What is Stack?

Stack is nothing but chimney which is used to disperse the hot air at a great height, emissions & particulate matters that are emitted from the various types of stacks like boiler, flue gas etc. At these heights the polluted air disperse in a very large area so that concentrations at ground are within permissible limits and not harmful for humans, animals and vegetation.

There are several types of flue-gas stack based on fuel injections. Eg. DG set stack, flue gas stack, process stack, furnace stack, boiler stack, chimney etc.
