Problems solved by technology

When the evaporated water contains organic dry distillation products, the application of this method becomes problematic due to environmental unfriendliness such as strong odor
Furthermore, the known devices do not allow to utilize in an efficient manner the different process streams, side flows and undesired intermediate / end products in the process

Embodiment Construction

[0054] figure 1 Presented is an apparatus according to the invention for producing pyrolysis products comprising: a combustion boiler for generating heat energy, i.e. a fluidization boiler 1; a fast pyrolysis reactor for forming pyrolysis steam, i.e. a pyrolyzer 2; condensing unit 3 for condensing pyrolysis vapors; and separate fuel feed units 5 and 6 for supplying feedstock to the combustion boiler and pyrolyzer. Furthermore, the plant comprises a cyclone separator 4 for separating the solids and heat transfer medium from the pyrolysis vapor after the pyrolyzer 2 . The fluidization boiler, pyrolyzer, condensing unit and cyclone separator are combined in the manner presented in the figure. The pyrolyzer is integrated in connection with the fluidization boiler.

[0055] Most of the fuel, such as carbon, peat, lignite or oil shale, is supplied to the fluidized boiler 1 through the feed device 5 . Furthermore, the feeding device 5 is arranged to supply smaller quantities of tr...

Abstract

The invention relates to an apparatus for producing a pyrolysis product, the apparatus comprising a pyrolysis reactor (2) for forming pyrolysis product fractions from raw material by fast pyrolysis, a condensing device (3) for condensing gaseous pyrolysis product fractions to mainly liquid pyrolysis product fractions, a combustion boiler (1) arranged in conjunction with the pyrolysis reactor for forming energy fractions, and feeding devices (5, 6, 22) for feeding raw materials to the pyrolysis reactor and the combustion boiler. According to the invention, the apparatus comprises a separating device (4) arranged substantially in conjunction with the pyrolysis reactor for separating other fractions (13) from the gaseous pyrolysis product fractions after the pyrolysis and means (13) for conducting other fractions than the gaseous pyrolysis product fractions from the separator (4) to the combustion boiler (1).

Description

technical field [0001] The invention relates to a plant for the production of pyrolysis products as defined in the preamble of claim 1, said plant comprising: a pyrolysis reactor for forming a pyrolysis product fraction from a feedstock by rapid pyrolysis, for converting gaseous pyrolysis products Condensation plant for condensing fractions into mainly liquid pyrolysis product fractions, combustion boiler for forming the energy section - pyrolysis reactor is arranged in connection with the combustion boiler, and for feeding raw materials to the pyrolysis reactor and combustion Boiler feeding device. Background technique [0002] It is known from the prior art that pyrolysis products, i.e. pyrolysis liquid or pyrolysis gas, are produced from different kinds of biomass or organic materials, such as wood, bark, paper, straw, waste plastics, oil, etc. Shale, lignite, peat, etc. Pyrolysis is typically performed at temperatures of about 300°C to 800°C under anaerobic conditions....
