This paper proposes the early stage Plan that Iron works and Refinery cooperate to save energy and to increase Co-production Blast Furnace process is originally Co-production process (Iron production & Gasification production) Excess fuels (asphalt & pulverized coal) injecting into Blast Furnace is gasified high-efficiently (95〜98%) At the early stage Plan, Excess fuels are asphalt 60kg/ton-pig iron and pulverized coal 65kg/ton-pig iron. This Blast Furnace Gasification System and BFG (Blast Furnace Gas) Combined Cycle Power System are optimized in a typical Iron works model (6mihon ton/Y steel product) with Pinch Technology method This Optimization yields Power (559MW) and surplus COG (Coke Oven Gas) that is exported to Refinery Energy saving 13% of total Iron works energy consumption is estimated.
