During the shutdown boiler heating surface surface absorbs moisture from the air to form water film. Water film in the chemical reaction of oxygen and iron rust is generated, the boiler from corrosion. After being put into operation boiler corrosion, rust and corrosion at high temperatures will increase the depth and expand the area of ??arts boiler corrosion and iron skin constantly peeling up of leakage, resulting in shortening the life of the boiler, or even serious explosion. Boiler shutdown maintenance work is to try to reduce air pot of water leakage into the outside world and prevent oxygen, or an attempt to reduce the oxygen in contact with the boiler pressure parts, so that the boiler pressure parts to avoid corrosion or mitigate corrosion. Thermal maintenance methods, wet maintenance, dry maintenance. Thermal shutdown maintenance suitable for hot spare; suitable for short-term maintenance of wet deactivation small boilers; dry law applies to any type of long-term disabled boiler. Current maintenance in wet and dry most widely used scale for oil boiler running the danger is obvious: (1) a waste of fuel. When the inner wall of the heating surface bonding 1mm scale, it is necessary to consume about 4% of fuel; bonding 2 mm scale, multi-fuel consumption of about 7.5%. (2) reduce the boiler output. Formation of scale, it will affect the heat transfer effect of the boiler, the boiler will inevitably reduce output. (3) caused by boiler accident. After generating scale boiler heating surface, to maintain normal output of the boiler, had to increase fuel consumption, while the metal is heated wall temperature will increase 2 million molten Arts boiler boiler drum kits will happen then, bending arts boiler 9000000 molten salt boilers, burst pipes, the explosion will occur in severe cases. Also in the boiler pipes, clogged pipes due to scale arts molten boiler boiler 6 million, affecting the water cycle, which beaker pipes. (4) waste a lot of steel. Because of the scale of production, will affect the heat transfer effect of the boiler, the boiler output reduced, so that the decline in the utilization of steel boiler. Arts boiler 2,000,000 molten salt boilers, boiler Arts (certified), provided by the Hebei Arts Arts boiler boiler limited liability company. Hebei Arts boiler limited liability company (www.yi-neng.cn) Hebei Cangzhou, a leader in industrial boilers and accessories over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Boiler leadership in the arts with the staff warmly welcome all inquiries negotiations to create arts boiler a better future.
