Embodiment 1

[0066] as attached figure 1 As shown, the movable impact fly ash sampler of the present invention mainly includes a fly ash sampling pipe 2, a plug 1, and a hanging hole 3, and the material is stainless steel. A hanging rod is installed in the flue through the hanging hole for fly ash sampling. When placing the fly ash sampler, the oblique opening faces the flue gas flow direction. The fly ash sampler itself is a fly ash storage device.

[0067] Sampling is performed on representative points of the equal-area surface by the grid method. The division principle of the equal-area surface of the grid method and the determination of representative points: the section is divided into several equal-area rectangles close to the square by the longitude and latitude lines, and the intersection points of the diagonals of each small rectangle are the measuring points.

[0068] The determination of the side length L of the rectangular section and the number of rows of measuring points ...

Abstract

The invention discloses a movable impact type fly ash sampler. The sampler comprises a pipe body (2) and a pipe orifice (2-1) positioned at the front end of the pipe body (2), wherein the pipe orifice(2-1) is in the shape of an arc or a V-shaped inclined plane. According to the fly ash sampler disclosed by the invention, the problems that the quantity of conventional fixed fly ash sampling pointsis small and the representativeness is poor can be effectively solved. The movable impact type fly ash sampler is developed first, and fly ash sampling can be representatively performed. The fly ashsampling device is simple and practical. The fly ash sampling operation is simple, the sampling is convenient, the sampling operation can be completed by a single person, and the sampling representativeness is high.

Description

technical field [0001] The invention relates to a coal-fired boiler movable impact type fly ash sampler, in particular to a coal-fired boiler daily fly ash sampling device that does not need power and has a representative boiler sampling position, belonging to a coal-fired power generation boiler system. technical background [0002] The representativeness of boiler fly ash sampling affects whether the carbon content of boiler fly ash is correct or not. The carbon content of boiler fly ash directly affects the boiler efficiency. The carbon content of fly ash is an important indicator to measure the combustion status of boilers. [0003] Boiler fly ash sampling is divided into two categories. One is the fly ash sampling required for boiler performance assessment test or regular boiler thermal efficiency test. Second, for the daily fly ash sampling and analysis of coal-fired boilers in power generation enterprises, it is necessary to install 1 One or several sets of special f...
