在现代制药工业的生产过程中，不可避免地要使用大量的化学与生物制剂，这带来的一个结果是在生产的每个步骤都会排放出成分复杂的尾气，以挥发性有机化合物(VOC)居多。如何处理含VOC的尾气，成为企业面临的一大环保难题。国内目前主要采用热氧化法的处理方式，即蓄热式热力焚化炉(英文名为“Regenerative Thermal Oxidizer”，简称为“RTO”)
二、RTO工作原理
把有机废气加热到760摄氏度以上，使废气中的VOC在氧化分解成二氧化碳和水。废气首先通过蓄热体加热到接近热氧化温度，而后进入燃烧室进行热氧化，氧化后的气体温度升高，有机物基本上转化成二氧化碳和水。净化后的气体，经过另一蓄热体，温度下降，达到排放标准后排放。不同蓄热体之间通过切换阀，随时间进行转换，分别进行吸热和放热。氧化产生的高温气体流经特制的陶瓷蓄热体，使陶瓷体升温而“蓄热”，此“蓄热”用于预热后续进入的有机废气，从而节省废气升温的燃料消耗。陶瓷蓄热体应分成两个(含两个)以上的区或室，每个蓄热室依次经历蓄热-放热-清扫等程序，周而复始，连续工作。蓄热室“放热”后应立即通过反吹风机对该蓄热室进行清扫(以保证VOC去除率在95%以上)，只有待清扫完成后才能进入“蓄热”程序。RTO设备的工作流程见下图：
三、控制要求和方法
3.1. 燃烧器控制
氧化室安装一个带比例调节的天然气燃烧器。燃烧器的供热量是用氧化室温度，经过PID调节器自动调节，当燃烧器运行时，燃烧器PID的SP外给定值(TE05_AM)等于SP外给定值+升温速率设定值/120。按照升温曲线进行升温。否则，SP外给定值等于氧化室温度。如果SP外给定值超过TE05_S10(氧化室温度--理想控制温度设定)，那么TE05_S10直接赋值给TE05_AM(SP外给定值)，进行温度限制。此外，燃烧系统还带有熄火保护、超温报警和超温自动停燃烧器等功能。
3.2.进气、出气、清扫流程的切换
该设备有三个蓄热室，一个公共氧化室，有机废气通过鼓风机送入蓄热室1，吸热后进入氧化室，蓄热室1因放热而降温，燃烧升温后的气体进入蓄热室2，通过热交换把热量蓄存在蓄热室2的陶瓷蓄热体中，处理后的气体经后续处理合格后烟囱排空。同时蓄热室3空间中残留未处理的VOC废气被反吹风机吹回氧化室焚化处理。经过一段时间(约2分钟(可设定))后，气流改变方向从蓄热室2进入氧化室，通过蓄热室2吸收热量升温后，在氧化室内高温焚化，最后经蓄热室3热交换后排放，同时蓄热室1处于清扫状态，经过一段时间(约2分钟(可设定))后，气流再次改变方向，不断的交替循环，保证氧化室温度在800℃以上，以此保证高的去除率和换热效率。程序如下图：
