玻璃與化工、鋼鐵、水泥、火力發(fā)電以及陶瓷一樣，是高能耗、高污染產(chǎn)業(yè)。大量的能量消耗，不僅帶來(lái)非�？膳碌沫h(huán)境污染問(wèn)題，同時(shí)也導(dǎo)致企業(yè)生產(chǎn)成本居高不下，使企業(yè)舉步維艱。燃料消耗是玻璃企業(yè)非常大的一塊成本，即使是管理的玻璃企業(yè)，也要占玻璃生產(chǎn)成本的40～50%，普通企業(yè)甚至高達(dá)60%。因此，節(jié)能降耗不僅是社會(huì)問(wèn)題，也是企業(yè)能否得以生存的關(guān)鍵所在。
十幾年來(lái)，我公司在進(jìn)行玻璃技術(shù)服務(wù)的同時(shí)，在玻璃窯爐節(jié)能方面也進(jìn)行了大量的嘗試和不懈地努力，并成功開(kāi)發(fā)了一系列投入資金省、能耗低、有效果快的節(jié)能型玻璃窯爐，并獲得多項(xiàng)國(guó)家發(fā)明專(zhuān)利。該節(jié)能型玻璃窯爐拋開(kāi)了傳統(tǒng)玻璃窯爐設(shè)計(jì)理念，從玻璃窯爐內(nèi)部運(yùn)行規(guī)律入手，采用獨(dú)特的結(jié)構(gòu)形式和實(shí)際的操作理念，使玻璃窯爐的節(jié)能降耗達(dá)到了一個(gè)新高度。這種窯爐不僅節(jié)約能源，減少污染，同時(shí)大大地減少了玻璃窯爐的建設(shè)費(fèi)用。通過(guò)近幾年在浮法、光伏以及微晶玻璃生產(chǎn)線的實(shí)際運(yùn)用，得以逐步完善和提高，技術(shù)日趨成熟，已達(dá)到非常理想的效果。浮法玻璃每公斤玻璃液實(shí)際單耗已降至1200kcal，超白玻璃較傳統(tǒng)窯型節(jié)能約40%(250噸級(jí)生產(chǎn)線每天消耗天然氣5萬(wàn)立方米，成品率高達(dá)82%)，同時(shí)在玻璃的質(zhì)量和生產(chǎn)穩(wěn)定性方面也得到大幅提高。
Similar to those for chemical engineering, steel, cementing, thermal power and ceramics, the industry for glass is also well-known for its high-energy consumption and high-pollution, which brings us with the very frightening problems of environmental contamination, simultaneously, results in the production cost at such a higher level that the company has to confront with difficulties for daily managing. Fuel consumption is usually the largest cost for a glass company, occupying about 40-50% production cost for those with excellent management; it could also be even approaching 60% for a common company. As a result, energy-saving and consumption-reducing is not only a social problem, but also the key factor essential for company’ s survival.
In the last two decades, our company has paid great efforts on the research for energy-saving glass furnace while offering the glass technical service, and has successfully developed a series of energy-saving furnace with particular advantages including economical investment, low energy consumption and fast profit returns, and now several national patents have already been authorized regarding to the inventions on the glass furnace technology. Away from the traditional idea for glass furnace design, the energy-saving one employs the unique architecture modes and practical operating ideas on the basis of its inner working law, leading to the energy-saving of glass furnace arrived at a higher summit. Moreover, this one can save energy consumption, decrease pollutions and significantly reduce the construction fee of the glass furnace. Over a few years of the practical application of the production lines for the floating, photovoltaic and microcrystal glass industries, the latest energy-saving furnace technology has been gradually optimized, improved, and matured; accordingly, the practical application effect has already been extraordinarily ideal. The cost for floating glass has been decreased to 1200kcal/kg glass liquid, about 40% energy saved as compared with the traditional super-clear glass furnace (50,000 m3 natural gas was daily consumed for a 250 tons production line with 82% of the finished product rate), and the quality and production stability of glass is capable of dramatically enhanced.
