氢氧化钾在生产的过程中，要进行加热，氢氧化钾生产要先将液碱蒸发，浓缩至一定浓度，然后进行后续加工。
　　In the production process of potassium hydroxide, it is necessary to heat up. In the production of potassium hydroxide, the liquid alkali must be evaporated, concentrated to a certain concentration, and then processed subsequently.
　　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 pot method directly uses fire to heat the alkali pot. The incineration of coal is incomplete. Ash and soot deposit exist in the furnace and the alkali-fixing pot. The heat transfer power is low. In order to save energy, three-pot method is usually used, that is, preheating pot, cooking pot and color matching 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，以满意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-fueled 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 units. The temperature of molten salt fueled with coal entering the furnace is 430 C, which is required for the concentrator. When molten salt is separated from high concentration unit, the temperature is 400 C. It flows into molten salt tank by gravity, and then the molten salt is transported by molten salt pump to circulate the whole molten salt system.
　　氢氧化钾从熔盐炉出来的高温烟道气进入蒸汽发生器，再经过空气预热器降温后进入水膜除尘器，烟气经除尘、脱硫后进入引风机，经引风机引进烟囱排至大气。。
　　Potassium hydroxide enters the steam generator from the high temperature flue gas from the molten salt furnace, and then enters the water film dust collector after cooling by the air preheater. The flue gas enters the induced draft fan after dust removal and desulfurization, and the chimney is introduced by the induced draft fan and discharged to the atmosphere.
