The boiler should do a good job of cleaning every day, and the scale should be cleaned in time to avoid unnecessary losses.
Let's see what harm the boiler scale has. Causes the boiler metal heating surface to overheat, damages the boiler, shortens the service life. The fouling formed on the heating surface of the boiler, and the cooling of the metal wall was affected, which resulted in the rise of the wall temperature, the decrease of the mechanical strength of the metal material, the deformation of the heated surface, the bulging, the explosion of the tube, etc., and serious explosion even occurred. The imported gas indutrial steam boiler is damaged and the service life is affected.
2. Reduce boiler evaporation, reduce boiler thermal efficiency, waste fuel. The presence of boiler scale is equivalent to adding a layer of thermal resistance to the heating surface because The thermal conductivity of the scale is much lower than that of steel, which hinders the transfer of heat, makes the heat emitted from fuel combustion unable to transfer water effectively, the moisture does not measure the heat, and the heat on the flue gas side loses with the exhaust of smoke, so the output of the boiler should be reduced. A waste of fuel. According to statistics, a millimeter of scale wastes about 2% of fuel.
3. Destroy normal boiler water circulation, forced to stop furnace maintenance, increase maintenance costs. After scaling in boiler water pipe, the flow cross-section of boiler pipe decreases, and the flow power of water circulation is increased, even completely clogged when the water circulation is serious. Destroys the boiler normal water circulation, the pipe burns down, forced to shut down the furnace overhaul. Waste of manpower, material resources, Cause damage. In a word, the scale is harmful to the imported gas indutrial steam boiler, so that the boiler can not run safely and economically.
The explosion-proof door is overweight or the area of unloading pressure is insufficient; the design of exhaust temperature is not reasonable and so on. Poor management of boiler operation results in water shortage or fullness of boiler; poor management of water quality causes scaling of boiler; corrosion of metal heating surface caused by poor removal of oxygen; excessive alkalinity of boiler water caused by failure to discharge water in time; Bad atomization, incomplete combustion, instability or deviation of flame, failure of burner itself or failure of combustion system cause imported gas indutrial steam boiler to extinguish and so on. To sum up, improper design and installation of boiler and supporting process, poor operation and management will result in various accidents of boiler, which will bring loss to enterprise and employee's life and property. As long as we know and master If the law of hidden trouble of boiler accidents is strictly controlled, boiler design, boiler installation, boiler use and management, and continuous improvement and perfection of boiler management methods can be achieved, the occurrence of boiler accidents can be avoided by taking advantage of benefits and avoiding the occurrence of boiler accidents.
