Abstract

The invention belongs to the field of research of reaction dynamics characteristics such as ignition, combustion and gasification of solid fuel particles, and discloses a pressurized plane flame combustion device. A combustor main body of the device is provided with an oxidizing gas cavity and a water cooling cavity; the upper end of the oxidizing gas cavity is opened, and an inner core is arranged in the center of the oxidizing gas cavity; an independent isolated cooling cavity is arranged in the side wall of the oxidizing gas cavity; a base comprises a fuel gas cavity, the fuel gas cavity islocated below the oxidizing gas cavity, and a sealing plate isolates the oxidizing gas cavity form the fuel gas cavity; and a planar flame capillary inner core comprises a honeycomb ceramic block, acapillary array and powder feeding tube. According to the pressurized plane flame combustion device, oxidation gas and fuel gas are transmitted and rectified separately, and finally a stable non-premixed plane flame is formed on the top surface of the honeycomb ceramic block to form a high-temperature and high-heating-rate flue gas environment is formed; and the hot-pressing deformation and heat failure are prevented through water cooling, and the sealing plate is matched with O-shaped rings for sealing, so that the pressurized plane flame combustion device can stably work in a high-temperature and high-pressure environment for a long time.

Description

technical field

[0001] The invention belongs to the research field of reaction kinetic characteristics of discrete solid fuel particles such as ignition, combustion, and gasification, and relates to a pressurized planar flame combustion device, and more specifically, to a tissue controllable high temperature and high pressure device suitable for optical measurement Ambient flat flame combustion device. Background technique

[0002] The reaction kinetic characteristics of micron and nanometer powder fuels such as ignition, combustion and gasification have important reference significance for the design of combustion devices. In practical applications, the powder reaction is often in a relatively extreme high temperature and high pressure environment, and has an extremely high heating rate in the actual combustion environment. Most laboratory equipment is difficult to meet such requirements. Therefore, a combustion system that can provide a high temperature and high pressure ...
