watertube chain grate boiler south africa

Hot water watertube chain grate boiler south africa water temperature control range of PH value and importance of control of hot water boiler, which is one of the website products, but also a common and popular types of boilers, so the need for a comprehensive and in-depth understanding, so as to know what it is and how to the rational use and take advantage of in order to have a good use of effects in the use of the product, rather than wasted. 1. boiler water hot water boiler, which is the implementation of standards? This kind of boiler hot water boiler, furnace performance standards of its water is to GB / T1576-2008, but we also need to know that, in the use of this standard also applies to exports rated steam pressure less than 3.8MPa and a water as a medium and fixed soft drinks dual boiler steam boiler. Further, in the hot water boilers, hot water boilers and stationary pressure also applies pressure hot water boiler. 2. whether different types of hot water boilers correspond to different occasions?

The hot water boiler water temperature control range can reach the number? Which uses chemically treated outside the pot, then, whether there is water supply and total hardness requirements? Hot water boiler water temperature control range, the present, can be controlled within 5 degrees, to improve efficiency and the effect of hot water boiler. A boiler which, if a chemical treatment, then the outer pot, in the total hardness of the water supply is required, usually not be greater than the total hardness in claim feedwater 0.6mmol / L, and to strictly enforce this requirement, can not be sloppy. 4. Why PH value of the hot water boiler is very important? In addition, if there is hot water boiler heating area deciding factor? PH value of the hot water boiler is very important because if the boiler water PH value is too low, the water will increase the corrosive effect on steel, so rust corrosion inside the boiler, and the boiler water PH value is too high, steel alkaline the protective film is dissolved, so alkaline corrosion inside the boiler appears, therefore, is required PH value of water in the boiler control this range 10-12 to avoid these problems. Hot water boiler heating area, which is a decisive factor for the boiler itself, heating environment, pipeline and boiler manufacturers of these four.

Overpressure stop furnace and timely relief; low water level is not automatic replenishment, immediately replenishment manually; the (automatic or manual) stop switch transposed, and the relief after replenishment until normal reheating.

2, the control cabinet when overpressure occurs, phase, low water level, the high level alarm, press the mute button to check the cause of the malfunction and immediately removed; if the alarm is not more than 3 minutes in time, easy to burn bell.

3, in case when the phase indicated: A, to check whether the power supply phase. B, check the bell is burned out. C, check the contactor coil, a transformer, etc. is burned. After completion of the above problems troubleshooting timely replacement element, and the secondary fuse circuit, fault and inform the manufacturer in case of complex or repair guidance.

4, when the frequent replenishment, check whether the water supply pump check valve failure, fill the water tank upside down, shutdown should be promptly repaired or replaced.

5, regular (two weeks) to check the boiler water quality so that it meets the requirements, the need to frequently boiler blowdown.

6, on a regular basis (7-15 days) to check water level gauge scale and clean the electrode can be shutdown if necessary check.

Many food plants, hospitals, 10 tons of chemical used in small steam watertube chain grate boiler south africa water shortages, how to make correct and rapid emergency treatment is very important as it relates to operational efficiency and service life of the boiler.
