工業鍋爐產品重要分為兩種,一種是蒸汽,主要是用于發電的,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。具體使用工業鍋爐生產時需要注意什么呢?下面就為大家做詳細的介紹。
鍋爐生產時需要降低鍋爐排煙溫度,因為鍋爐排煙是熱損失的一項,排煙量的大小主要取決于排煙溫度的高低,所以降低排煙溫度是提高鍋爐熱效率的重要一項措施。在使用過程中要避免熱面上有結渣或者積灰的情況,
如果遇到灰塵比較多,需要定期吹灰,對于松散的積灰可定期用吹灰的方法清除,如果附著在管子上的時間比較長,就會變得越來越厚。因為積灰會生產粘結性的硫酸鹽和亞硫酸鹽等,時間長了不容易清洗,吹灰的介質可以選擇過熱蒸汽、壓縮空氣和惰性氣體等。
另外還要投入一定量的鍋爐清灰劑,鍋爐在燃燒運行時需要投入一定量的清灰劑,進入爐膛之后會生化分解,爐受熱面的結焦、結渣接觸并滲透到受熱面,發生微爆反應分解高溫結渣,使其分解、脫落,可減少和防止煙垢的生成。
工業鍋爐生產中要增加或者改進尾面受熱面,因此要增加鍋爐的金屬耗量和煙氣的流動阻力,遇到含硫高的燃料時,排煙的溫度要保持高一些。合理的排煙溫度須從金屬與燃料的比價,運行維修費用的增加等方面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.
