A heat energy recovery installation installed on a beam reheating furnace equipped with burners includes a turbine that generates electricity by implementing a Rankine cycle on an organic fluid coming from calories derived partly from the fluid used for cooling the tubular beams via a first intermediate circuit, and in part from flue gases from the burners by way of a second intermediate circuit.

Method and facility for recovering thermal energy on a furnace with tubular side members and for converting same into electricity by means of a turbine producing the electricity by implementing a rankine cycle

Burner for an oven for reheating siderurlogical products such as billets, blooms or slabs, or for heat treatment oven, which is equipped with a fuel injection device and with an oxidant feed body feeding feed orifices with oxidant, the burner having an axial direction; the injection device is designed to provide a central injection of fuel via an orifice in, or parallel to, the axial direction of the burner; the oxidant feed body includes two sets of four oxidant feed orifices, each set including two orifices situated above a horizontal plane passing through the axial direction of the burner, and two orifices situated below this plane, the orifices of a second set being further away from the horizontal plane than those of the first set, the geometric axes of the orifices of the two sets making angles of inclination with respect to the axial direction of the burner.

Burner for a reheating furnace or heat treatment furnace for steel industry

A flat-flame burner for reheat, holding, and heat-treatment furnaces for treating iron and steel products. It has at least one fuel-injection pipe lying along the axis of the body of the burner, a combustion tunnel and a combustion-air feed, the air being distributed in and by the body. The fuel is introduced via the injection pipe or pipes through at least one axial orifice lying in a plane close to the external plane of the combustion tunnel, into the combustion products. This produces a first dilution of the fuel in these combustion products, the fuel/combustion products mixture thus obtained being diluted further in the combustion air.

Flat flame burners

A fluid-fuel burner of the type producing a flame with axial development, which includes a combustion tile, having a broad shape, provided with an oxidizer and fuel injection orifices. These are approximately parallel to the major axis of symmetry of the tile, the internal shape of the latter as well as the orientation of the fuel and oxidizer injection orifices being chosen so as to create a difference in the distribution of the combustion products and of the recycled flue gases. A spread out flame is produced which ensures homogeneous distribution of the heat flux.
