#Submerge arc furnace generatorTherefore, the gas generator set needs to monitor the occurrence of knock-through sensors to adjust the operating state of the unit. Its methane number (MN) is only about 60% of that of natural gas, which means that this gas is more prone to knock in the cylinder of the internal combustion engine. The antiknock property of fof is also significantly different from that of natural gas. The calorific value of fof is usually only about 1/3 of that of natural gas, that is, compared with natural gas models with the same output power, the air intake of fof generator sets needs to be increased by more than 3 times. Combustion Characteristics and Utilization Difficulties of 2 Submerged Arc Furnace Tail Gas In the past, the tail gas of submerged arc furnaces was usually discharged after direct combustion, but now it can be generated by the efficient gas-fired internal combustion engine, and the heat energy of high-temperature flue gas can be used to make efficient and full use of energy.Ģ. If the reducing agent contains volatile hydrocarbons, hydrogen (H2) will be formed. Carbon monoxide (CO) gas is formed due to the presence of carbon in the reducing agent. The off-gas (fof) produced in the process of ferroalloy production in submerged arc furnaces is mainly composed of CO and a small amount of H2, CO2, etc. The tail gas produced by the closed furnace contains more combustible components and can be used for gas internal combustion engine power generation. The submerged arc furnace is mainly divided into two types: semi-closed furnace and closed furnace. It is mainly used for reducing smelting ore, carbonaceous reductant, solvent, and other raw materials, and mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon manganese alloy, and other ferroalloys. Source of Tail Gas from Submerged Arc FurnacesĪ submerged arc furnace is also called an electric arc furnace or resistance furnace.
