Directing heated and cooled air where it is needed and recycling heat to save energy
Whether using the straight grate process or adding a rotary kiln to make the grate-kiln process, our products are key to the process. To dry and heat the ore pellets, a number of fans are used to recycle heat from the kiln. After indurating in the kiln, cooling fans are used to cool the pellets for handling downstream, and fans are used to facilitate dust handling.
Every Howden product is backed by an absolute commitment to lifetime support and service that covers all spare parts, troubleshooting, scheduled maintenance and emergency response. We are dedicated to maintaining your plant at peak performance and, above all, keeping it in continuous production.
Some of today's most arduous applications for Howden products are found in the iron and steel industry. The need to move large volumes of air or gas, in many cases at high pressures and high dust burdens, places stringent demands on the mechanical design of the impeller.
Our fans are highly efficient designs, reducing power consumption in an energy intensive industry, while operating in high temperature and erosive environments. Our extensive experience in each application enables us to provide equipment of great reliability with the consequent reduction of unplanned outages.
The preheating fan is recycling heat from waste gases from the kiln to heat up the pellets.
This fan will dry the pellets by recycling waste gases from the heating process and force the waste gases through a dust removal system.
This fan utilizes heat from the cooling process for the first drying stage of the pellets and forces the waste gases through a dust removal system.
Cooling fans supply ambient air to cool the pellets for downstream material handling.
This fan supplies heated combustion air by recycling heat from the traveling grate.
This induced draught fan draws dust from the process through a dust removal system and releases the cleaned gases to the atmosphere.
To collect the waste gases and draw them through a dust collection system before releasing the cleaned gases to the atmosphere.
Our lifelong aftercare service will supply original replacement parts, support you with maintenance and installation, and even train your own engineers in maintenance techniques. We keep detailed plant records almost indefinitely, and regularly supply spare parts for machinery over 50 years old.
