Embodiment Construction

[0021] In order to better understand the technical content of the present invention, specific embodiments are given together with the attached drawings for description as follows.

[0022] The invention proposes a method for measuring the deposits of steam turbine blades. The blade deposits are processed into a solution at one time, and the main components of the deposits mainly covered at present can be measured at one time on related instruments.

[0023] Please refer to figure 1 , figure 1 Shown is a flow chart of a method for measuring deposits on a steam turbine blade according to a preferred embodiment of the present invention. The steam turbine blade deposit determination method that the present invention proposes comprises the following steps:

[0024] Step S100: collecting sediment samples;

[0025] Step S200: mixing the sediment sample, lithium borate and lithium metaborate mixture and heating to melt;

[0026] Step S300: taking out the melted mixture and cooling...

Abstract

The invention provides a blade deposit sediment measuring method for a turbine, which comprises the following steps: collecting a deposit sediment sample; heating and fusing the mixture of the deposit sediment sample, lithium tetra borate and lithium metaborate; taking out the mixture obtained by fusing and cooling to room temperature; socking the mixture into a hydrochloric acid or salpeter solution; heating the solution and stirring; carrying out constant volume on the solution; and measuring the solution to obtain the components in the deposit sediment sample. The blade deposit sediment measuring method for the turbine provided by the invention processes the blade deposit sediment into the solution at a time, so that the method can measure the main body component of the mainly contained deposit sediment on the related instrument at a time.

Description

technical field [0001] The invention relates to the field of determination of steam turbine deposits, and in particular relates to a determination method of steam turbine blade deposits. Background technique [0002] The steam turbine blades used in power stations often deposit certain substances. Determining the composition of the sediments helps to understand the operation mode and adjust the operation mode in a targeted manner. At present, the determination of chemical elements in leaf sediments is performed after pretreatment, making them into solutions, and then measuring with related instruments. It is an inevitable process to process solid sediments into solutions. The general method requires several times of pretreatment before measuring separately. . At present, the main determination of sediment components includes K, Na, Ca, Mg, Fe, Si, Al, Ti, Mn, S, P, Ni, Cu, etc. The main problem of conventional testing methods is that they cannot be pretreated at one time. ...
