Device and method for high temperature corrosion test of supercritical material of crude oil burning boiler

Abstract

The invention relates to a device and a method for a high temperature corrosion test of a supercritical material of a crude oil burning boiler. The device comprises a flue mechanism, a combustion furnace, an oil supply pipeline mechanism and a gas supply pipeline mechanism, wherein the combustion furnace comprises a furnace body, a furnace cover, an oil groove and an oil nozzle; the flue mechanism comprises a high-temperature tubular stove, a sample hanging rack and a smoke linking pipe; the oil supply pipeline mechanism comprises an oil tank, an oil-pressing gas pipe and an oil supply pipe; and the gas supply pipeline mechanism comprises a gas supply pipe and a gas-pressing gas pipe. The test device provided by the invention is applied to the high temperature corrosion test of the supercritical material of the crude oil burning boiler; the crude oil is directly burned in the combustion furnace, and then the smoke after burning enters into the flue mechanism and the flue mechanism is specially used for controlling the smoke temperature; the test device provided by the invention is successfully applied to the laboratory investigation on the supercritical material; the data are true and reliable; the matching degree with the current data of industrial application of the enterprise is high; and the requirement of the enterprise on the forecasting for the high temperature corrosion performance of the supercritical material of the crude oil burning boiler is met.

Description

technical field [0001] The invention relates to the technical field of high-temperature test equipment, in particular to a high-temperature corrosion test device and method for supercritical materials of crude oil combustion boilers. Background technique [0002] At present, the world's power stations are mainly coal-fired power stations, oil-fired power stations, gas-fired power stations, nuclear power stations and hydropower stations. Japan, the Middle East, Russia, the western coastal area of ​​California, the central part of New England bordering the Atlantic Ocean, Florida, the southeastern and southwestern regions of the United States, and my country's coastal economically developed provinces use a large number of fuel-fired power stations. Since the Fukushima nuclear power plant leak in Japan in 2011, Japan has successively shut down all nuclear power plants and restarted fuel-fired power plants. Countries in the Middle East, such as Saudi Arabia, Iran, and Iraq, hav...
