A method for the production of particle-like bio-coke for use in reduction in the context of an environment-friendly production of ferroalloys, whereby bio-coke with sufficient strength, low ash, sulphur and phosphorus content, as well as low volatiles content, is produced continuously from biomass raw material, the method comprising the following steps: a) lifting of tree stumps, dividing them into pieces and shaking off impurities; b) storing and pre-drying them at the lifting site; c) storing, pre-drying, pre-cleaning and pre-comminuting them at the roadside; d) de-icing the stump material, comminuting it into particle-like form; e) transporting the ground stump material by a vibrating conveyor screen to a storage silo; f) drying the stump material; g) carbonizing the dried stump material in a carbonization reactor, where a first part of the gases and dust formed in carbonization of the biomass raw material is burned in the carbonization reactor with an air deficit; h) feeding a second part of the gases formed in the carbonization of the biomass raw material to a post-combustion boiler, in which they are burned and the thermal energy that is generated is utilized to produce electricity and district heat and the cooled circulation gas is conveyed to the drying and carbonization of the particle-like biomass raw material; i) conveying the particle-like bio-coke formed in carbonization to cooling and conveying the cooling medium used either to the carbonization reactor or to the post-combustion boiler; j) screening the cooled particle-like bio-coke formed in carbonization and conveying to briquetting, a first step of which is grinding; k) mixing the fine particle-like bio-coke with water and a binding agent thus regulating the strength of the bio-coke; l) pressing the bio-coke mixture into briquettes; m) drying the briquettes. a) lifting of tree stumps, dividing them into pieces and shaking off impurities; b) storing and pre-drying them at the lifting site; c) storing, pre-drying, pre-cleaning and pre-comminuting them at the roadside; d) de-icing the stump material, comminuting it into particle-like form; e) transporting the ground stump material by a vibrating conveyor screen to a storage silo; f) drying the stump material; g) carbonizing the dried stump material in a carbonization reactor, where a first part of the gases and dust formed in carbonization of the biomass raw material is burned in the carbonization reactor with an air deficit; h) feeding a second part of the gases formed in the carbonization of the biomass raw material to a post-combustion boiler, in which they are burned and the thermal energy that is generated is utilized to produce electricity and district heat and the cooled circulation gas is conveyed to the drying and carbonization of the particle-like biomass raw material; i) conveying the particle-like bio-coke formed in carbonization to cooling and conveying the cooling medium used either to the carbonization reactor or to the post-combustion boiler; j) screening the cooled particle-like bio-coke formed in carbonization and conveying to briquetting, a first step of which is grinding; k) mixing the fine particle-like bio-coke with water and a binding agent thus regulating the strength of the bio-coke; l) pressing the bio-coke mixture into briquettes; m) drying the briquettes.
