Автоматты түпкі үрлеу жүйесі

The formation of hard accumulation in өндірістік қазандар (stone and mud ) is caused by some impurities and corrosion ӨНІМДЕР contained in water. Examples of water impurities are; dissolved calcium, magnesium chloride, sulfate and silicon elements; Examples of corrosion ӨНІМДЕР include iron and copper. The water impurities in the өндірістік қазан consist of condensate leaks and өндірістік қазан feed water (make-up); Corrosion ӨНІМДЕР, as a result of corrosion, also comes from the condensate and feed water

Deposits cause a waste of fuel in the өндірістік қазан, a slight decrease in Өнімivity, and more importantly, overheating occurs metal annealing and pipe explosion. The өндірістік қазан zone where the accumulation causes the biggest problem is the evaporator pipes around the Оттықтар in the combustion chamber. The system that is used to prevent the problems caused by these hard accumulation compounds and to expurge hard materials from the өндірістік қазан is called Boiler Автоматты түпкі үрлеу жүйесіs

ACCUMULATION (STONE) TYPES

• Calcium carbonate (the most common type of stone), calcium sulfate, silica, phosphate stones, magnesium and magnesium stones, aluminum, iron oxides (usually in the өндірістік қазан and condensate line is the Өнім of corrosion)

ACCUMULATION EFFECTS

• Reduced thermal conductivity: stones are poor heat conductors and act as insulators as indicated by the various conductivity values. The resulting furring layer causes the reduction of steam generation. In addition, the resulting furring layer increases the fuel consumption and increases the unit cost of steam generation

Temperature build-up in the metal wall: As a stone-coated wall prevents heat transfer, the wall temperature rises. This is called overheating and the metal may lose some of its mechanical properties (elasticity, etc.). These cause local shape disturbances and cause pipe explosion
