Maintenance of the boiler plant food during the maintenance shutdown has deactivated which is to prevent boiler corrosion. Since boiler shutdown, a large boiler humidity, poor ventilation, if long-term in a wet state, oxygen in the air with the metal heating surface of the wet complete contact, the inner surface layer of brown rust generated; in addition, often the heat receiving surface of the gas side accumulating ash particles during operation, after the shutdown in the humid environment, will cause corrosion of metals. In the boiler shutdown process, the main reason is the presence of moisture and corrosion of metal surfaces of the air. Thus, as long as the metal surface or a metal surface with dry air (oxygen) isolation, can effectively prevent corrosion. The length of the parking time, there are packing, Paul dry, wet security, ventilation PROTECTION. 1, pressure maintenance Pressure maintenance is suitable for up to one week shutdown of the boiler. The residue pot pressure 0.05 ~ 0.1MPa, temperature slightly above 100 ℃. Boiler pressure and temperature to maintain regular methods using steam heating the water adjacent to the boiler, a heating boiler or intermittently. 2. Dry Dry care maintenance is a method to protect the desiccant into the pot and in the furnace. Its purpose is to keep no water jug. The utility model is suitable for long-term or seasonal shutdown boiler heating boiler. Open manholes and hand holes, the header and the drum-dried. When wet boiler room, with appropriate use of the furnace heat or light burning wood, so that the furnace, the furnace wall flue drying. After drying the boiler is cooled, the opening and tray formulated desiccant tube is placed in the pot, and a collecting box grate, then tightly closes the inlet aperture, and a valve connected to the hand hole to prevent air from entering. For some Mifengbuyan valves, plug board should be increased.
Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam boiler steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Ovens: The purpose is to oven just completed construction within the furnace refractory lining, wall, chimney, brick chimney where the smoke channels are baked. Refractory lining, flue, chimney large water wet, must be dried by baking it gradually, fireclay mortar joint strength is increased, when the oven is generally employed waste wood, dry branches, bark baking as a fuel but nails should be removed. Baking should adopt slow roasted slow fire, gradually furnace, flue, chimney evaporation drying. Avoid the drying fire emergency water volume surge abruptly evaporated, water vapor and flue gas emissions cause untimely furnace wall, high flue deformed by the internal pressure, fracture or even collapse. Therefore, it must be baked cook work. For each year into the winter heating boiler module operation should be carried out before starting work oven into operation. To ward off moisture inside the furnace and the chimney flue.
Vietnam is a traditional agricultural country, and 75% of the total population is agricultural population. Therefore, Vietnam is rich in crops such as coconut, palm, rice, corn and so on, and it can supply large quantity biomass energy to the wood waste water tube boiler.
