              熱風爐主要是為糧食烘干塔提供熱源,利用熱風來對物料進行烘干處理成都收賬,如果熱風溫度過低成都找人公司話,會影響到烘干效率,熱風溫度過高成都收賬話又會造成糊料,如果想保證糧食烘干塔收賬烘干效率和效果,就得控制好熱風成都找人公司溫度。糧食烘干塔烘干物料所用的熱風是由熱風爐提供的,操作好熱風爐的話,就可以有效地控制熱風的溫度,為了幫助糧食烘干塔用戶提高設備的效率,如果正確地操作糧食烘干塔熱風爐,不僅能夠增加提供熱量的利用率,而且還能節約能源,減少成本。那么如何來利用熱風爐來提高糧食的烘干效率?

              Hot air stove mainly provides heat source for grain drying tower. Hot air is used to dry materials. If the temperature of hot air is too low, it will affect the drying efficiency. If the temperature of hot air is too high, it will cause paste. If we want to ensure the drying efficiency and effect of grain drying tower, we must control the temperature of hot air. The hot air used for drying materials in grain drying tower is provided by the hot air stove. If the hot air stove is well operated, the temperature of the hot air can be effectively controlled. In order to help the users of grain drying tower to improve the efficiency of equipment, if the hot air stove of grain drying tower is properly operated, not only the utilization rate of heat but also the utilization rate of heat can be increased. It can save energy and reduce costs. So how can we use hot blast stove to improve the drying efficiency of grain? 1、在進行裝料的同時供熱熱風爐應點火預熱:首先調節引風機點燃引燃物,填入木材,人工加煤使煤層逐步燃燒旺盛;再根據燃燒情況將煤火逐步撥到熱風爐前拱,使前拱加熱直至從煤閘進入爐膛的燃煤能自動燃燒。此過程一般要在兩小時左右,要隨時觀察煙氣溫度,保證成都找人公司、換熱器不急劇升溫,換熱器內不產生大量積溫。在供熱主風機沒開動,沒有強制空氣流過換熱器的情況下,成都收賬公司煙氣溫度不許超過攝氏300℃;

              1. While charging, the hot blast stove should be ignited and preheated. Firstly, the induced draft fan should be adjusted to ignite the igniter, and the wood should be filled. Then, the coal seam will be gradually burned vigorously by adding coal manually. Then, according to the combustion situation, the coal fire will be gradually shifted to the front arch of the hot blast stove, so that the front arch can be heated until the coal fired from the coal gate into the furnace can be automatically burned. This process usually takes about two hours. The flue gas temperature should be observed at any time to ensure that the hot stove and heat exchanger do not rise sharply and that a large amount of accumulated temperature does not occur in the heat exchanger. The flue gas temperature of hot blast stove should not exceed 300 degrees Celsius when the main fan of heating is not started and no forced air is flowing through the heat exchanger.

              2、如成都收賬公司屬新建或大修,必須事先完成烘爐作業后方可進行烘干作業;

              2. If the hot stove is newly built or overhauled, the oven must be completed before it can be dried.

              3、熱風爐完成供熱準備后可向糧食烘干塔供熱,按操作規程依次開啟冷風機、熱風機。使用PLC自控系統控制時要注意掌握糧食烘干塔的啟動順序和間隔,使用手動控制時要注意各風機、設備之間的啟動間隔;啟動風機前必須關閉風機入口風門,正常運轉后方可打開;要根據不同風溫、流量要求對風門做適當調節;

              3. After the hot stove has finished heating preparation, it can supply heat to the grain drying tower, and turn on the cold and hot air fans in turn according to the operating rules. When using PLC automatic control system to control, we should pay attention to the starting sequence and interval of grain drying tower, and pay attention to the starting interval between fans and equipment when using manual control. Before starting the fan, we must close the inlet air door of the fan and open it after normal operation. We should adjust the air door properly according to different air temperature and flow requirements.

              4、注意掌握熱風爐引風機烘干熱風機風門開啟過程中的順序和程度。初次烘干供熱或較長時間停機后重新供熱,在所有應啟動的風機完成啟動后,首先打開熱風爐引風機風門;在熱風爐煙氣溫度達到300℃后,再逐步開啟糧食烘干塔熱風機風門,然后根據熱風溫度逐步加大熱風機的流量。此過程要保證熱風溫度始終不低于100℃,防止和減少因啟動過程熱風爐換熱器結垢或局部堵塞的現象產生;

              4, pay attention to the order and extent of the opening process of the hot air blower drier. After the first drying heating or a long period of shutdown, re-heating, after all the fans that should be started are started, the first step is to open the air door of the induced draft fan of the hot air stove; after the flue gas temperature of the hot air stove reaches 300 C, then gradually open the air door of the hot air fan of the grain drying tower, and then gradually increase the flow rate of the hot air fan according to the hot air temperature. This process should ensure that the hot air temperature is not less than 100 C, to prevent and reduce scaling or local blockage of the heat exchanger of the hot air stove during the start-up process.

              5、供熱趨于正常后要逐項檢查風機等運轉情況,適時觀察,記錄熱風爐、熱風、塔內糧層各點溫度變化,各主要控制點的電流變化,隨時分析、掌握塔內糧食的烘干狀態。

              5. After heating tends to be normal, we should check the operation of fans one by one, observe timely, record the temperature changes of hot stove, hot air and grain layer in the tower, and the current changes of main control points, and analyze and master the drying state of grain in the tower at any time.
