Residual Heat Analysis Of Submerged Furnace And SPSS Energy Saving

In china90%of ferroalloy is produced by the submerged arc furnace method, which consumes more energy and high material consumptions, so it is highly valued by government in energy-saving and emession reduction. The utilization of submerged arc furnace waste heat and the analysis of SPSS saving has impressed theoretical significance and bright future.We need measure the temperature of smoke, flow rate, composition and calculate the calorific value and exergy value.For submerged arc furnace flue and flow testing, the temperature presented fluctuations and erregular cyclical changes during operation. The energy value and the energy value that the submerged arc furnace smoke recycls are regarded the standard of evaluating the quality and quantity of gas waste heat. We use the thermal energy analysis and port value analysis to calculate the energy value and the energy value that can be recycled in the process of production, all that must be guided by the first and second laws of thermodynamics.18MVA submerged arc furnace high temperature flue gas heat can recycle2.58mw energy value, and the smoke can recycle1.10MW.The analysis of the recycling potential of smoke and flue gas and water residue produced all the year round. According to the research of the annual production that submerged arc furnace procuces, we established the material, energy balance model to analyze the material and energy of the submerged arc furnace. The chart of energy balance shows that the gas take away8.41MJ. Solid waste on the submerged arc furnace waste heat resources, using recyclable energy, exergy value and the level of solid waste heat resources to evaluate the situation. The enthalpy per ton of waste can be recycled submerged arc furnace is1.60GJ/t. According to the annual output of waste heat recovery is able to calculate the waste. The level coefficient of waste is0.701for high-quality waste heat recovery potential. At the same time the paper analyzes and compares the treatment and recovery method of solid waste ferroalloy way home and abroad, China’s ferroalloy slag treatment could be improved.According to the analysis and energy level matching analysis submerged arc furnace waste heat utilization, energy level power coefficient and the coefficient of heat energy level of resources compared to larger energy gap. Used for power generation, energy use does not comply with the matching principle. From the level of theoretical analysis, waste heat production and temperature of116℃, the steam pressure is0.127MPa reasonable. submerged arc furnace production process due to the huge energy consumption, power characteristics facilitate transmission, cogeneration is the main choice. In this paper, high-temperature waste heat utilization coefficient of thermal waste heat power generation and cogeneration, power generation efficiency and energy saving aspects were analyzed. This article describes the different types of submerged arc furnace flue gas waste heat power generation technology program. Finally, high-carbon ferromanganese, for example, for the production of high carbon ferromanganese current consumption, high energy consumption problem by SPSS software to analyze production. Taking a ferroalloy plant submerged arc furnace production data for the object. Production systems modeling, manganese recoveries obtained as the dependent variable, grade manganese ore into the furnace as the independent variable exponential regression model. Thus the actual operation of a guiding role.
