Problems solved by technology

The problem arises through conveying that so-called inclusions form on the same material, for example fine inclusions next to coarse inclusions in biomass
In the planning of large-scale industrial production, the following problems also arise: when expanding the twin-roller press or the roller press, the supplied screw conveyor must be enlarged by an excessive factor to achieve orderly charging, or Multiple screw conveyors must be set up in parallel for large granulation presses
However, multistage gravity separation or other separation methods also have the following disadvantages: these separations do not have 100% efficiency, but in the case of large-scale industrial use and large flow of biomass per hour (greater than 15 tons / hour) Always keep sand or other dense material in the biomass
In the plant part after separation, i.e. in the biomass silo or afterward, impurities can also enter the production process through wear or abrasion of the plant part, which can lead to damage to the pelletizing press

Embodiment Construction

[0019] according to figure 1 , to describe the production process of pellets according to the prior art as follows. The pretreated and screened biomass 1 is placed and discharged into a biomass silo 3 . This can be done with an intermediate conveyor or directly with the dosing unit 4, according to figure 1 , the dosing device 4 is configured as a dosing screw conveyor 19 . According to requirements, the biomass 1 can be treated with steam by means of a steam treatment device 13 in the metering screw conveyor 19, or if necessary, can also be checked in an intermediate station for defective parts of the biomass, which are produced for granulation. Definition of hazardous impurities for presses. In the discharge area, the biomass falls off a metering screw conveyor 19 and is now pressed into pellets 9 in this example with a pelletizing press 2 comprising two rollers.

Abstract

A method and an installation for producing pellets from prepared biomass in a pelleting press for use as fuel in fireplaces. The biomass is made of fibers, shavings or chippings containing cellulose and / or lignocellulose, with or without a binding agent and / or additives, and after being prepared is stored in a biomass bunker. The method includes: biomass discharged from the biomass bunker into a scatter device, a mat made of the biomass having a substantially uniform weight per unit area formed by the scatter device on a molding belt, the mat produced on the molding belt examined by an examining device for defective spots and / or foreign substances, and the mat supplied to a pelleting press. At least parts of the mat or a section of the mat include defective regions and / or foreign substances separated from the method upstream of the pelleting press.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for the production of pellets from pretreated biomass in a pelletizing press for use as fuel in a furnace. Furthermore, the invention relates to an apparatus according to the preamble of claim 12 for producing pellets from pretreated biomass in a pelletizing press for use as fuel in a furnace. Background technique [0002] It has been known for a long time to produce pellets (also called compacts or pellets) from fine material or compacted and / or melted material. A briquette press compacts material between two rollers, one or both of which are made as a female mold, and shapes the material into a briquette for combustion. Pelletization by means of extruders and perforated plates (if applicable with subsequent cutting devices) is also sufficiently known in the plastics industry or the animal feed processing industry. The production of pellets from preferably comminuted biomass (eg ...
