工業鍋爐(lú)產品重要分為兩種,一種是蒸汽(qì),主要(yào)是用於發電的,一種是供電的,以煤為原料,這就是比較常見的工業鍋爐類型。具體(tǐ)使用工業鍋爐生(shēng)產時需要(yào)注意什麽呢?下麵(miàn)就為大家做詳細的介(jiè)紹。
鍋爐生產時需要降低(dī)鍋爐排煙溫(wēn)度,因為鍋爐排煙是熱損失的一項,排煙量的大小主(zhǔ)要取決於排煙溫度的高低,所以降低排煙溫度(dù)是提高(gāo)鍋(guō)爐熱效率的重要一項措施。在使用過(guò)程中要避免熱麵(miàn)上有結渣或者積(jī)灰的情(qíng)況,
如果遇到灰(huī)塵比較多,需(xū)要定期吹灰,對於鬆散的積灰可定期用吹灰(huī)的方法清除,如果附(fù)著在管子上的時間比較長,就會(huì)變得越來越厚(hòu)。因(yīn)為積灰(huī)會生產粘結性(xìng)的硫酸鹽和亞硫酸鹽等,時間長了不容易清(qīng)洗,吹灰(huī)的介質可以選擇過熱(rè)蒸汽、壓縮(suō)空氣和惰性氣體等。
另(lìng)外還要投(tóu)入一定量的鍋爐清灰劑(jì),鍋爐在燃燒(shāo)運(yùn)行時需要投入一定量的清(qīng)灰(huī)劑,進入爐膛之後會生化分解,爐(lú)受熱麵的結焦、結渣接觸並滲透到受熱麵,發生微爆(bào)反應分解高溫結渣,使其分解、脫(tuō)落,可減少和防止煙垢的生成。
工業鍋(guō)爐生產中要增加或者改進尾麵受熱麵,因此要增加鍋爐(lú)的金屬耗量和煙氣的流動阻力,遇到含硫高(gāo)的燃料時,排煙的溫度要(yào)保持高一些。合理的排煙(yān)溫度須(xū)從金屬與(yǔ)燃料的比價,運行維修費用(yòng)的增加(jiā)等方麵(miàn)進行技術經濟比較來確定。
Industrial boiler products are mainly divided into two types, one is steam, which is mainly used for power generation, the other is power supply, using coal as raw material, which is a relatively common industrial boiler type. What should I pay attention to when using the industrial boiler? Here's a detailed introduction for everyone.
Boiler production needs to reduce the boiler exhaust temperature, because the boiler exhaust heat is the largest one, the amount of exhaust depends mainly on the level of exhaust gas temperature, so reducing the exhaust gas temperature is to improve the thermal efficiency of the boiler an important measure . In the use of the process to avoid slag or dust on the hot surface,
If you encounter more dust, the need for regular soot, for loose dust can be regularly used soot removal method, if attached to the pipe for a long time, it will become thicker and thicker. Since dust deposits produce cohesive sulphates and sulfites, it is not easy to clean for a long time, and soot blowing media can be selected from superheated steam, compressed air and inert gas.
In addition, a certain amount of boiler cleaning agent needs to be put into operation. When the boiler is operating in combustion mode, a certain amount of cleaning agent needs to be put into the furnace. After entering the furnace, it will be biochemically decomposed, and the coking and slagging of the heating surface of the furnace come into contact with and infiltrate the heated surface. The explosive reaction decomposes the high-temperature slag to make it decompose and fall off, which can reduce and prevent the formation of soot.
Industrial boiler production to increase or improve the heating surface at the end, so to increase the boiler metal consumption and flue gas flow resistance, met the high sulfur fuel, the exhaust gas temperature to be kept higher. Reasonable exhaust gas temperature must be determined from the technical and economic comparison between the ratio of metal to fuel and the increase of operating and maintenance costs.
