Detection of flue gas emissions from heating furnaces
Thread Content
The heating furnaces in our several sets of equipment differ in terms of online monitoring of flue gas emissions, due to the different design approaches adopted by various design institutes. 1. There are two sets of devices for online monitoring of oxygen content, sulfur dioxide, nitrogen oxides, and carbon monoxide ； 2. The other sets of devices only have an oxygen content ； 3. Environmental regulations require that emissions of sulfur dioxide and nitrogen oxides in the atmosphere be within acceptable levels ； Let’s talk about your online monitoring project for the heating furnaces in your facilities – are there any cases of excessive emissions occurring on a regular basis?

It’s now the HSE department’s responsibility – they can’t focus only on safety; environmental protection is also important
In desulfurization units, CEMS is commonly used for online flue gas monitoring, but it is often inaccurate. Especially for nitrogen oxides, the level at the outlet is often higher than that at the inlet. Generally, online monitoring can provide an approximate indication of the flue gas conditions, but it is not particularly reliable
Low-nitrogen burners are said to be able to reduce nitrogen oxides in flue gas emissions, and we have chosen this type as well; however, their working principle is not yet fully understood. Those who have used them would be glad to share their insights!

Whether emissions exceed the limits has nothing to do with this CEMS; it mainly depends on whether the relevant equipment is in operation and on whether effective technical measures are taken to reduce emissions. It is understood that some facilities equipped with such systems do not operate due to high operating costs, so it is quite normal for emissions to exceed the allowed levels. These emission-reduction devices are only activated when inspections are conducted
