The main operational principle of boiler is the water that the waste heat in the heat energy or industrial production discharged after a kind of utilization fuel combustion is passed in container, the heat power equipment of temperature or certain pressure steam required for reaching water.Boiler is carried out simultaneously at " pot " with " stove " two parts, and water enters after boiler, the heat transfer feedwater that boiler heating surface will absorb in boiler circuit, water is heated into the hot water or generation steam of uniform temperature and pressure, is brought out application.In combustion apparatus part, heat is constantly released in fuel combustion, and the high-temperature flue gas for producing that burn transfer heat to boiler heating surface by the propagation of heat, and self-temperature is gradually reduced, and is finally discharged by chimney.
Boiler failure reason in production and living is varied, but general boiler failure is typically relevant with the raw water quality of supply boiler, dissolved oxygen especially in raw water water is exceeded, dissolved oxygen in boiler feedwater turns into the depolarizing agent of cathode process in corrosion reaction, causes steel systeming equipment that oxygen corrosion occurs.Because the final product for corroding is the oxide of iron, therefore the further deterioration of boiler feedwater quality can be caused again.
At present, the deaeration plant of the raw water shortcomings such as poor, complex operation, deoxygenation high cost, maintenance inconvenience that also there is deaerating effect.
