Hydrogen-rich exhaust blending ratio
Thread Content
What are the typical composition components and calorific value of hydrogen-rich exhaust gas? In coke ovens heated with coke oven gas, what is the typical percentage range in which hydrogen-rich off-gas is mixed in? For blast furnace gas and heated coke ovens, what is the typical percentage range in which hydrogen-rich off-gases are blended in?
1. The composition and calorific value of hydrogen-rich exhaust gases vary depending on the production process; they generally contain hydrogen, carbon monoxide, methane, etc., with a calorific value typically ranging from 8,000 to 12,000 kcal per cubic meter. 2. Coke ovens heated with coke oven gas typically have a hydrogen-rich off-gas mixture proportion controlled within the range of 5-15%. 3. The proportion of hydrogen-rich off-gas mixed into coke ovens using blast furnace gas for heating is generally kept within the range of 5-10%. .
