回归主流:以“能源价值”为核心的目标体系宝钢原有的四级能源管理指标体系以能源平衡为基础,在进行节能减排和能源成本管理时遇到瓶颈:不能体现各种能源介质价值量的差异、未能涵盖影响能源成本的所有因素,无法满足能源精细化的要求,也无法体现能源管理全员、全方位、全流程的特性。以工序能耗指标为例,某一工序消耗的所有能源介质,无论其成本高低都按折算系数折算成标准煤。折算系数由能源介质本身特性决定,与价格无关。比如某一加热炉用1kg标准煤热值的天然气和高炉煤气,如不考虑燃烧效率差异,其能耗指
Back to the Mainstream: Target System centered on “Energy Value ” Baosteel’s original four-level energy management indicator system is based on the energy balance and encounters bottlenecks in energy conservation, emission reduction and energy cost management: it can not reflect various energy sources The differences in the value of media can not cover all the factors that affect the cost of energy, can not meet the requirements of energy refinement, and can not reflect the full, all-round and full flow of energy management. Take the process energy consumption index as an example, all the energy media consumed by a certain process are converted into standard coal according to the conversion coefficient regardless of the cost level. The conversion factor is determined by the nature of the energy medium and has nothing to do with the price. Such as a furnace with 1kg of standard coal calorific value of natural gas and blast furnace gas, if you do not consider differences in combustion efficiency, energy consumption refers to
