Abstract

The present invention relates to an inclined internal heat type liquid vapor combustion performance testing device, the inclined internal heat type liquid vapor combustion performance testing device comprises a support arranged on a horizontal plane, an inclined internal heat unit which is arranged obliquely in relative to the horizontal plane and fixed on the support, a vapor ignition nozzle tube which is vertically arranged and connected with the internal heat unit, and a combustion test unit which is matched with the inclined internal heat unit and the vapor ignition nozzle tube. Compared with the prior art, the inclined internal heat type liquid vapor combustion performance testing device has the advantages of simple and compact overall structure, wide application range, small amount of a test sample, fast and flexible operation, high testing precision, reduction of the amount of the test sample, quick adjustment of temperature by use of an internal heating element, energy saving, increase of safety, and very good application prospects.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to a combustion performance testing device of an inclined internal heating type liquid vapor. Background technique [0002] With the improvement of management requirements and levels of production, storage and transportation, the demand for chemical risk assessment is also increasing. Especially in the construction of "green ports" advocated in recent years, the identification and identification of hazardous chemicals In the most important position. For liquid chemicals, combustion performance testing is an essential part of risk assessment. At present, the flash point is usually used as an indicator to indicate the explosion hazard of flammable liquids, that is, the lowest temperature at which a flammable liquid can emit a sufficient amount of vapor and form a flammable mixture with air at the surface of the liquid in the container used. The flash point test can be divided into clo...
