在電蒸汽鍋爐http://www.taodianbao.cn/鏈條爐中，由于燃料層是沿爐排長度分階段燃燒的，因此，各區(qū)段所需的空氣量亦不相同。如果不加控制分配向爐膛送入一次風，將使爐排兩頭的空氣量過多，造成爐膛內總的空氣過剩系數(shù)過大，而使爐膛溫度降低，排煙熱損失增加。為此把爐排下面的風室分成幾個風室。風室系用鋼板制作，各風室間互不相通，且都裝有調節(jié)擋板，運行時，按各段需要的空氣量進行分段送風，以改善空氣與燃燒的配合，降低排煙熱損失。
In electric steam boiler grate, the fuel layer along the length of the stages of combustion grate, and therefore, the amount of air required for each segment is not the same. If uncontrolled distribution of primary air into the furnace,make excessive amount of air at both ends of the grate, causing the furnace overall excess air ratio is too large, leaving the furnace temperature is reduced, increasing the heat losses. To this end the grate below the plenum chamber is divided into several wind. Air chamber system with steel production, between the air chamber are mutually unintelligible, and are equipped with adjustable baffle, running, according to the amount of air required for each segment to segment air, in order to improve co-ordination with the combustion air, reduce exhaust gas heat loss.
電蒸汽鍋爐送二次風的目的在于攪混燃燒著的氣流，延長其流程，加快流速，從而提高燃燒效率。另外，二次風還能將氣流中的部分焦炭吹落到爐排上。二次風一般是由風機將空氣送入架設在前拱上的鋼制風箱后，通過總的調節(jié)風板由風嘴吹入爐內。二次風要求有較高的風速，因此二次風機的風壓要比一次風機的高。二次風嘴一般布置在前后拱形成的喉部。爐拱、分段送風、二次風等改善燃燒工況的措施，除用于鏈條爐外，還可用于其他層燃爐上。
Electric steam boiler feed secondary air mix aimed burning air, extending their processes, accelerate the flow rate, thereby improving combustion efficiency. In addition, the secondary air flow can be blown into the part of the coke on the grate. After the secondary air is normally provided by the fan air into the front arch erected on steel bellows, by adjusting the total wind deflector wind blown into the furnace by mouth. Secondary air require a higher wind speeds,so the secondary fan than a fan of high pressure. Secondary air nozzles are generally arranged around the arch formed in the throat. Furnace arch, segmented air, secondary air and other measures to improve the combustion conditions, except for the grate, but also for the other layer burner.
當電蒸汽鍋爐內壓力接近工作壓力時，準備向外供汽，供汽前鍋內水位不宜超過正常水位，供汽時爐膛內燃燒穩(wěn)定。供汽時應將總汽閥微開啟，讓微量蒸汽進行暖管，同時將管路上的泄水閥開啟，泄出冷凝水，暖管時間根據(jù)管道長度 、直徑 、蒸汽溫度等情況決定。一般不少于是10分鐘，暖管時應注意管道的膨脹和管道 支架的情況，如發(fā)現(xiàn)有不正常情況應停止暖管，并解除故障和缺陷等管路已熱，管路冷凝水逐步減少后，方可全開總汽閥，開啟時宜緩慢進行，同時注意各部件有否特殊情況，如有應立即檢查，必要時停爐檢查。
When the internal electric steam boiler and pressure close to the operating pressure, ready for the steam out, for the steam pot before the water level should not exceed the normal water level, stable combustion in the furnace when the steam supply. When the total steam valve for steam micro open, allowing trace steam heating pipe, while the pipeline of the drain valve open, releasing the condensate, warm-time decisions based on the pipe length, diameter, steam temperature and other conditions. Is generally less than 10 minutes, the situation is heating pipe expansion and pipe bracket should pay attention to the pipe, if there is not a normal situation should stop heating pipe, and lift the faults and defects such as heat pipes have been gradually reducing condensate pipeline after before the total steam valve fully open, the open should be carried out slowly, while paying attention to each part has special circumstances,if any should immediately check, check shutdown when necessary.
電蒸汽鍋爐http://www.taodianbao.cn/運行時要求做到水位正常、蒸汽壓力穩(wěn)定，保持房的清潔，做好交接班工作，發(fā)揮人的因素第一，加強對各機械設備和儀表的觀察。確保安全可靠，防止事故發(fā)生，注意節(jié)約用煤，司爐工應定期總結經驗，不斷提高操作水平。
Required to achieve a normal level, the steam pressure is stable, keep the room clean and do shift work, the human factor plays first, to strengthen the observation of various machinery and equipment and instrumentation electric steam boiler running. Ensure safe and reliable, to prevent accidents, pay attention to save coal, fireman lessons regularly and continuously improve the operational level.
