Numerical studies on thermochemical processing of peat in a fixed layer

Purpose. To investigate the gasification process of peat in gas generators with a fixed bed at pressure 1.5 MPa and create initial conditions entrance to waste burners required for combustion binary mixture. Methodology. The objects research were granules Volyn peat. calculate gas, constructed model thermochemical processing solid fuel, described first part work by authors was used. Findings. It is shown that area close upper boundary bed, where stationary, there jump temperature particles from 300 772C, which tar practically not released, thus obtained pyrolysis contains CO2, H2O, H2 CO. structural physicochemical characteristics are discharge chamber furnace steam generator TPP-210A formed. Originality. when velocity decreases, slag formed between zone maximum heat release grate, consists cooled ash particles, protect grate overheating. With such an organization it possible achieve stationary mechanical incompletely burned material equal zero. Practical value. help fuels adjust height dry distillation changing dispersed phase rate heterogeneous homogeneous chemical reactions proportion O2 or H2O air enrichment.
