Incineration Technology

Dry scrubbing or a dry scrubber is a flue gas treatment proces which is international jargon for lime or SodiumBiCarbonate powder dosing with powdered activated carbon with a reaction chamber and a baghouse filter. The powder is creating a reaction in the reaction chamber with the flue gas pollluatants and the power is stopped by the baghouse filter. In this way the dust layer on the filter bags are also increasing the reaction possibility because of the "intense contact" of the powder layer on the dust filter.  

The feeling of calmness of operators in a control room is an important sign. They understand “the process”, and it is “under control”. Therefore, repetitive tasks like feeding waste, controlling the furnace, etc., are not their responsibility or task – that's the PLC operator's responsibility.

Outdoor set up of an incinerator is financially attractive. But the location and climate gives sometimes difficult evaluation to be done. And indoor is not always the best choice, but outdoor is also not always the best one. An evaluation needs to be made.

Renovations of old incinerators are not attractive jobs for designers and manufacturers, it is a site full of unexpected issues and a lot of time is spend, just to have a correct view on the actual situations before some works can be done, because:

Medical waste is always known as the "red bag" waste, but it is not everywhere in the world the same. What is the acids content of the medical waste in your country? Mainly the amount of Chlorine in the waste will decide a 1 stage or a 2 stage system. In Europe pharmaceutical companies have almost no Chlorine any more in the packaging. So the Chlorine will be about 0,5%. In most of Asian countries, the Chlorine is about 2% in the mass of the medical waste. A single stage can handle European medical waste, with intervention of the operator, which we discuss here.

A standard to compare different type of incinerators always apply to a specific type of waste and the price which need to be paid for consumables and for residues. Waste incinerators are mainly designed and sized on the basic charachteristics of waste :
