·燃气锅炉的优越性

时间:2017-02-22   作者:
下面锅炉网的小编跟大家介绍燃气锅炉的优越性。 近几年由于雾霾越来月严重,燃煤锅炉逐渐在拆除中,能够降低空气污染,逐渐替换燃煤锅炉。 小编为你介绍燃气锅炉的优越性分析:   (一)、由于燃气中的灰分、含硫量和含氮量均比煤中的含量低,燃烧后产生的烟气中粉尘量极少,排放出的烟气比较容易达到国家对燃烧设备所求的标准。使用燃气锅炉可以大大减轻对环境的污染。   (二)、燃气的炉膛容积热强度较高,由于烟气污染小,对流管束不受腐蚀和结渣,传热效果好,燃气燃烧产生大量三原子气体(二氧化碳、水蒸气等)的辐射能力较强,而且排烟温度低,使其热效率明显提高。   (三)、在节约锅炉设备投资方面;   1、燃气锅炉可选用较高的炉膛热负荷,从而缩小炉膛体积。因不存在受热面污染、结渣、磨损等问题,可选用较高的烟速,减小对流受热面的尺寸。通过合理布置对流管束,使燃气锅炉较同容量燃煤锅炉结构紧凑、尺寸小、重量轻,设备投资明显减少;   2、燃气锅炉不需要配置吹灰器、除尘器、出渣设备和燃料烘干器等附属设备;   3、使用管道输送的燃气为燃料,无需燃料储存设备。在供给燃烧前也无需燃料加工制备设备,使系统大为简化;   4、由于无需燃料储存,节省运输费用、场地及劳动力。   (四)、在运行、调节及降低供热成本方面;   1、燃气锅炉的供热负荷适应性强,在系统内调节灵活。   2、系统启动快,减少预备工作带来的各种消耗。   3、由于附属设备少,又无燃料制备系统,因而用电量较燃煤锅炉要低。   4、不需要加热燃料及燃料烘干所用的蒸汽,蒸汽消耗较少。   5、燃气内杂质较少,不会发生高、低温受热面的腐蚀,也不存在结渣的问题,锅炉的连续运行周期长。   6、燃气计量简单准确,便于燃气供应量的调节。

英文:Below the small series of boiler net to introduce the advantages of gas boiler. In recent years, due to the haze is more serious, coal-fired boilers are gradually removed, gas boiler can reduce air pollution, and gradually replace coal boiler. Small series for you to introduce the advantages of gas boiler: (a), due to the gas in the ash, sulfur content and nitrogen content are lower than the content of coal, combustion flue gas produced in very little dust, exhaust gas is easier to reach the national standard for combustion equipment. The use of gas boiler can greatly reduce the pollution of the environment. (two), gas boiler furnace volume heat intensity is higher, because the gas pollution is small, the convection tube bundle is not corroded and the slag, the heat transfer effect is good, gas combustion produces a large number of three atomic gas (carbon dioxide, water vapor, etc.) the radiation ability is strong, and the exhaust gas temperature is low, so that the thermal efficiency is significantly improved. (three), in terms of saving the investment of boiler equipment; 1, gas boiler can choose a higher furnace heat load, so as to reduce the furnace volume. Because there is no such problems as heating surface fouling, fouling, wear and so on, the high smoke velocity can be used to reduce the size of the convection heating surface. Through reasonable arrangement of convection tube bundle, the gas boiler is more compact, small size, light weight and less equipment investment; 2, gas boiler does not need to be configured to blow dust collector, dust remover, slag equipment and fuel drying equipment and other ancillary equipment; 3, gas boiler uses the gas as fuel, no fuel storage equipment. The system is simplified by the use of the equipment without the need of fuel before combustion; 4, due to the lack of fuel storage, transportation costs, space and labor. (four), in the operation, adjustment and reduce heating costs; 1, gas boiler heating load adaptability, in the system to adjust the flexibility. 2, the system starts quickly, reduce the consumption of preparatory work. 3, due to the subsidiary equipment less, and no fuel preparation system, and so the power consumption is lower than the coal-fired boiler. 4, do not need to heat the fuel and fuel drying used by steam, steam consumption less. 5, less gas, the boiler will not occur high, low temperature heating surface corrosion, there is no problem of the existence of the problem, the boiler's continuous operation cycle is long. 6, gas measurement is simple and accurate, easy to adjust the gas supply. Below the boiler network dedicated to the boiler, steam boiler, gas boiler manufacturing, product quality is good, the price is reasonable, by the majority of customers in the industry, if you have any need to consult us! 文章来源:
