工业锅炉尾部余热回收常识有哪些

2018-03-07 05:47:13 PM

  工业锅炉对大家来说不是很熟悉,不知道工业锅炉的工作原理以及工作注意事项,今天我们大家就针对工业锅炉尾部余热回收常识有哪些给大家进行相关的解答。

  余热是在一定经济技术条件下,在能源利用设备中没有被利用的能源,包括高温废气余热、冷却介质余热、废汽废水余热、高温产品和炉渣余热、化学反应余热、可燃废气废液和废料余热以及高压流体余压等七种。

  根据调查,各行业的余热总资源约占其燃料消耗总量的17%~67%,可回收利用的余热资源约为余热总资源的60%.

  超导热管是热管余热回收装置的主要热传导元件,与普通的热交换器有着本质的不同。热管余热回收装置的换热效率可达98%以上,这是任何一种普通热交换器无法达到的。热管余热回收装置体积小,只是普通热交换器的13.

  常温清洁空气在鼓风机作用下,沿右边通道反方向流动冲刷热管,这时热管右边放热,将清洁空气加热,空气流经热管后温度升高。

  由若干根热管组成的余热回收装置,安装在锅炉烟口,将烟气中热量吸收并高速传导至另一端,使排烟温度降至接近露点而减少热量排放损失。加热后的清洁空气可烘干物料或补充到锅炉内循环使用。提高锅炉和工业窑炉的热效率,降低燃料消耗,达到节能的目的。希望这些知识能够帮助大家。

  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.
