The influence of Heat-Pipe Waste Gas Recovery System and Energy Recycling System to Global Competition of Enregy Intensive Industries in Taiwan

Yao, David 03 July 2007 (has links)
The shortage of energy supply against growing demand globally has caused seriously impact to all industries, dead or alive, especially for the energy intensified industries, like oil refinery (Petroleum) Iron and Steel making industries which has been confronting tremendously with pressing concern for survival. Even both industries are within traditional industrial factor, but represent as key and fundamental industries as relied on, by all industries of a Nation. Therefore, all the international enterprises dealing with high-temperature production have been striving for long-term supply & steady quality of raw material of energy. Under this circumstance, the enterprises shall be offering to find the measures for cost-down of energy consumed, and further utilize the waste gas and heat as generated out of the production, that would surely produce the efficiency of energy, and not only diminish the dependence on primary energy, it also can effectively reach the goal of ¡§Independence of Energy¡¨ and optimization for the control of energy cost. This study is adopting the case study of Company ¡§C¡¨, with the analysis of SWOT, Five-force Analysis, and Diamond Model by Michael Porter, to further analyze the overall environment and circumstance of energy intensified industries. So that, it might help to understand further the strength and weakness of the energy intensified industries of our nation. First of all, to proceed the survey for the application of waste heat recovery system to energy intensified industries, and secondly, the application of waste heat recovery system to energy intensified industries in Taiwan, to generate direct and indirect efficiency whether or not to escalate the overall competitiveness to face the global competition. This research recognize the No. 1 pressure & bottle neck of the energy intensified industry lies mainly in the insufficiency of energy supply, and the upcoming environmental protection is getting more conscious & concerned. Therefore, all the industrialized countries have moved further forward to reinforce the energy saving technology, and increase the efficiency of energy using, developing new generation of energy with more efforts. Adoption of Company ¡§C¡¨, has recognized the following benefit, after the introduction of Waste Gas Heat Recovery System: 1. Recovery of Waste Gas of Hot Blast Stove, reduction of COG use, to transfer the saved COG to down-stream, to substitute the expensive natural gas, which is benefit to Company ¡§C¡¨ in the respect of energy saving. 2. Increasing the operation efficiency of hot blast stove, to have operation technique more Sophisticated, in the meantime, to eradicate the moisture out of BFG/Air and further extend the life time of ceramic burner of hot blast stove. 3. The Waste Gas Heat Recovery System has been totally mature with good reference of operation in the world market, which has been used by most steel mills in the world. There is actually no risk to adopt and apply this technology, & further carve out the good image of company ¡§C¡¨ in the respect of energy saving. 4. Reduction of SOx out of waste gas, and further diminish the temperature of waste gas released and can reduce the CO2 emission that is friendly to our environment. The research of this study recognized further, that energy intensified industry has been built up due to the scenario and situation of Taiwan in past few decades, in view of the development of economy, which is crucial industry & business sector. However, with the time running, the energy intensified industry requires to be adjusted for adaptation to the industrial environment of energy crisis and global warming. In this case, the largest potential worry for Taiwan is obviously insufficiency of energy supply. Furthermore, the technical level of energy saving of Taiwan is far more behind Japan, & many other European countries. General Speaking, the energy intensified industry of Taiwan is in weak situation at this moment. If Taiwan might introduce more advanced technology, and technical cooperation, technical research and development, or even training of qualified personnel enabling to upgrade the energy saving of Taiwan to be further upgraded for increasing the competitiveness of industries which is surely positive for a nation being more competitive. In view of energy intensified industry, shortage of energy supply and the price be kept high end, the recycling energy is not available within short time, for short and mid term, the best effective measures to solve the problem of energy is to reduce the amount of energy, for long run, it is great help to use the energy saving system to the energy intensified industry. For one hand, it might reduce the production cost; on the other hand, it can increase the energy operation efficiency. The heat pipe Waste Gas Heat Recovery System as described in this Study is well sound technology of energy saving.
