In the process of production, potassium hydroxide needs to be heated. In the process of production, the liquid alkali should be evaporated and concentrated to a certain concentration before subsequent processing. But do you know how it is heated? Let's talk about it in detail.

　　传统的锅式法直接用火加热碱锅，煤焚烧不完全，灰分及煤烟垢积存在炉膛及固碱锅上，传热功率低。为了节约能源，通常选用三连锅法；即预热锅、蒸煮锅和调色锅。

　　The traditional boiler method uses fire to heat the alkali boiler directly. The coal combustion is incomplete. The ash and soot deposit in the furnace and the alkali fixing boiler, so the heat transfer power is low. In order to save energy, the three connected pot method is usually used, that is, preheating pot, cooking pot and color mixing pot.

　　氢氧化钾熔盐加热单元是以煤为燃料的熔盐加热体系，该体系用来操控抵达浓缩器的熔盐的温度，以满足高浓度单元的工艺需求。以煤为燃料的熔盐进入炉子，温度为浓缩器所需的温度430℃。熔盐脱离高浓度单元时的温度为400℃，经过重力流入熔盐罐，然后用熔盐泵运送熔盐来循环整个熔盐体系。

　　Potassium hydroxide molten salt heating unit is a coal-fired molten salt heating system, which is used to control the temperature of molten salt reaching the concentrator to meet the process requirements of high concentration unit. The molten salt with coal as fuel enters the furnace, and the temperature is 430 ℃ required by the concentrator. When the molten salt is separated from the high concentration unit, the temperature is 400 ℃, which flows into the molten salt tank through gravity, and then the molten salt is transported by the molten salt pump to circulate the whole molten salt system.

　　上述的内容就是氢氧化钾的加热方式的内容，大家都已经有更进一步的学习了，另外，它从熔盐炉出来的高温气进入蒸汽发生器，再经过空气预热器降温后进入水膜除尘器，脱硫后进入引风机，经引风机引进烟囱排大气。

　　The above content is the content of the heating method of potassium hydroxide, which has been further studied. In addition, the high-temperature gas from the molten salt furnace enters the steam generator, then enters the water film dust collector after cooling through the air preheater, enters the induced draft fan after desulfurization, and then enters the chimney through the induced draft fan to exhaust to the atmosphere.
