A detachable solid fuel suspension combustion experimental test device and test method

Abstract

The invention discloses a detachable solid fuel suspension combustion experiment testing device and a detachable solid fuel suspension combustion experiment testing method, belonging to the technical field of a solid fuel combustion experiment. The testing device comprises a suspension combustion mechanism, a combustion data acquisition mechanism, a gas supply mechanism and an ignition mechanism; a base is arranged on a base bracket; the lower end hole of a primary combustion pipe is communicated and in detachable connection with the upper end hole of an inner pipe of the base; the lower end hole of a secondary combustion pipe is communicated and in detachable connection with the upper end hole of the primary combustion pipe; two porous metal plates are respectively arranged at the upper end hole of the inner pipe of the base and the upper end hole of the primary combustion pipe. The testing method comprises the steps of placing fuel; enabling the fuel to suspend; burning; acquiring combustion data; finishing the experiment. The device and the method mainly have the functions of realizing visualization of a combustion state, realizing uniform combustion at a suspended state, carrying out a combustion test on multiple samples for once and enabling the large-particle samples to be easily ignited.

Description

technical field [0001] The invention belongs to the technical field of solid fuel combustion experiments, and more specifically relates to a detachable solid fuel suspension combustion experimental testing device and testing method. Background technique [0002] At present, there are many combustion experiment test devices on the market, such as thermal analyzers, tube furnaces, etc. But most of these combustion experiment test devices have the following disadvantages: (1) visual sealing. Because the sample tanks of these combustion devices are placed inside the instrument, the combustion characteristics of the sample can only be analyzed through some specific numerical parameters during the experiment, but the combustion state of the sample cannot be observed intuitively; (2) non-uniform combustion . In these instruments and devices, the samples are mostly placed in the sample tank in the form of piles and burned in a static state. Although the ignition and combustion of ...
