工業鍋爐(lú)對大家來說不是很熟悉,不知道工業鍋爐的(de)工作原理以及工作注意事項,今天我們(men)大家就(jiù)針對工(gōng)業鍋(guō)爐尾部餘熱回收常識有哪些給大家進(jìn)行相關的解答。
餘熱是在一定經(jīng)濟技術條(tiáo)件(jiàn)下,在能源利用設備中沒有被利用的能(néng)源,包括高(gāo)溫廢(fèi)氣餘熱、冷卻介(jiè)質(zhì)餘熱、廢汽(qì)廢水餘熱、高溫產品和爐渣餘熱、化學(xué)反應餘熱、可燃廢氣廢液和廢料餘熱以及高(gāo)壓流體餘壓(yā)等七種。
根據調查,各行業的餘熱總資源(yuán)約占其燃料消耗總量的17%~67%,可回收利(lì)用的餘熱資源約為(wéi)餘熱總資源的60%.
超導熱(rè)管是熱管餘熱回收裝置的主要熱傳導元件,與普通的熱交換器有著本質的不同。熱管餘熱回收裝置(zhì)的換熱效率(lǜ)可達(dá)98%以上(shàng),這是任何一種普通熱交(jiāo)換器無法達到的。熱管餘熱回收裝置體積小,隻是普通熱交換器的13.
常溫清潔空(kōng)氣在鼓風機作用下(xià),沿右邊通(tōng)道反(fǎn)方向流動衝刷熱管,這時熱管右邊放熱,將清潔空(kōng)氣加熱,空氣(qì)流經熱管後溫度升(shēng)高。
由若幹根熱管組成的餘熱回收裝置,安裝在鍋爐(lú)煙口,將煙氣中(zhōng)熱量吸收(shōu)並高速傳導至另(lìng)一端(duān),使排煙溫度降至接近露點而減少熱量排放損失。加熱後的清潔空氣可烘幹(gàn)物料或補(bǔ)充到鍋爐內循環使用。提高鍋爐和工業窯爐的熱效率,降低燃料消耗(hào),達到節能的目的(de)。希望這些知識能夠幫助大家(jiā)。
Industrial boilers are not very familiar to everyone, do not know the working principle of industrial boilers and work matters needing attention, and today we all for the industrial boiler tail waste heat recovery common sense which to give you relevant answers.
Waste heat is energy that is not utilized in energy utilization equipment under certain economic and technological conditions, including waste heat of high temperature exhaust gas, waste heat of cooling medium, waste heat of waste steam waste water, waste heat of high temperature products and slag, residual heat of chemical reaction, waste liquid and waste of combustible waste gas Waste heat and high-pressure fluid pressure and other seven.
According to the survey, the total waste heat in various industries accounts for about 17% to 67% of the total fuel consumption, and the waste heat recovery and utilization resources account for about 60% of the total waste heat resources.
The superconducting heat pipe is the main heat conduction element of the heat pipe waste heat recovery device, which is essentially different from the ordinary heat exchanger. Heat pipe heat recovery unit heat exchange efficiency up to 98%, which is any ordinary heat exchanger can not be achieved. The heat pipe waste heat recovery device has a small volume, and is only an ordinary heat exchanger.
Clean air at room temperature under the action of the blower, flow along the right channel flow counter-flow erosion heat pipe, then the right heat pipe heat, the clean air heating, air temperature after the heat pipe.
The waste heat recovery device consists of several heat pipes installed in the boiler mouth to absorb the heat in the flue gas and conduct the high-speed heat to the other end to reduce the flue gas temperature close to the dew point to reduce the heat emission loss. The heated clean air can dry the material or be added to the boiler for recycling. Improve the thermal efficiency of boilers and industrial kilns, reduce fuel consumption, and achieve energy savings. Hope this knowledge can help everyone.
