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).

Hazard refaneri boiler chemeni highy scale chemical plants which boiler scale chemical plants What are the dangers? In the application process chemical plant boiler, for various reasons, the main boiler heating surface will produce a lot of fouling, and briefly describes the main hazards fouling. 1, the scale will reduce heat transfer efficiency boiler, heat boiler operating characteristics of the waste fuel boiler has a very close relationship. Internal inspection understood from the boiler, the boiler heating surface fouling occurs, the higher the heating temperature, the stronger the boiling, the more prone to fouling. Operation Practice of boilers and various data indicate that damage to the boiler fouling is mainly caused by the thermal conductivity, the thermal conductivity of steel is 1/5, will result in decreased formation of fouling of heat transfer efficiency. Thermal resistance is increased because the heat from fuel waste, low thermal efficiency. Studies have shown that analogy than 1mm, we should consume 3 to 5% of coal per scaling in the boiler. 2, the scale will shorten the life of the boiler and endanger the safe operation of the boiler from GB713-2014 "boiler and pressure vessel steel plate" inquiry found that the mechanical properties of steel will increase as the boiler temperature decreases. After the scale generated water present in the heating surface side, so that the resistance increases, the heat generated by the fuel combustion is not well transferred to the boiler water by the metal surface, resulting in the metal heating surface temperature increases overheating, reducing the structural strength of metal, prone smoke tube deformation on drum kits, tube wall area reduction and other hazards, shorten the life of the boiler and related components, a serious threat to the safe operation of the boiler. Additionally, high iron containing scale, the scale is easy to cause surface lower oxygen corrosion, scale formation and corrosion promoting the mutual drum, resulting in surface defects such as corrosion pits within the drum, the safe operation of the boiler hazard. 3, the scale will affect the water cycle boiler water circulation boiler operation of natural circulation and forced circulation divided two kinds. Boiler circulating water is balanced, whether it is rising or falling pipe tubes, should have sufficient cross-sectional area. Fouling not only the cross sectional area of ​​the waterwall tubes in the boiler waterwall tubes is reduced, but also because of a greater roughness and unevenness, the larger the flow resistance of the boiler heating surface fouling of the boiler water or steam will have some impact on the flow, the line is blocked when the scale, water circulation is stopped, the convection tubes by local temperature rise generates firing tube or tube rupture occurred partially vaporized, direct threat to the normal operation of the boiler.

Flue-gas stack - Wikipedia

The flue gas stacks are often quite tall, up to 400 metres (1300 feet) or more, so as to disperse the exhaust pollutants over a greater area and thereby reduce the concentration of the pollutants to the levels required by governmental environmental policy and environmental regulation.
