popup.description1

To develop a new technology of thermochemical conversion of biomass, the main difference of which from existing installations is to obtain at the outlet of the installation two generator gases of different calorific value and composition (low-caloric and medium-caloric) with a low resin content with full fuel conversion.

According to the main objectives of the project to develop scientific and technical conditions and technical documentation for the creation of a transportable energy complex for the production of electricity and heat from local fuel, numerical models of aerodynamics, heat and mass transfer and chemical reaction were developed, which describe the working process in the gasifier and pyrolyzer of the thermochemical biomass processing plant. The results of numerical studies allowed us to develop an original design of a pyrolysis-gasification plant in one device. The numerical studies of the biomass heating process in the pyrolyzer allowed us to simulate the process of heat transfer of hot synthesis gas through a metal pipe to a stationary porous body with biomass characteristics, which showed that in 4500 s such a porous body will heat up to a temperature close to the synthesis gas temperature. Mathematical modeling of the process of cooling from 700 to 80 °C and cleaning of fine dust from hot synthesis gas in a wet Venturi scrubber was carried out. The results showed high efficiency of the processes at a specific water loss of 5.71 kg/nm3 of synthesis gas. Based on the results of numerical studies, working design documentation for an experimental biomass pyrolysis-gasification plant was developed. A set of design documentation necessary for the construction of a pilot plant with an electric power of 5 kW was prepared and the upper part of the pyrolysis-gasification plant with a pyrolysis chamber was manufactured.
