The invention relates to the technical field of gas heating experiment devices, in particular to a combustion heater. The heater comprises a main combustion section shell, a main combustion section lining, a spray pipe shell and a spray pipe lining; the main combustion section shell detachably sleeves the exterior of the main combustion section lining, a gap is formed between the inner wall of themain combustion section shell and the outer wall of the main combustion section lining to form a first coolant channel, and a first sealing piece is arranged between the main combustion section shelland the main combustion section lining; and the spray pipe shell is connected with the main combustion section shell, the spray pipe lining is detachably arranged in the spray pipe shell, a gap is formed between the outer wall of the spray pipe lining and the inner wall of the spray pipe shell so that a coolant can pass through, and a second sealing piece is arranged between the spray pipe liningand the spray pipe shell. According to the heater, the coolant leakage can be prevented, and the spray pipe shell, the spray pipe lining, the main combustion section shell and the main combustion section lining can be conveniently replaced.
Description
technical field [0001] The invention relates to the technical field of gas heating experimental devices, in particular to a combustion heater. Background technique [0002] The combustion heater directly burns fuel to heat the gas, supplements oxygen, and uses nozzle acceleration to simulate the flow conditions of the actual flight of a hypersonic vehicle. Due to its compact structure, low test cost, short test period and long test time, the combustion heater can quickly heat the air to a high temperature, and is mainly used for scramjet free-jet and direct-connection test benches. [0003] For multi-component gas mixed combustion heaters, the temperature of the heating gas may reach 2000K or even higher, so even for a short time of several seconds, cooling design is required to protect the structure from ablation and damage. In order not to generate additional polluting gas, external cooling is generally adopted, that is, cooling channels are reasonably arranged on the out...
