Abstract

The invention discloses a measurement device for residual carbon quantity in fly ash. The device comprises a sampling unit, a measurement unit and a control unit, wherein the sampling unit is connected with an ash collecting device in the measurement unit through an ash collecting pipe; in the measurement unit, four crucibles are uniformly arranged on a rotating device along the circumference, the ash collecting device, a burning device and an ash discharge device are respectively arranged above the crucibles, a weighing device is arranged below the crucibles, an ejector rob is arranged on an elevating device, the ash collecting device, the ash discharge device, the rotating device, the elevating device and the weighing device are all connected with an electric device, and the burning device is connected with a temperature controller; and the measurement unit is connected with the control unit by the electric device. The invention has the advantages of excellent ash collection and discharge effect, high accuracy, no noise and no clamp phenomena.

Description

technical field [0001] The invention relates to a device for measuring residual carbon content of fly ash in ash discharge flue of a thermal power plant boiler based on the weightlessness technology. Background technique [0002] The residual carbon content of fly ash in the boiler flue of a thermal power plant is an important indicator reflecting the combustion efficiency of a coal-fired boiler in a thermal power plant. Real-time detection of the residual carbon content of fly ash will help guide the operation of the boiler, correctly adjust the air-to-coal ratio, and improve the level of combustion control; Reasonable control of the index of residual carbon in fly ash is conducive to reducing the cost of power generation and improving the economy of unit operation. [0003] The boiler flue fly ash carbon residual detection equipment currently in use in domestic power plants basically uses microwave measurement technology to measure the residual carbon content in fly ash, b...
