Abstract: The present invention relates to a combustion heater (100) for providing controlled heat (H) to an endothermic reaction process. The combustion heater comprises an integrated burner (20) to yield a hot burner exhaust gas (35) flow from burning a first fuel. The burner exhaust gas mixed with oxidant flows to a flue gas outlet along a flue gas flow path (FGP). Provided to the combustion chamber at a position outside a direct reach of flames from the burner is a secondary fuel conduit (30) with a plurality of nozzles (31) from which a second fuel (32) is transferred into a flow along the said flue gas flow path (FGP). The resulting combustion of the second fuel can be used to provide controlled heat to the to endothermic reaction operated in a reaction conduit (40) that is in thermal heat exchange with the combustion chamber.
