Universal Blast Furnace Gas Expander Blast Furnace Gas Expander (BFGE) is intended to use excessive pressure of the blast furnace gas formed during the cast iron smelting in the blast furnaces of metallurgic plants. BFGE allows to generate the pollution-free electric power without burning of fuel gas. BFGE effectively uses the exhaust of the blast furnaces having various capacities: 1500, 1700, 1800 and 2000m3. It is possible to use BFGE with the furnaces of higher capacity (with partial use of the blast furnace gas or by using of two BFGEs). BFGE is implemented into technological scheme of metallurgic plant according to the diagram that follows: BFGE Main Technical Characteristics Parameter name Operating rate    maximum       nominal       Inlet gas pressure (excessive), MPa 0,20 0,16    BFGE discharge gas pressure (excessive), MPa 0,009    Gas flow (nominal), nm3/h 300 000 250 000    Inlet gas temperature, оС (without heating) +60 +50    Exhaust gas temperature, оС, not less than +5    Electric power (at ŋgen=0,97), kW, not less than 7 600 5 600    Shaft speed, rpm 3 000 BFGE Scope of Supply Turbo Expander Design Features.
