Energy & Waste Heat Recovery from Incinerators

Incinerators not only burn wastes and bring them down to negligible sterile ash, they can also recover heat energy generated during the process.  Wastes that are incinerated could be municipal solid waste, hazardous industrial waste, biomedical waste or any other.  These could be in the form of liquid, solid or gas.

 

Today incinerators burn wastes of every kind including nuclear waste.  They also recover precious metals which would otherwise be lost in a mass of catalytic carriers.  These precious metals could be in the form of gold, silver, palladium, etc. which takes millions of years to transform to their present form.  Some of these precious metals are also recovered from jewellery manufacture where fine dust particles are lost in PPE, floor sweepings, etc.

 

There was a negative connotation, until sometime back, that using incinerators cause environmental damage.  This is not true in these days of improved designs and advancement in technology, where if one considers nuclear waste incineration, dust particles of not more than 1 mg/m3 in flue gas are released.  Imagine a speck of dust in 1000 litres of gas!  

 

From time immemorial, we have been using fire to burn things down.  Any fuel that is used produces heat energy, whether it is cooking or driving or running a plant.  Haat has embarked on a program of saving energy released after combustion.  This has resulted in culmination of projects where waste heat recovery boilers are connected midstream of the configuration of equipment resulting in production of steam which can be used for various purposes. 

 

When one considers the ROI of such a plant, the cost can be recovered very quickly indeed! Apart from the latest designs meeting environmental norms, such a decision makes business sense also.  The incinerator thus is no longer used only for destroying the unwanted trash, but also works as a production equipment by earning money and by-products for the user.

 

Haat is happy to announce they are in the process of executing projects of this nature where the user is benefitted by waste heat recovery and have even extended recovery mechanisms to include recovery of acids from flue gas scrubbers. 

 

Haat’s new age designs are also available to other industries who have a need.
