Description

燃烧器的火排Burner fire row 技术领域Technical field
本实用新型属于机械技术领域,涉及一种火排,特别是一种燃烧器的火排。The utility model belongs to the technical field of machinery, and relates to a fire radiator, particularly a fire radiator of a burner.
背景技术Background technique
燃气热水设备,如燃气热水器或燃气锅炉中通常设置有的燃烧器、热交换器、以及容纳燃烧器和热交换器的燃烧室。燃烧器往往包括有并排设置的若干火排片,每一个火排片具有燃气-空气的混合通道,可在其内将燃气和空气混合并传递给位于火排片顶部的火孔以在燃烧室内燃烧并生成热量,生成后的热量可加热热交换器内的水,从而被加热的水可用于饮用、洗浴、或供暖等。Gas hot water equipment, such as gas water heaters or gas boilers, are usually equipped with burners, heat exchangers, and combustion chambers containing the burners and heat exchangers. Burners often include several fire platoons arranged side by side, and each fire platoon has a gas-air mixing channel, which can mix gas and air in it and pass it to the fire hole on the top of the fire plat to burn and generate in the combustion chamber. Heat, the generated heat can heat the water in the heat exchanger, so that the heated water can be used for drinking, bathing, or heating.
目前,燃烧器已广泛应用于各个家庭中,例如燃气灶、壁挂炉等家庭用品,现有的壁挂炉是一种以天然气为能源的热水器,具有防冻保护、防干烧保护、意外熄火保护、温度过高保护、水泵防卡死保护等多种安全保护措施。壁挂炉具有强大的家庭中央供暖功能,所以被广泛应用,而众所周知,壁挂炉中的燃烧器是壁挂炉性能和效率的关键部件,所以火排组件作为燃烧器的主要组成部件,其性能就显得尤为重要。在实际的工作中,由于火排组件设计的缺陷,存在着燃烧器燃烧不充分的问题,导致燃烧器排放的烟气含有的氮氧化物的含量比较高。At present, burners have been widely used in various households, such as gas stoves, wall-hung boilers and other household appliances. The existing wall-hung boiler is a water heater that uses natural gas as energy. It has anti-freeze protection, dry-burn protection, accidental flameout protection, Various safety protection measures such as over-temperature protection and water pump anti-jamming protection. Wall-hung boilers have powerful household central heating functions, so they are widely used. As we all know, the burner in wall-hung boilers is a key component of the performance and efficiency of wall-hung boilers. Therefore, the fire grate assembly is the main component of the burner, and its performance appears Particularly important. In actual work, due to the design defects of the fire exhaust assembly, there is a problem of insufficient combustion of the burner, resulting in a relatively high content of nitrogen oxides in the flue gas emitted by the burner.
如中国专利文献公开的一种低氮燃烧器火排组件(申请号:201721560894.5),包括火排及设置在火排上端的火孔片,火排内部的两端设置有两个相连通的文丘里管,文丘里管为下端窄并逐渐向上扩大的进气管道,两个文丘里管的上端均设置有导流压槽, 两个文丘里管之间设置有若干个冷却管孔,火孔片上端均匀开设有若干个火孔,文丘里管与若干个所述火孔相连通。但该低氮燃烧器火排组件的进气管道呈垂直设置,应该容易产生回火,降低了燃烧效率。For example, a low-nitrogen burner fire row assembly (application number: 201721560894.5) disclosed in the Chinese Patent Literature includes a fire row and a fire hole piece arranged at the upper end of the fire row. Two connected venturis are provided at both ends of the fire row. The inner tube, the venturi tube is an air inlet pipe with a narrow lower end and gradually expanding upward. The upper ends of the two venturi tubes are equipped with diversion pressure grooves, and a number of cooling pipe holes and fire holes are arranged between the two venturi tubes. A number of fire holes are uniformly opened on the upper end of the film, and the venturi tube is connected with the plurality of fire holes. However, the intake duct of the fire exhaust assembly of the low-nitrogen burner is vertically arranged, which should be prone to backfire, which reduces the combustion efficiency.
