9.Hydrocarbon An organic compound that contains carbon and hydrogen only, e.g. acetylene, butane. Many of the components of natural gas, petroleum, and coal are hydrocarbons.
10.Main reasons are: production of hot DRI (HYTEMP system ), optimization on gasifier size and operation mode, use of low-grade fuels (heayy residuals, orimulsions, petroleum coke or coal) with on influence on DRI quality, uniform steel qualities, minimum environmental impact, etc.
