Description
Technical field
The present invention relates to waste heat boiler technical field, particularly a kind of residual heat boiler of steel ball dedusting type ore heat furnace.
Background technology
At present, a large amount of energy resource consumptions is needed in various field of industrial production, by various thermal power transfer equipment in production process, answer in equipment with energy equipment and chemistry side and produce and unemployed heat energy, and a large amount of various forms of waste heats can be produced in process of production, the source of waste heat mainly contains industrial exhaust gas waste heat, the waste heat of high-temperature product and slag, the waste heat of cooling medium, chemistry side answer generate in process abandon heat, combustible exhaust gas, waste material, the heat energy of waste liquid and waste vapour, the waste heat of waste water, and the evenly heat efficiency of Industrial Boiler only has 67 ﹪, remaining energy passes through the useless fume emission of high temperature in the middle of air, cause great waste.
The UTILIZATION OF VESIDUAL HEAT IN of Boiler Manufacturing Industry be energy-conservation at present in an important topic, it has very high economic benefit and social benefit.Such as, the smelting furnace UTILIZATION OF VESIDUAL HEAT IN in Boiler Manufacturing Industry, is converted to other energy by the used heat of being discharged by smelting furnace, as electric energy, steam-energy or directly go to drive other plant equipment and heat supply as power.
Mineral hot furnace generally divides 3 kinds of type of furnaces, and the first is Totally-enclosed-type, and the second is that low hood is type semienclosed, and the third is high petticoat pipe open type.The fuel gas that semi-hermetic stove contains due to it is very little, temperatures as high more than 400 DEG C, and the air be mixed into from fire door is more, and exhaust gas volumn is larger.Be applicable to adopting residual heat boiler for exchanging heat generating, the thermal efficiency can reach about 26% ~ 28%, but difficult point is that the diameter of most of dust in flue gas is 0.1 ~ 0.5um, and is made up of the pelletizing of spherical particle and these particulates, containing SiO in dust
