Quick heating and gasifying test device and application thereof

Abstract

The invention relates to a quick heating and gasifying test device; the middle part of a reaction tube (3) is positioned in a tubular electric heating furnace (4); an air inlet hole (6) is formed in the bottom end of the reaction tube (3); a filler layer (7) is arranged in the lower part of the reaction tube (3); a cooling water device (10) is arranged outside the reaction tube (3) on the tubular electric heating furnace (4); a charging valve (2) is arranged on the reaction tube (3) on the cooling water device (10); an air outlet hole (1) is formed in the charging valve (2); a side air outlet hole (9) is formed in the reaction tube (3) between the cooling water device (10) and the charging valve (2); a thermocouple (8) is arranged in the middle of the reaction tube (3) on the filler layer (7). The quick heating and gasifying test device is simple in structure, convenient to operate, and suitable for quickly heating and gasifying various solid carbon-containing matters such as coal and petroleum coke in various atmospheres at a certain temperature; the device also has the advantages of continuously measuring a gasified product and automatically recording the gasification reactivity.

Description

technical field [0001] The invention belongs to a test device and application, in particular to a test device and application for gasification characteristics of coal, petroleum coke and other solid carbonaceous substances under rapid temperature rise conditions. Background technique [0002] Solid carbonaceous substances such as coal and petroleum coke are used as raw materials for gasification, and it is necessary to master their gasification reactivity at different temperatures and atmospheres. Thermogravimetric analyzers have been widely used in the study of gasification reactivity. This instrument can directly measure the change of the mass of solid carbonaceous substances with time. However, the heating rate of ordinary thermogravimetric is slow, and the operating temperature is low, so it can only conduct thermogravimetric test on trace samples, and cannot obtain data under the condition of rapid heating. Foreign high-temperature thermogravimetry is relatively expens...

AI Technical Summary

Problems solved by technology

However, the heating rate of ordinary thermogravimetric is slow, and the operating temperature is low, so it can only conduct thermogravimetric test on trace samples, and it is impossible to obtain data under the condition of rapid heating

Foreign high-temperature thermogravimetry is relatively expensive, the gasification atmosphere is relatively simple, and the operation is cumbersome, the test time is long, and the gasification characteristics of samples under different conditions cannot be obtained.
