       随着人类科技的高速发展，对地球能源的需求和消耗也越来越高。但是地球的资源是有限的，毫无节制的滥用能源，最后的结果只能是招来大自然的报复。而煤炭资源更是现代工业的主要能源之一。锅炉则又是煤炭资源的消耗大口。所以为了相应进入“十二五”规划以来，建设资源节约型、环境友好型的和谐社会的目标。
    工业锅炉的主要燃料是煤炭，其次是重油。燃煤锅炉产生的烟尘由两部分组成：一部分是煤炭受热分解，在高温缺氧情况下析出的微小炭黑，粒径一般小于1μm，称为黑烟；另一部分是随烟气带走的飞灰。燃煤锅炉产生的烟尘量与煤的成分、锅炉炉型、燃烧方式和操作制度等有关。燃油锅炉产生的烟尘性质随重油成分、炉型、燃烧器结构和燃烧条件而异，烟尘中主要是未燃烬的炭黑，由20μm左右和0.02μm的微粒组成。工业锅炉产生的黑烟主要靠改进燃烧解决，飞灰等主要靠烟气除尘来解决。
改进燃烧在锅炉中使燃料完全燃烧，可以有效地减少黑烟产生。在燃料燃烧过程中，保证燃料燃烧所需空气量、燃烧温度和燃料与空气的充分混合，是实现燃料完全燃烧的条件。一般工业锅炉的空气过剩系数取10％～40％，对于机械燃煤炉和燃油炉取小些，对于手工烧炉则取大些。为保证炉膛热强度和燃料与空气的充分混合，往往采取机械化操作、控制燃料投量和附加二次风等措施，皆可改进燃烧，减少黑烟污染。
    烟气除尘消除飞灰污染的主要措施。工业蒸汽锅炉烟气除尘常用的除尘装置有：(1)旋风除尘器。特点是结构简单，投资较少，除尘效率一般为90％左右，运行阻力为0.8～1.6kPa。多用于中小型锅炉。(2)湿式除尘器。锅炉烟气除尘中常用的有旋风水膜除尘器，麻石水膜除尘器、斜棒栅除尘器和文丘里除尘器等，特点是投资较少，除尘效率较高，一般为85％～95％，有的可达99％，且兼有除尘和脱硫等功能，但洗涤水需经处理后才能排放或循环使用。多用于中型锅炉。

   With the rapid development of human science and technology, for the earth is becoming more and more high energy demand and consumption. But the earth's resources are limited, unrestrained abuse of power, the end result is only recruit to the revenge of nature. The coal resource is one of the main energy of modern industry. The boiler and coal resource consumption swig. Corresponding entering the "twelfth five-year" plan, so in order to build an energy-efficient and environment-friendly harmonious society goal.
Industrial boiler's main fuel is coal, followed by heavy fuel oil. Coal-fired boiler soot produced consists of two parts: part of coal thermal decomposition, and under the condition of high temperature oxygen precipitation of tiny carbon black, the average particle size less than 1 mu m, known as black smoke; The other part is the fly ash with the smoke away. The smoke from coal-fired boiler and coal composition, boiler furnace type, burning mode and operating system and so on. Nature of the fuel oil boiler soot produced along with the crude oil composition, furnace type, the structure of the burner and combustion condition varies, smoke is not combustion of carbon black state, by about 20 microns and of particles of 0.02 microns. Industrial boiler to produce black smoke depend mainly on the improvement of combustion, mainly by flue gas dust removal such as fly ash to solve.
Improved combustion make the fuel combustion in the boiler, can effectively reduce the black smoke is generated. In the process of fuel burning, required air quantity guarantee fuel combustion, combustion temperature and fuel and air mixing, is to realize the fuel combustion conditions. General industrial boiler air excess coefficient of 10% ~ 40%, the mechanical coal furnace and oil furnace, furnace was larger for manual. In order to ensure the furnace heat intensity and the fuel and air mixing, often take mechanization operation and control fuel dosage and additional secondary measures such as wind, all can improve combustion, reduce black smoke pollution.
The flue gas dust removal measures to eliminate the pollution of fly ash. Industrial steam boiler flue gas dust removal has: (1) the cyclone dust removal device. Is characterized by simple structure, less investment, the dust removal efficiency is generally around 90%, running resistance from 0.8 to 0.8 kPa. Used for middle and small boiler. (2) the wet type dust collector. That is commonly used in boiler flue gas dust removal has a cyclone water film precipitator, the granite water film dust collector, oblique rods and venturi grid filter dust collector, etc., is characterized by less investment, higher dust removal efficiency, is commonly 85% ~ 95%, and some can be up to 99%, and both dust removal and desulfurization, and other functions, but the washing water should be treated before discharge or recycled. More for medium boiler.
