Ash fusion tester

Abstract

The invention discloses an ash fusion tester comprising a high-temperature furnace, an ash cone supporting plate, a graphite cup, an image taking mechanism and a control mechanism, wherein the high-temperature furnace is internally provided with an alundum tube; the ash cone supporting plate and the graphite cup are both arranged in the alundum tube; the ash cone supporting plate comprises more than two supporting plate bodies which are sequentially arranged form top to bottom; and the supporting plate bodies are provided with more than one ash cone hole for holding an ash cone. The invention provides the ash fusion tester with simple and compact structure, low cost, high degree of automation and high overall efficiency.

Description

Technical field [0001] The invention mainly relates to the field of coal sample measurement equipment, and particularly refers to a measurement equipment for coal ash. Background technique [0002] The melting characteristics of coal ash are directly related to whether the boiler of a power plant is slagging (commonly known as coking) and its severity, so it has a great bearing on the safe and economic operation of the boiler. In the prior art, an ash fusibility tester is generally used to determine the ash fusibility of coal samples. At present, the existing ash fusibility tester includes a high temperature furnace, a ash cone support plate, a graphite cup, an imaging mechanism and a control mechanism. The ash cone of the coal sample to be tested is placed on the ash cone support plate and completed in the high temperature furnace. When heating, the image signal of the ash cone at each temperature is collected by the imaging mechanism, thereby automatically or manually judging ...

AI Technical Summary

Problems solved by technology

The deficiencies of the existing structure are: 1. The ash cone supporting plates all adopt a single-layer structure. Due to structural limitations, only four or five ash cones can be measured at a time, and it often takes 3.5 hours to carry out an ash melting test. It takes a long time, so the efficiency is relatively low; 2. When the ash cone is in a molten state at high temperature, it will flow down the side of the ash cone support plate, so that the ash cone support plate is bonded to other connected parts, which is not easy to handle ; 3. Sampling is done manually, and the efficiency is very low; 4. Sampling is done in the high-temperature furnace or near the furnace mouth, which is easy to cause personal injury
