Some thoughts on electrical energy conservation
Thread Content
Industrial enterprises are major consumers of energy in China, accounting for about 70% of the country’s total energy consumption. Among them, the nine key energy-consuming industries – steel, non-ferrous metals, coal, electricity, petroleum and petrochemicals, chemicals, building materials, textiles, and papermaking – account for over 60% of total industrial electricity consumption. Yet their average energy intensity is 40% higher than that of the world’s most advanced countries. As China’s market economy continues to mature, most domestic enterprises are facing increasingly fierce competition in a globalized market, and many of them are confronted with the problem of declining profits. To address this, they must focus on expanding their market presence and strengthening cost control. Among the various costs of Chinese industrial enterprises, electricity costs have become the third or fourth largest cost, right after material costs and labor costs; in particular, for some energy-intensive enterprises, electricity costs are the most significant expense. Moreover, most electrical devices operate with excessive capacity, meaning there is significant potential for energy savings. It has become essential to reduce costs and increase profit margins by saving electricity. Let’s discuss our ideas and approaches to energy conservation. Personally, I think there are many energy-saving products available in the country, but few specific solutions; at present, there is a lack of an overall energy-saving strategy.
The truth is quite simple. . Many energy-saving device technologies are quite advanced. . There are many overly advanced things that factories won’t use; in fact, they simply can’t use them. . Ah, just expressing an exclamation. . The staff is too large; it’s inefficient
Currently, people’s understanding of energy-saving technologies remains superficial; they are focused on the technical aspects and lack systematic solutions. True innovation comes from innovations in the manufacturing process!
China’s level of energy utilization is relatively low; in other words, the energy consumption per unit of GDP is high. It will take time to change this situation, and the main approach is to further improve production efficiency and energy utilization rates. This requires the efforts of many people, and possibly several generations
Many of today’s energy-saving products are based on theoretical calculations, and it’s hard to believe them in practice; however, I do believe in energy savings in the field of lighting.
Energy conservation is a good topic. But this thing can’t be achieved overnight either. It involves many things. Such as manufacturing processes, theoretical knowledge, practical experience, leadership support, willingness to take risks, system stability issues, and so on. Remember **'s speech. Let everyone be able to benefit from the achievements of technological progress. Think carefully about this sentence; P
A combination of management-based energy savings and technical energy savings.
For electrical energy savings, companies should start by focusing on off-peak electricity usage, as this constitutes the largest portion of energy consumption. Next is the peak load charge, which is the maximum demand. Finally, there is the power factor compensation fee returned by the electric utility company. It is obvious that the method of charging electricity fees and their prices are the most effective economic levers for achieving success in electrical energy conservation at this stage. Companies that invest heavily in purely technical aspects, see slow returns, and have frequent leadership changes generally do not consider short-term factors. If our predecessors do not plant trees, future generations will have nothing to shade under. But this is the reality of our country; without regulatory constraints and improved systems, energy-saving efforts can only remain mere showmanship. :(This post was last edited by WantYourLife3000 on 2009-4-5 at 02:09.)
Only wealthy factories invest in energy conservation. After all, energy conservation requires the purchase of energy-saving devices, and those devices are expensive...
When the process cannot be changed, inefficient motors should be phased out, and variable frequency drives should be used for pumps and fans with frequent load changes. The compressor and refrigerant are under centralized control, with a logical start/stop mechanism properly established.
