A temperature self-regulating flameless combustion device

Abstract

The invention discloses a flameless combustion device with a temperature self-adjusting function. The flameless combustion device comprises a shell, a heat preservation layer and a furnace pipe; the furnace pipe is sequentially divided into a first reaction area and a second reaction area from outside to inside, a plurality of flameless combustion pipes are evenly arrayed at the edge of the firstreaction area at intervals, the first reaction area is filled with a first medium, the second reaction area is arranged at the center of the first reaction area and comprises a heat conducting pipe, the heat conducting pipe is filled with a second medium, and a natural gas pipeline is further arranged at the center of the heat conducting pipe; and the first reaction area and the second reaction area are internally provided with a first temperature collecting unit and a second temperature collecting unit correspondingly. According to the flameless combustion device, by controlling a flow control valve in a fuel mixing area, controlling the amount of flameless combustion and conducting heat through heat radiation of the double media, the influence of the instantaneous high temperature on a reactant is avoided, and meanwhile, the temperature can further be adjusted finely.

Description

technical field [0001] The invention relates to the field of flameless combustion devices, in particular to a flameless combustion device with self-regulating temperature. Background technique [0002] Flameless combustion technology is a new type of low-pollution combustion technology. There will be no obvious flame surface during combustion, a large amount of heat will be generated during combustion, and no polluting gas will be produced and released after combustion. Especially in the existing flameless combustion of methanol, a large amount of heat should be generated when methanol is contacted with a catalyst. The whole process is simple and fast, which provides a new direction for industrialization development. [0003] Due to the rapid reaction and rapid release of heat, the existing flameless combustion cannot control the temperature of flameless combustion, especially when heating natural gas or petroleum compounds. The flameless combustion of flameless combustion u...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a flameless combustion device with self-adjusting temperature, which solves the problem that traditional flameless combustion produces a large amount of heat and cannot control the temperature in the reaction process. This application can control the fuel mixing The flow control valve in the zone and the amount of controlled flameless combustion, as well as the heat conduction heat of the dual medium heat radiation, avoid the impact of instantaneous high temperature on the reactants, and at the same time finely adjust the temperature
