Abstract

The invention discloses a device and a method for measuring fine power amount and tar amount in high-temperature gas. The device consists of a gas sampling unit, a gas-solid separation unit and a gas-liquid separation unit. A method for measuring fine powder amount and tar amount in high-temperature gas consists of steps of gas back flushing, preheating, secondary gas back flushing, sampling, device stopping, and measurement of fine powder amount and tar amount. According to the device and the method, the powder amount and the tar amount in high-temperature gas can be measured effectively, the design of a gas-solid separation system and a gas-liquid separation system can be precisely guided, and the safely and stably continuous production of a gasification furnace, a coking furnace and a semi coke furnace can be realized.
