Shutdown of the protective measures during the necessity and reasons boil boiler boilers, which during the shutdown, if you want to take some protective measures? Why boiler boil? In addition, the boiler thermostat should be how to set the start and stop temperature? All these questions and boiler-related products this important site, so the following, to explain in detail and answer, so, so that we have a correct understanding. 1. During the boiler shutdown, if you want to take some protective measures? Boiler, during which shutdown is to take some protective measures, because if you do not, then, the internal boiler corrosion of the metal surface will produce dissolved oxygen and temperature in an oxygen effect, especially in the superheater section . So, to take some precautions to avoid this problem inside the boiler, is the rusty metal corrosion. 2. boiler thermostat start and stop temperatures, how to set? Boiler thermostat, which is an important component, so its start and stop temperature setting, is an important work, and can not be careless treatment, so the following to briefly explain. Start temperature setting thermostat: the thermostat on the power cord plugged into an electrical outlet, the digital display face panel, press the start set the "+" key or the "-" key to start temperature set up. At this time, the temperature of first table shows the thermostat, the temperature is to start the circulation pump. Thermostat temperature setting stop: it is very simple, just stop setting the "+" key or the "-" key to stop the circulating pump set temperature, the temperature of the first table shows the , it is to stop the circulation pump temperature. 3. Why boiler will boil? Boil boiler, mainly by two reasons caused. First, if the boiler and radiator heat boil, then excessive heat boiler, then, should be pressure treated fire. Second, if the boiler boil, but the radiator normal, then the tube is connected to the boiler in question, then, should be to find and repair, to solve the problem.
When determining the boiler capacity, the number of shower, bath size, hot water tank capacity, bather flow, average water consumption, etc. will affect the boiler capacity. For different bathing environments, such as shower and baths, the calculation of boiler capacity is different. There is a reference formula here. If each shower head uses 300kg of hot water per hour (water temperature is 40°C), each shower head has a boiler capacity of D(t/h)=300*(40-cold water temperature)/60. *10^4. This data is for reference only and will involve more data in the actual selection.
