High temperature and high pressure isolation valve; the air compression mechanism is communicated with the compressed air buffer tank through the first high-pressure insulation pipeline, and the compressed air buffer tank is connected to the ignition hole of the combustion type air heater through the second high-pressure insulation pipeline; the inner wall or outer wall of the compressed air buffer tank is provided with There is a high temperature resistant insulation layer; the compressed air buffer tank is provided with a high temperature and high pressure air release valve; the first and second high temperature and high pressure isolation valves and the inner wall of the high temperature and high pressure air release valve are provided with a high temperature heat insulation layer.

Description

Technical field [0001] The present invention is the field of stamping engine test, which involves a high -temperature compressed air ignition device, which specifically involves a ignition method for a combustible air heater with high temperature compressed air ignition device and combustion air heater. Background technique [0002] In order to study the flying process of the stamping engine at a high altitude, the test air heating system needs to be established to simulate the high 焓 in the state of flying. For the ground test of the stamping engine, whether it is a free shooting or direct connection test, the air heater is one of its key equipment. The combustion air heater can ensure long -term stable work, but the combustion air heater requires external energy to start. Therefore, a reliable and simple ignition device is a prerequisite for the burning air heater to work normally, and also makes the ignition device of the heater the key component of the stamping engine test pl...
