Clean Environ at Coal-based Industrial Sites

Of late the National Green Tribunal (NGT) has been in the news for pointing out numerous flaws in public activities including industries which result in serious environmental issues. Thus it has been instrumental in issuing strictures to be followed by all the stakeholders including the masses so as to ensure a cleaner environment and air to breathe.

 

The NGT has come down heavily on all establishments that have flouted prescribed norms, particularly those industries and others which belch out smoke and other pollutants into the atmosphere. Indeed, it is a Catch-22 situation since on the one hand we desire development on all fronts that entail massive core and infrastructure projects like power generation, steel production etc. and on the contrary also wish to have a cleaner environment.

 

However, one need not lose hopes since there are ways and means to check these oddities like thermal power plants where lot of fly ash and other wastes in the air do pose problems. To this end ash handling system manufacturers in India have risen to the occasion by designing and fabricating suitable modes to control the pollutants.

 

One of them is a Delhi NCR based company having facilities to design and fabricate these systems near Coimbatore in Tamil Nadu which have been commissioned at various thermal projects and mining sites across the country.

 

Incidentally, apart from being a leading turnkey EPC (engineering, procurement and construction) contracting agency this company is involved in the execution of material handling systems at various mining sites and their disposal yards of mined ore and other materials.

 

Thus it also figures also among the prominent stacker reclaimers manufacturers in India active at numerous projects in India and abroad too. With a commitment to the motto to keep the technology development dynamic, this company has emerged as a leading ash handling player in providing techno-commercially optimised and customised ash handling solutions at various thermal power, steel and cement plants among others.

 

In this exercise, it has proved its mettle with expertise in various modes of ash clearance and disposal such as:

·         Bottom Ash

·         Fly Ash

·         Recovery Water System

·         Mill Reject Handling System

 

Of course, it is well known as to how the reclaimed or recovered fly ash is used as the base material for bricks and tiles. Bottom ash is used in reinforcing concrete structures.

 

Thus with ‘two birds with one stone’ the environment is kept clean as well as the reclaimed waste is put into good use. In the Recovery Water System mode, the ash laden water is channelized to flow into a pond where over a specific period of time, the ash is allowed to settle down at the bottom while the water atop is recycled thoroughly to the extent of getting rid of even 2% ash particles.

 

Apart from this decantation, further hydrobin treatment of the water enables heavier particles to settle down at the bottom before recycling.

 

In addition to this process bottom ash is separated with the technique of multi-venturi cyclone manifold system. And the recycled water from this process is virtually free from all types of ash particles. The greatest advantage of this technique is that it does not require much space as such it is very economical in terms of capital and operational costs.
