Description
空气热化燃气燃烧器 技术领域 Air heating gas burner
本发明涉及一种燃烧器, 尤其涉及一种普通中式炒炉上用的燃烧器。 背景技术 The present invention relates to a burner, and more particularly to a burner for use in a conventional Chinese type frying furnace. Background technique
目前, 我国国内大、 中、 小饭店使用普通中式炒炉的燃烧器, 存在着以 下不足之处: At present, there are the following shortcomings in the use of burners for ordinary Chinese-style frying stoves in large, medium and small hotels in China:
1.通常用的燃烧器是一边进燃气, 一边用鼓风机强制进空气, 燃烧室 内的燃气燃烧不完全, 雾化不佳, 有部分燃气被高温火焰带走, 污染空气的 同时也带走了大量的热量, 其中被高温火焰带走的热量约占燃气供给总热量 的 20 % - 30 %'左右。 1. The commonly used burner is forced into the air while the gas is being injected into the gas. The combustion of the gas in the combustion chamber is incomplete, the atomization is not good, some of the gas is taken away by the high temperature flame, and the air is also polluted. The heat, which is taken away by the high temperature flame, accounts for about 20% - 30% of the total heat supply of the gas.
2.普通中式炒炉的燃烧器上部的炉圈有开口, 让火焰顺着炒锅流出, 否则会因缺氧而使火焰熄灭, 因此从炉圈开口处高温火焰带走的热量约占燃 气供给总热量的 20 % - 30 %左右。 2. The upper part of the burner of the ordinary Chinese type frying furnace has an opening, letting the flame flow out along the wok, otherwise the flame will be extinguished due to lack of oxygen, so the heat taken away from the high temperature flame at the opening of the furnace ring accounts for the gas supply. 20% - 30% of total calories.
3.普通中式炒炉的燃烧器上部的炉圈没有开口, 必须在炉膛内开口, 让燃烧不完全的部分燃气和剩余的火焰去加热副炉, 同时带走的热量也是约 占燃气供给总热量的 20 % - 30 %左右。 3. The upper part of the burner of the ordinary Chinese type frying furnace has no opening, and must be opened in the furnace to allow some of the incomplete combustion gas and the remaining flame to heat the auxiliary furnace, and the heat taken away also accounts for the total heat of the gas supply. 20% - 30% or so.
从以上三点可以说明, 普通炒炉的燃烧方式, 第一使燃气燃烧不充分 而严重浪费资源, 而燃烧不充的燃气排到空气中也污染了空气, 第二使大量 热能流失, 即加大了对燃气的用量, 又提高了周围环境温度, 第三燃烧的不 充分使一氧化碳和氮气化物严重超标, 恶化了厨房的操作环境, 直接危害了 厨房操作人员的身体健康。 From the above three points, it can be explained that the burning mode of the common frying furnace, the first makes the gas combustion insufficient and seriously wastes resources, while the unburned gas is discharged into the air and pollutes the air, and the second causes a large amount of heat energy to be lost. The use of gas is increased, and the ambient temperature is raised. The insufficient third combustion causes the carbon monoxide and nitrogen compounds to exceed the standard seriously, which deteriorates the operating environment of the kitchen and directly jeopardizes the health of the kitchen operators.
因此人们对普通炒炉的燃烧器进行了改进, 改进的燃烧器大体分为两 类: 一类是改装燃烧器的炉芯, 原中式的炉圈不变, 这类燃烧器改进的结构 不合理, 使其使用的寿命缩短, 而改进后节能的效果也不明显, 另一类是在 原有中式炒炉的基础上改装成一个电子控制的节能器, 叫锅炉启灭装置, 它 的节能在 20 %左右, 因为是电子感应, 用过一段时间之后就失败了。 人们应 用这类改进的燃烧器得不到要得到的经济效益, 而逐步被巿场淘汰。
发明内容 Therefore, people have improved the burners of ordinary fryers. The improved burners are roughly divided into two categories: one is the core of the modified burner, the original Chinese furnace ring is unchanged, and the improved structure of this type of burner is unreasonable. , the life of the use is shortened, and the effect of energy saving after improvement is not obvious. The other type is converted into an electronically controlled energy saver based on the original Chinese type of frying stove, called the boiler start-stop device, and its energy saving is 20 % or so, because it is electronic induction, it has failed after a period of use. The use of such improved burners does not yield the economic benefits to be obtained, and is gradually eliminated by the market. Summary of the invention

This prevents heat loss and also makes the surrounding environment no longer heat up due to heat loss.
本发明的工作原理为: The working principle of the invention is:
鼓风机把空气从进风口、 供风通道、 喷气口鼓吹进入燃烧室, 在燃烧室 内与从供气口经过雾化孔雾化进入燃烧室内的燃气混和并燃烧, 对炒锅进行 加热, 也使燃烧室内气体的温度变高, 大部分燃烧不充分的高温气体(这时 高温气体的温度会达到 800°C以上)会通过回风口, 经过炉圈的内部空腔、 供风通道和喷气口再度回到燃烧室燃烧, 使燃烧不充分的高温气体的热量不 但得到回收利用, 而且能使其充分燃烧, 大大减少了燃气的用量, 并抑制对 人体危害极大的一氧化碳、 氣氢化合物的生成, 同时燃烧室内产生的部分废 气从炒锅和炉圈之间的空隙中排出, 由于炒锅和炉圈之间的空隙很小, 所以 燃烧的火焰不会从缝隙中溢出, 使热量流失较少, 少部分燃烧室内产生的废 气通过废气辅助排气口排出。 The air blower blows air from the air inlet, the air supply passage and the air injection port into the combustion chamber, mixes and burns the gas in the combustion chamber and is atomized into the combustion chamber through the atomization hole, and heats the wok, and also burns The temperature of the indoor gas becomes high, and most of the high-temperature gas that is not fully burned (when the temperature of the high-temperature gas reaches 800 °C or higher) will pass through the return air inlet, and then pass through the internal cavity of the furnace ring, the air supply passage and the air vent. When it is burned in the combustion chamber, the heat of the high-temperature gas that is not burned is not only recycled, but also fully burned, which greatly reduces the amount of gas and suppresses the generation of carbon monoxide and gas-hydrogen compounds that are extremely harmful to the human body. Part of the exhaust gas generated in the combustion chamber is discharged from the gap between the wok and the hob. Since the gap between the wok and the hob is small, the burning flame does not overflow from the gap, so that heat loss is less and less. The exhaust gas generated in part of the combustion chamber is exhausted through the exhaust gas auxiliary exhaust port.
经试验, 本发明节省燃气 65 %左右, 而且循环燃烧使燃烧噪音低, 炉前 温度低, 能抑制对人体危害极大的一氧化碳、 氮氢化合物的生成, 减少了对 环境的污染, 消除对人体健康危害的隐患, 有力的保证了人们的身体健康。 After testing, the invention saves about 65% of gas, and the circulating combustion makes the combustion noise low, the temperature before the furnace is low, the generation of carbon monoxide and nitrogen hydrogen compounds which are extremely harmful to the human body can be suppressed, the pollution to the environment is reduced, and the human body is eliminated. The hidden dangers of health hazards ensure the health of people.
在经济市场竟争中, 各餐饮业都在精打细算核算成本, 以某中型饭店为 例, 现有中式炒炉 50台 (100个燃烧器)全年用气费用 100万元, 如果把 50 台中式炒炉的燃烧器换成本发明, 按最保守的 50 %节气量计算, 每年节约然 气费用 50万元,在能源紧缺的今天,本发明具有积极的经济效益和社会效益。 工业实用性 In the economic market competition, the catering industry is carefully calculating the cost of accounting. Taking a medium-sized restaurant as an example, 50 sets of Chinese-style frying stoves (100 burners) have a gas cost of 1 million yuan per year, if 50 Chinese models are used. The burner of the frying stove is replaced by the invention. According to the most conservative 50% of the solar energy, the annual cost of saving gas is 500,000 yuan. In today's energy shortage, the invention has positive economic and social benefits. Industrial applicability
本发明釆用了上述技术方案, 使鼓风机把空气从进风口、 供风通道、 喷 气口鼓吹进入燃烧室, 在燃烧室内与从供气口进入的燃气混和并燃烧., 对炒 锅进行加热, 同时使燃烧室内气体的温度变高, 大部分燃烧不充分的高温气 体会通过回风口, 经过炉圈的内部空腔、 供风通道和喷气口重新回到燃烧室 助燃和燃烧, 使燃烧不充分的高温气体充分燃烧且热能得到回收利用, 大大 减少了燃气的用量, 节约了能源, 并抑制对人体危害极大的一氧化碳、 氮氢
化合物的生成, 减少了对环境的污染, 消除对危害人体健康的隐患, 同时燃 烧室内产生的部分废气从炒锅和炉圈之间的空隙中排出, 由于炒锅和炉圈之 间的空隙很小, 所以燃烧的火焰不会从缝隙中溢出, 使热量流失较少, 因此 该空气热化燃气燃烧器具有产业上的可利用性。
The invention adopts the above technical solution, so that the air blower blows air from the air inlet, the air supply passage and the air outlet into the combustion chamber, mixes and burns with the gas entering from the air supply port in the combustion chamber, and heats the wok. At the same time, the temperature of the gas in the combustion chamber becomes high, and most of the unburned high-temperature gas passes through the return air outlet, and returns to the combustion chamber to support combustion and combustion through the internal cavity of the furnace ring, the air supply passage and the air outlet, so that the combustion is insufficient. The high-temperature gas is fully burned and the heat energy is recycled, which greatly reduces the amount of gas, saves energy, and suppresses carbon monoxide and nitrogen-hydrogen which are extremely harmful to the human body. The formation of the compound reduces the pollution to the environment and eliminates the hidden dangers to human health. At the same time, part of the exhaust gas generated in the combustion chamber is discharged from the gap between the wok and the hearth, because the gap between the wok and the hearth is very Small, so the burning flame does not overflow from the gap, so that the heat loss is less, so the air heating gas burner has industrial availability.
