Description
技术领域Technical field
本发明涉及一种燃烧器，尤其涉及一种气液两用燃烧器。The invention relates to a burner, in particular to a gas-liquid dual-purpose burner.
背景技术Background technique
火焰是燃烧状态稳定与否最直接的反映，为了探究各种碳氢燃料在不同参数下层流火焰的燃烧机理、各种生成物(碳烟)以及中间产物(PAH)多环芳烃等在燃烧时的组分、燃烧温度和压力之间的关系，出现了各种各样针对层流火焰燃烧的检测方法。近几年非原位检测技术采用激光诱导荧光(LIF)、激光诱导炽光(LII)及消光法(LOSA)等激光检测技术对各种燃烧器、高压燃烧系统中的燃烧层流火焰及碳烟排放特性进行测试研究。Flame is the most direct reflection of whether the combustion state is stable or not. In order to explore the combustion mechanism of laminar flow flames of various hydrocarbon fuels under different parameters, various products (soot) and intermediate products (PAH), polycyclic aromatic hydrocarbons, etc. Based on the relationship between the components, combustion temperature and pressure, various detection methods for laminar flame combustion have emerged. In recent years, ex-situ detection technology has used laser detection technologies such as laser-induced fluorescence (LIF), laser-induced incandescence (LII) and extinction method (LOSA) to detect laminar combustion flames and carbon in various burners and high-pressure combustion systems. Smoke emission characteristics were tested and studied.
层流火焰就是管内静止气体或作层流流动气体点燃时形成的火焰，层流火焰比较稳定，测量时波动小，适用于原子吸收定量分析。预混合型燃烧器产生层流火焰，所以也称层流燃烧器，燃气和助燃气在雾室中混匀，然后以层流状态从燃烧器头喷出，其特点是能产生稳定的层流扩散火焰，边界条件简单，燃烧可重复性好。Laminar flame is a flame formed when stationary gas or laminar flowing gas in a tube is ignited. Laminar flame is relatively stable and has small fluctuations during measurement, and is suitable for quantitative atomic absorption analysis. The premixed burner produces a laminar flow flame, so it is also called a laminar flow burner. The gas and supporting gas are mixed evenly in the mist chamber, and then ejected from the burner head in a laminar flow state. It is characterized by the ability to produce a stable laminar flow. Diffusion flame has simple boundary conditions and good combustion repeatability.
目前的层流燃烧器主要是燃烧气体燃料，不适用液体燃料。由于液体燃料无法控制燃料消耗量、火焰很难稳定在同一条件下并且重复性差等原因限制了液体燃料的燃烧过程研究。因此，有必要提供一种能够产生稳定、压力可以调节、相对于定光源位置可以调节的层流火焰并且适用气体燃料和液体燃料燃烧的气液两用燃烧器。Current laminar flow burners mainly burn gaseous fuels and are not suitable for liquid fuels. Research on the combustion process of liquid fuels is limited by the fact that liquid fuels cannot control fuel consumption, the flame is difficult to stabilize under the same conditions, and the repeatability is poor. Therefore, it is necessary to provide a gas-liquid dual-purpose burner that can produce stable laminar flow flames with adjustable pressure and adjustable position relative to a fixed light source and is suitable for burning gaseous fuels and liquid fuels.
