Research On Energy Consumption System Analysis And Its Measures In China Erzhong

The manufacturing industry, especially heavy equipment manufacturing industry, is an important embodiment of country's industrial developing standard and international competitiveness. It is also a basic and strategic industry concerning long-term interests of nationality and nation. It is an extremely urgent task for manufacturing enterprise, especially for heavy equipment manufacturing enterprise that how to keep a foothold in domestic market demand, save resource, reduce energy consumption, reduce emissions, alleviate restraint of energy, release environmental pressure, take a new road to industrialization, take the clean and saving development road and form its own competition superority in advanced equipment manufacturing industry as soon as possible. In this paper, according to this demand, the energy consumption of the main production links and processes and key equipments in china erzhong are systemic analyzed and a number of countermeasures are proposed according to the existing problems afer the comprehensive understanding of energy conservation status and management model in domestic and foreign equipment manufacturing enterprises.Firstly, the energy conservation status in china erzhong is systemic analyzed focusing on the analysis of overall energy usage situation including the analysis of the energy input and energy consumption status, energy conversion production and energy consumption indicators calculation, analysis of the key processes' energy consumption (including steelmaking, forging, casting, heat treatment, welding, machining, etc.), energy production costs, integrated energy consumption indicators.Secondly, a number of countermeasures are proposed according to the existing problems of energy savings. The basic principles of enterprise energy-saving are put forward. Management measures and technical measures are mainly proposed. Management measures emphasis on enterprise energy management organization mode, enterprise energy management system construction, enterprise energy statistics management, enterprise energy consumption quota management and energy supply management etc. Technical measures focus on key process improvement, industrial stove transformation, boiler retrofit, the project of steam hammer to electro-hydraulic hammer, elimination of J Series Motors, promotion of frequency control technique and so on.Finally, General situation of energy-saving programme implementation in china erzhong is introduced focusing on two typical cases and its application (the transformation of the industrial gas furnace and the coal-fired boilers).
