Claim:
1. An internal combustion burner comprising: a combustion chamber supplied with fuel and with oxidant, the chamber comprising a casing including a first end which is closed and with an opposite exhaust second end which is open and via which the combustion gases escape, the casing including at least two opposite walls connecting the two ends, and further comprising in the chamber and at the closed first end, at least two combustion devices supplied with oxidant and with fuel, the at least two combustion devices include a first type of combustion device and a second type of combustion device that are configured differently so as respectively to generate two distinct types of flame, and including a system for cooling the two opposite walls by introducing a cooling gas along the two opposite walls, wherein each combustion device includes a body having a first face facing an exterior of the combustion chamber at the first end and a second face opposite to the first face and facing an interior of the combustion chamber, the body including plural oxidant supply ducts and one fuel supply duct passing through a thickness of the body from one face to the other, with an axis of the fuel supply duct being perpendicular to the faces of the body, wherein the first type of combustion device and the second type of combustion device are arranged alternating in a ring on the first face of the body facing the exterior of the combustion chamber, wherein in a case of one of the combustion devices, the oxidant supply ducts are inclined with respect to the axis of the central fuel supply duct and each oxidant supply duct includes an inlet on the first face of the body of the device and an outlet opening onto the surface of the second face of the body of the device, the inlets and the outlets of the ducts being arranged in circles around the central fuel supply duct, wherein in the case of one of the combustion devices, a diameter of the circle of the plural inlets arranged around the central fuel supply duct have a same size as a diameter of the circle of the plural outlets arranged around the central fuel supply duct, and wherein, for each of the plural inlets and outlets, a diameter of the inlet is the same as a diameter of the corresponding outlet.
