Analysis On Energy Consumption And Its Influencing Factors Of Shougang Jingtang Iron And Steel Enterprise

The iron and steel enterprises are the big butts of resources consumption and also the large family of environment pollution, and their old operation mode, which means "high input, high consumption, high pollution", should be changed. They should save energy, reduce product costs and enhance resource utilization efficiency, and produce not only various diversification but also environmentally friendly high quality steel and iron products by advanced production technology.The principle of Shougang Jingtang iron and steel enterprises is "reduce, reuse and recycling", and its characteristic is "low consumption, low emissions and high efficiency". It will improve waste utilization cycle to generate zero emissions. And it will become demonstrative base of circular economy in China"s steel industry.This paper describes the current situation of energy consumption for iron and steel enterprise in China and the developing stage and trend of systems energy conservation, and the energy-saving level was compared and analyzed between China and foreign advanced enterprises. The energy consumption model of iron and steel enterprise are reviewed.Shougang Jingtang iron and steel enterprise is the object of this disseration. The reality production status is connected with energy consumption, and analyzing on the influence of energy consumption with advanced production technology. The input-output model of energy consumption analysis of iron and steel enterprise is erected. And a example are calculated using this model to analyze the product energy value, the unit process energy and current situation of energy consumption of Shougang Jingtang iron and steel enterprises. The influence of factory layout, material to steel ratio, product structure, advanced production technology, external factor on energy consumption are calculated and analyzed. The calculation example indicates:(1) Reasonable factory layout is helpful to reduce its transportation energy consumption, decrease loss of heat, improve product rate and reduce environmental contamination.(2) Ore to steel ratio and iron to steel ratio decrease the same degree. The influence of ore to steel ratio on energy intensity per ton is less than iron to steel ratio.(3) The lord process product structure has a certain effect on energy intensity per ton.(4) In these advanced production technologies, using the sea water desalination technology will lead to increase energy intensity per ton. And using CDQ technology greatest reduce energy intensity per ton in other four energy saving technologies.(5) National policy and product prices have a significant influence on energy consumption.
