The invention concerns a system for energy and environmental optimisation of a facility comprising at least one combustion apparatus (1) with a burner (3). The system comprises an electrolyser (2) and an injection system (4) connected to at least one fuel (3a) and/or oxidant (3b) inlet of the burner (3). The injection system is capable of injecting, at such an inlet, gases from the electrolyser (2) and/or a mixture of these gases and a combustible fluid and/or an oxidising fluid. The electrolyser (2) and/or the injection system (2) are controlled on the basis of at least one piece of information originating from the combustion apparatus (1) and/or sensors (6x) of the installation. The electrolyser can comprise a heat exchanger (2a) for cooling the device and/or preheating the water (EP) that is intended to then be heated (EC) by the combustion apparatus (1).

The present disclosure seeks to provide a metallic burner tile for use in industrial processes such as cracking. The tile is substantially metallic (e.g. more than 80%) with the balance being ceramic coating on surfaces exposed to high temperature. The tile is lighter and more durable than the current ceramic burners.

A cutting nozzle for a gas torch, such as a postmixed oxy-fuel gas torch, comprising a body with a torch end adapted to engage the gas torch, a discharge end, and a peripheral surface between the torch end and the discharge end. The body has a plurality of bores for respectively conducting fuel gas, preheat oxygen and cutting oxygen through the nozzle, each of the plurality of bores extending from the torch end and terminating in a respective discharge orifice at the discharge end of the body. A set of the plurality of bores are preheat oxygen bores connected to an oxygen source at the torch end for discharging the preheat oxygen at the discharge end. A plurality of air bores each have an inlet orifice located on the peripheral surface of the body and open to an air source, and a discharge orifice in or proximal to the discharge end.
