Abstract

The invention provides to a combined type combustor with adjustable flame distribution. The combined type combustor comprises a mounting bottom plate, a combustor body, a fuel gas remixing plate, a corrugated spring plate, a combustion plate, a flame guide ring, a water inlet pipe and a water outlet pipe, wherein the upper surface of the mounting bottom plate is fixedly connected with the combustor body; a fuel gas inlet channel formed in the center of the combustor body extends downwards from a fuel gas inlet pipe mounting hole, and a water inlet pipe mounting hole and a water outlet pipe mounting hole are in threaded connection with a water inlet pipe and a water outlet pipe respectively; and a fuel gas remixing plate, a waveform spring plate, a combustion plate and a flame guide ring are sequentially arranged in a counter bore arranged at the top of the combustor body from bottom to top. According to the combined structure, the main body is connected in a threaded manner and is easyto machine and assemble; in addition, when any part, especially the top combustion plate is damaged, the damaged part can be replaced in time, the maintenance is more convenient, and the use cost isalso reduced.

Description

technical field [0001] The invention belongs to the technical field of gas heat load test devices, in particular to a combined burner with adjustable flame distribution. Background technique [0002] The gas thermal load test bench can be used for thermal fatigue test and assessment of engine cylinder head, piston and other heated parts. It uses the burner to repeatedly heat the test piece to simulate the thermal shock of the test piece during the working process. Performance and durability are particularly important, and they are the core components of the gas thermal load test bench. [0003] Most of the current burners are integrated and connected by welding or other means. During the heating process, the maximum temperature on the top surface of the burner can reach above 1000°C. During the cooling process or after the burner is stopped, the temperature of the burner will drop. Due to the change in temperature difference, a large thermal stress will be generated, which ...
