Embodiment
[0038] First put the alloy sample used in the experiment into the quartz tube 7 and seal it with a flange sealing plate, then open the oxygen cylinder 2 and the nitrogen cylinder 1, adjust the first flow meter 3-1 to 55%, and adjust the second flow rate Adjust the meter 3-2 to 30%, then turn on the water bath 4, and adjust to the target temperature of 55°C according to the experimental requirements. The oxygen provided by the oxygen bottle 2 and the nitrogen provided by the nitrogen bottle 1 are mixed through the two ports of the T-shaped tee. Gas, the mixed gas passes into the first gas washing bottle 5-1 placed in the water bath 4 through the third port of the T-shaped tee, and mixes with the deionized water in the first gas washing bottle 5-1 , at the target temperature of 55°C, the mixed gas will carry water vapor with a specific humidity, and enter the first end of the quartz tube 7 through the first gas outlet conduit 8-1, and the surface of the alloy sample in the quartz...

Description
technical field [0001] The invention relates to the field of material high temperature resistance and corrosion resistance experimental equipment, in particular to an experimental device for simulating the high temperature corrosion environment of biomass and detecting experimental reaction gas in real time. Background technique [0002] High-temperature biomass corrosion is a common phenomenon in biomass power plants today, and it is also the main reason that affects the service life of biomass power plant boilers. In order to improve the service life of boilers in biomass power plants and thus improve the benefits of power plants, corrosion tests in high-temperature corrosion environments for biomass have been extensively studied. The mechanism of high-temperature corrosion of biomass is various, so it is necessary to conduct as many experiments as possible to find the source of corrosion; at the same time, in order to find ways to reduce and prevent corrosion, it is also ...
