Fives designs natural gas and hydrogen firing solutions for the chloralkaline industry

A major local player in the chloralkaline industry chose Fives to provide a unique combustion solution capable of firing natural gas and hydrogen.


Located in the South of India, this industrial was looking to replace its current thermic fluid heating system with a new one.

Fives' recognition as an accomplished original equipment manufacturer (OEM) and its experience of successfully designing burners firing natural gas and hydrogen in this particular industry was key in winning this contract.

Indeed, since hydrogen burns very intensely and quickly with a low pressure available, the combustion solution must be remarkable as to ensure an efficient burning as well as meeting all safety requirements for this hazardous fuel.

Fives provided its client with an all-in-one thermic fluid heating system tailored to these requests. Aside from the thermic fluid heating system, Fives’ solution comprises of a burner and control system as well as an air preheater to attain a very high system efficiency in excess of 90%.

This combined combustion solution has also been designed to be energy efficient thus reducing the client’s energy consumption as well as its pollutant emissions.

Indeed, by using hydrogen and liquified natural gas as fuels, the burner enables the customer to comply with the NOx & CO (carbon) emission levels from the local Pollution Control Board.

Fives’ thermic fluid heating system has a heat capacity of 2.7 MW. It has a very compact design which includes radiant and a connective section to get a maximum heat transfer for a high system efficiency.
