Method and the system for stream gassing of solid power fuel, preferably hard coal, brown coal and biomass

摘要

Method and installation for the flow of solid energy, in particular coal, lignite and biomass, meeting energy efficiency requirements above 90%,reducing the cost of producing electricity and heat means that the energy gases constituting the main component of the gasification mixture are produced outside a low temperature stream reactor (RG) in a cyclone kiln (PC) to which the coke residue obtained is produced as a result of discharges in the discharge cyclones (C1),(C2) obtained air gas having a chemical composition of 50% -55% nitrogen N2, 25% -28% carbon monoxide CO, 10% -12% hydrogen H2, 3,5% -4,5% carbon dioxide, 4% --6% hydrogen vapour H2O. The coke residue collected in the reservoir (ZK) is passed through a lock (S) controlled by a computer control system (KUS) to a cyclone burner (PC). The low-temperature reactor is powered by a fuel-gas mixture from an energy mill (M),at which the carbon dosed by the dosing device (D) is fed,controlled by a computer control system (KUS).
