Low-nitrogen hot water boilers are widely used in many residential buildings, mainly for winter heating and hot water supply. The hot water boilers with low nitrogen technology have lower exhaust gas temperature and less harmful substances, which guarantee people's living environment and health. However, in order to further ensure the safety of its operation, the following points should be observed when operating low-nitrogen hot water boilers in residential areas.
First, we must control the water temperature and water speed
When the low-nitrogen hot water boiler for residential use begins to operate, the temperature inside the boiler and the components is the same as the ambient temperature. As the boiler burns, the temperature begins to rise; but because the boiler wall is thicker, the outside is The temperature rises more slowly, causing a temperature difference between the inner and outer walls. Moreover, the lower the thickness of the low-nitrogen boiler manufacturer, the greater the temperature difference between the inside and the outside will be. If the water temperature rises, the inside of the boiler may be deformed to form a crack. Therefore, the low-nitrogen boiler manufacturer emphasizes that in order to avoid this situation, the water supply speed and the water temperature should be controlled so that the temperature of the inner and outer walls of the boiler can be uniformly increased to protect the boiler from damage.
Second, we must control the speed of heating up
In the process of starting the combustion of the low-nitrogen hot water boiler, the internal pressure will increase as the temperature rises, so the two are simultaneously performed, and in the process of gradually increasing the pressure, not only the thick-walled steam drum The temperature of the inner and outer walls will produce a difference, and other parts will also generate thermal stress due to this change, which is unfavorable for the maintenance of low-nitrogen hot water boilers. Therefore, the professional low-nitrogen hot water boiler manufacturer - Fang Kuai Boiler reminds everyone that It must be controlled and the thermal stress should be reduced as much as possible to avoid adverse effects on critical components such as pressure pipes and flow orifices.
Third, we must properly adjust the speed of the boost
In the process of rising pressure inside the low-nitrogen boiler, it is necessary to go through several different stages, and the rising rate of the corresponding saturation temperature of the working medium is different for each certain unit of pressure, and the lower the pressure, the unit pressure is raised. The corresponding rate of increase in saturation temperature is greater and as the pressure increases, the saturation temperature of the water rises less and less. Therefore, the domestic professional low-nitrogen boiler manufacturer introduced that the boosting speed is very slow at the beginning, but when the pressure is relatively high, the speed of the boosting can be appropriately adjusted because the pressure rise and the temperature increase have mutual influence. Therefore, it is not possible to carry out the adjustment alone, and it is necessary to comprehensively consider the operation.
