Coke oven gas serves as a superior fuel compared to blast furnace gas because of its elevated________________?
Show answer Hide answer
Answer: D. All A., B. and C.
Explanation
Coke oven gas features a significantly higher calorific value compared to lean blast furnace gas. The clean burning nature of coke oven gas reduces maintenance requirements in sensitive heating applications. A low specific gravity results in a lighter gas, which substantially lowers pipeline distribution energy costs. Calorific value quantifies the total thermal energy released when a specific quantity of fuel is burned. Gas cleanliness refers to the minimal presence of dust, tar, and sulfur impurities in the fuel. Specific gravity dictates how easily a gas flows through distribution networks without excessive booster pressure.
Integrated steel plants utilize byproduct gases as valuable internal energy sources for various heating processes. Selecting superior fuel gases improves thermal efficiency and extends the operational lifespan of industrial furnaces. Optimizing fuel distribution economics is crucial for maintaining competitive manufacturing costs in heavy industry. Option A is correct but incomplete because it omits flame temperature and heat release rate advantages. Option B is correct but incomplete because it misses the calorific value and cleanliness benefits. Option C is correct but incomplete because it fails to mention calorific value and distribution economics.
