氫氧化鉀在生產的過程中，要進行加熱，氫氧化鉀生產要先將液堿蒸發，濃縮一定濃度，然后進行后續加工。

　　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.

　　傳統的鍋式法直接用火加熱堿鍋，煤焚燒不完全，灰分及煤煙垢積存在爐膛及固堿鍋上，傳熱功率低。為了節約能源，通常選用三連鍋法；即預熱鍋、蒸煮鍋和調色鍋。

　　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.

　　氫氧化鉀熔鹽加熱單元是以煤為燃料的熔鹽加熱體系，該體系用來操控抵達濃縮器的熔鹽的溫度，以滿意高濃度單元的工藝需求。以煤為燃料的熔鹽進入爐子溫度為濃縮器所需的溫度430℃。熔鹽脫離高濃度單元時的溫度為400℃，經過重力流入熔鹽罐，然后用熔鹽泵運送熔鹽來循環整個熔鹽體系。

　　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.

　　氫氧化鉀從熔鹽爐出來的高溫煙道氣進入蒸汽發生器，再經過空氣預熱器降溫后進入水膜除塵器，煙氣經除塵、脫硫后進入引風機，經引風機引進煙囪排大氣。。

　　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.
