Intelligent roaster roaster _ _ Yu Sheng Machinery supplied by Yu Sheng Machinery Co., Ltd. Xinxiang City. Road Zhiyuan, tempering forward. Xinxiang City, Yu Sheng Machinery Co., Ltd. (www.zgsyjx.com) strive to be and you win, symbiosis, strategic partners before the trip, the more determined to become industrial boilers and accessories of the most influential business, and you leap together to Success! Anti-boil a long-term shutdown, also known as the normal stop nursing, is expected to move according to prescribed procedures and cut off the water supply, stop feeding, the wind, the boiler stopped running process. In order to prevent the components shrink unevenly, you must press the following sequence: (1) gradually reduce the load, reducing the amount of coal supply surplus wind. When the load is stopped immediately stop coal, air, reducing the wind, turn off the main steam valve, open the trap superheater and economizer bypass flue. (2) to be fired Caesar do to stop the wind, close the flue baffle, remove ash, closed guard door, ash door, and pay attention to the water level. When the boiler pressure dropped to 0.1MPa (1kgf / c㎡), the opened air valve to protect the pot down to atmospheric pressure. (3) stop nursing six hours later, opened the flue damper, ash door, door, ventilation, and a small amount of water changes, 8-10 hours, change the water every two hours. When the boiler water temperature drops below 70 ℃, the release of all nursing water. Throughout stop nursing boiling furnace process, should always pay attention to the water level, so that it remains above the normal water line. Only maintain the security of the device after shutdown by the above method. Improve combustion efficiency roaster precautions required in the design: (1) air distribution system design is reasonable air distribution system is the key to whether the safe and stable operation of the furnace. Design, using isobaric bellows can get a good regulator with current sharing effect; the use of larger pitch, perforated cylindrical hood equilateral triangle and change the air distribution plate openings rate to ensure good flow of quality. Determination and selection of the various parts of the structure of the flow rate is a key dimension of the system design. (2) The main area of ??fluidized bed combustion of the fuel bed, sub-vertical segment and the basic segment. The cross-sectional area of ??the vertical section of the effective area of ??the air distribution plate are equal; the vertical section should have a certain height (- generally in the range of about 0.4m), to maintain a relatively high fluidizing speed to prevent the deposition of coarse bed material at the bottom. Vertical vertical section above in this paragraph for the diverging structures boiling furnace to reduce tobacco-speed Reduce the amount of fly ash out. (3) suspension suspension room for the main combustion chamber area of ??the fly ash combustibles, boiling at the upper fluidized bed furnace manufacturers, arch shaped refractory brick structure at the top of the formation. Suspension room for a big free space boiling furnace factory outlets, gas flow rate is low combustion temperatures are high, with Tangentially swirling secondary air is conducive to fine carbon particles burning ember. (4) U-shaped chamber burning ember burning ember in the furnace chamber to extend the residence time of the fly ash, to ensure high combustion efficiency, as well as the role of the separation of fly ash; In addition to the end portion of flue gas may pass into the air temperature regulation and control in order to meet the needs of users.
