a domed combustion chamber ensure high efficiency and quality of combustion. The boiler brickwork is from refractory bricks. Optimum fuel is wood chips of length smaller than 20 mm and moisture up to 30%. The boiler hopper can be automatically replenished by a screw conveyor from the drier hopper. Flue gases from the boiler are cooled with cold air to a temperature of 300 to 500°C and are drawn into the drier by the fan for the fume exhaust.

Air handling system        

Exhaust fan is installed at the end of the air duct, and transport steam from the drier to the stack. In the entire drier including the boiler there is a small underpressure, which eliminates leak of combustion gases from the process to the space of the operator. The drying air takes fine wood dust out of the drier. The dust is separated in the two-stage cyclone separator. Emissions of solid pollutants meet the requirements of the air protection standard.

Material exit

Screw conveyors are used for the transport of dry material to the hoppers of the briquetting presses. Individual briquetting presses are connected to the conveyor by a pipe that goes through the cover of the hopper. The conveyor system is designed so that it enables the discharge of excess material in a furnished container.

Control and regulation

Control of moisture of the dried material is indirect; outlet material moisture is not measured. Moisture is regulated by dispensing the material into the drier in such a way that the outgoing steam temperature is maintained at a constant value set by the drier operators.

Drier operation consists in monitoring proper run of individual devices, setting required temperatures of the inlet and outlet temperature controllers, replenishing material on the material pile, monitoring the material level in the hoppers of the drier, boiler and briquetting press. Some of the activities can be automated, nevertheless continuous supervision is necessary. Another duty of the operator is minor maintenance consisting in removing caught objects on the transport routes, lubricating prescribed points by grease, removing ash and sand arising from wood combustion from the boiler.
Briquetting

Briquetting presses BrikStar 200, 300, 400

Briquetting presses BrikStar MAGNUM

 

The number of the installed BrikStar briquetting presses depends on the required output of the line. Material is continually transported by the screw conveyor from the sawdust drier to the press receiving hopper.

The briquettes fall from the exit pipe of the press in the PE bags in the rotary stand or in high-capacity bales. The closing of the bags is only carried out after evaporation of residual moisture. The briquettes can be combusted in all types of stoves, boilers and incinerators for combustion of solid fuels. Their high heating value of 15 to 18 MJ/kg is better used in gasifying boilers. The line can be equipped with the BrikStar briquetting presses with various types of dies – cylindrical dies of diameter 55 mm, angular dies 55 x 55 x approx. 60 mm, and angular dies 135 x 65 x approx. 90 mm.

 

Safety of operation

The entire technological line meets the requirements of safety standards. For certification purposes a risk assessment report has been prepared, and the right to issue CE declaration of conformity has been verified.  Research Institute seated in Radvanice has performed measurement from the viewpoint of explosion and fire hazard, and the State Fire Protection Administration has issued their approval for the operation of the line.

For safe operation is however necessary to follow strictly the instructions for operation of the technological line with attention to work discipline of the operators. It is forbidden to dry materials with big difference in moistures in the drier. High temperature of the drying air that is necessary for intensive drying of the moist material can cause ignition of part of the material that enters the drier almost dry. The drum of the drier and the separators can be equipped with nozzles for supply of fire water.
