Travelling grates pre-heaters

Because of the cyclic change of temperature, travelling grate components are very specific products which require a lot of attention.

The constraints to which these components are exposed differ form one item to the other one. For instance:

  • Priorities for the grates and side plates will be to resist to thermal shocks, thermal fatigue and chemical attacks, ….
  • Priorities for the chain links and sprockets will be to offer best mechanical resistance for the whole span of temperature met, ….

High dimensional accuracy is a must to maintain a perfect alignment of the grate and secure the right clearance between the various parts.

Today’s focus on alternative/waste fuels really deserves special care when deciding on the alloys selection.

Magotteaux can assist you at any stage of your project from the supply all the way to the turn key project including supervision and supply.
