具有熱回收功能的蓄熱式熱氧化器(RTO)廣泛應用於各行業,透過去除有機污染物來控制空氣污染。然而,RTO 的一個顯著優勢在於其能夠回收大量能量,這些能量可用於各種製程。本文將探討如何計算熱回收功能的 RTO 的節能效果。
具有熱回收功能的RTO(反應式氧化器)是一種空氣污染控制系統,用於氧化廢氣流中的有機污染物。該系統由兩到三個填充有熱交換介質的陶瓷床組成。這些介質有助於從廢氣中回收熱量,並將其傳遞給進入的製程氣流。回收的熱量可用於各種工藝,例如預熱進入的製程空氣或水。
熱回收效率 帶有熱回收功能的RTO 是回收的熱能與廢氣中可用熱能的比值。影響熱回收效率的因素包括進出口溫度、廢氣和進入製程空氣的流量,以及氣體和空氣的比熱容。
熱回收效率可以透過多種方法計算,例如焓法、溫度法和有效性法。方法的選擇取決於可用數據和所需的精度。
熱回收功能的RTO的節能效果是指RTO消耗的能量與熱交換器回收的能量差。影響節能效果的因素包括進出口溫度、廢氣和進入製程空氣的流量,以及氣體和空氣的比熱容。
可以透過熱回收效率和廢氣中的熱能來計算節能效果。計算公式如下:
Energy Savings = (Heat Energy Available – Energy Consumed) x Heat Recovery Efficiency
我們考慮這樣一個案例:在一家製造工廠安裝了一台帶有熱回收功能的RTO(餘熱回收裝置)。該RTO消耗500 kW的能量,廢氣流量為10,000 Nm³。3/hr and an inlet temperature of 300°C. The incoming process air has a flow rate of 5,000 Nm3/hr and an inlet temperature of 25°C. The specific heat capacity of the gases and air is 0.24 kJ/Nm3°C and 1.005 kJ/Nm3°C, respectively.
利用焓值法,我們可以計算出熱回收效率為 84%。廢氣中可用的熱能為 2,232,000 kJ/hr。因此,採用熱回收的 RTO 可節省的能源為:
Energy Savings = (2,232,000 – 500,000) x 0.84 = 1,455,600 kJ/hr
這種能量可用於各種製程,例如預熱進入的空氣、節省能源成本和減少溫室氣體排放。
RTOs with heat recovery are an efficient way of controlling air pollution and recovering energy. Calculating the energy savings from RTOs with heat recovery is essential in determining the system’s efficiency and the potential cost savings. The calculation involves understanding the system’s components, calculating the heat recovery efficiency, and then calculating the energy savings. By understanding the calculation methods, one can optimize the RTO with heat recovery’s performance and enhance its benefits.
