Rotary furnace manufacturers have been committed to the research and development and production of rotary furnaces for many years. A high-performance rotary furnace can be reflected in the use process, and of course, it is closely related to the operating standards of the operators. Today, the rotary furnace manufacturer will introduce the relevant knowledge of feeding the rotary furnace to everyone. In addition to controlling the temperature inside the furnace, the amount of feeding is important for the stability of the kiln operation and production quality Quantity also has a significant impact, so the correct method should be mastered when feeding
After the preparation work for feeding in the rotary furnace is completed, the feeding can be carried out. The initial feeding amount is set at about 1/3 of the normal production value. When the material enters the preheater, increase the speed of the high-temperature fan to maintain the negative pressure of the kiln head cover at around 50Pa and the negative pressure of the kiln tail at around 300Pa. Then, gradually add coal to the splitting furnace to over 1/3 of the normal value, and gradually adjust the opening of the third air brake plate to 80% of the normal opening, The kiln speed gradually increases to about 2/3 of the normal speed. During this process, attention should be paid to the coordination of air and coal materials. The temperature of the C5 discharge pipe should not exceed 900 ℃. When the C1 outlet temperature is lower than the normal temperature+50 ℃, the ignition chimney cap can be closed 2. The rotary furnace is prone to malfunctions after about half an hour of feeding. At this time, more attention should be paid to the temperature and pressure of the preheaters at all levels. If any errors are found, they should be confirmed and dealt with in a timely manner. At the same time, the opening of each fan of the grate cooler and the grate speed of each section of the grate bed should be adjusted according to the clinker discharge situation 3. After about half an hour of feeding, the system gradually enters a stable state (when the temperature of the decomposition furnace and kiln tail is stable, and the kiln current is stable and showing an upward trend, the production operation can be started), and the feeding amount can be gradually increased. Before increasing the feeding amount, the system air flow, coal feeding amount, and kiln speed should be increased. Before the feeding amount reaches 80% of the normal level, it can be increased by 5-10% of the normal amount each time, Faster production rate can be controlled with temperature control. After the temperature of the second and third air stabilizes to normal temperature, gradually increase the feeding amount (at a rate of 3-5% each time, of course, the mixing of air and coal materials must be achieved) to the normal value The rotary furnace manufacturer reminds that excessive or insufficient feeding can affect its normal operation stability. Therefore, before operating the kiln, it is necessary to understand its relevant instructions and master the correct feeding methods and skills
