What should be paid attention to when using a vacuum hot water boiler?

Winter is the peak period for the use of vacuum hot water boilers for heating. This type of boiler has the advantages of safety, stable operation and no noise, and can be used with confidence in places with a large flow of people; and Fangkuai boilers have also made technology for this type of boiler. Breakthrough and optimization, the boiler's operating efficiency is as high as 107%, the pollutant emission is less than 30mg/m³, it integrates energy saving and environmental protection, and the cost performance is very high. However, what issues should you pay attention to when you use the vacuum hot water boiler?

1. In vacuum hot water boiler equipment, the maximum temperature of hot water under negative pressure is about 93°C, and the maximum temperature of outlet water is about 80°C. Therefore, vacuum hot water boilers are commonly used in the field of civil heating and heating. The outlet water temperature of the boiler has higher requirements, and other types of boilers with higher discharge temperature can be selected.

2. The diameter of the heat exchanger of the vacuum hot water boiler is small, generally about 10mm. Although there is no fouling in the pipe, in order to prevent the system from clogging by impurities, a polluter or filter should be installed before the inlet of the boiler return pipe, and regular inspections and inspections should be carried out. Cleaning and maintenance.

3. When designing the vacuum hot water boiler structure, the boiler manufacturer will ensure that the working pressure of the system pressure can meet the requirements of the unit based on the system pressure, the parameters of the pressure unit and other parameters. During the installation and use of the boiler system, the pressure relief valve should be installed on the interface of the vacuum hot water boiler. The pressure set by the pressure relief valve must be less than the maximum allowable pressure of the device. The connection between the pressure relief valve and the unit It should not be assembled with the valve.
