Product composition control and temperature control is possible. Scrap iron and iron ore can be directly converted to steel. No iron is lost as slag, since air is not directly passed through the molten metal. The regenerative system of heat economy ensures fuel saving. The steel got i..

Unlike solid fuels liquids and gaseous fuels leave behind no ash. They have low ignition temperature compared to solid fuels. The calorific value of liquid and gaseous fuels is higher and can be easily transported through pipelines. They also produce very little smok..
