Blast Furnace Excess Pressure Power Generation


Blast Furnace top Gas Recovery Turbine Unit£¨i.e.TRT£©takes advantange of the pressure energy and heat energy possessed by blast furnace top gas-secondary product in blast furnace process so that the coal gas does work by Turbine Expansion Engine to convert itself into mechanical energy¡£The energy drives the generator or other device¡£Now it is as a green product for energy conservation and emission reduction as what the CDM advocates¡£

¡¡¡¡The coal gas produced by the blast furnace enters the TRT by gravitational precipitator(Part of the process is circular seam)¡£It passes through speed control alve£¨parallel entrance electric butterfly alve£©£¬entrance slider damper£¬goes by gas flow meter¡¢fast cut alve£¬then it does work by turbine expanding to drive the generator into power generation¡£The coal gas from the turbine enters into low-pressure pipe network and parallels with reducing alve group of the coal gas system¡£¡¡

¡¡¡¡Generator outlet circuit breaker£¬which is connected to 10.5 or 6.3 KV system busbar,is linked to power grid through local substation.when TRT is running£¬generator transmits to the grid¡£While blast furnace damps down for short time£¬the generator makes electric-driven running without stepout¡£

¡¡¡¡TRT device consists of eight systems such as turbine host,large valve system£¬lubricating oil system£¬hydraulic oil system£¬water supply and drainage system£¬nitrogen sealing systems,high and low distribution system£¬automatic control system and two optional systems including corrosion scaleinhibition and remote online¡£
