The hot water boiler in boilers can be said to be a common and frequently used type. However, in terms of the learning and understanding of its specific knowledge, the degree is not comprehensive and sufficient enough, and there are still many deficiencies and shortcomings. Since this is the case and it is an important product, the following will continue this work so that everyone can reach the learning goals and requirements as soon as possible without leaving any regrets.
The inspection before the operation of the hot water boiler can be said to be very important and crucial because this will affect whether the boiler can be used safely and to avoid some dangers or accidents. Therefore, its implementation cannot be sloppy. In terms of specific contents, there are:
(1) The internal inspection of the hot water boiler and the inspection of its working preparations, whether they are fully and completely prepared.
(2) The inspection of the furnace and flue of the boiler to see if there is ash or debris. If there is, it should be removed in time. For the regulating doors of the air duct and flue, the main thing is to see if the gate is complete and tight, and whether the switch is flexible, etc.
(3) For the boiler accessories, they also need to be inspected to see if they are intact and can be used normally. In addition, for the instruments and control devices, it depends on whether they are complete and clean.
(4) For the automatic control system in the hot water boiler, as well as its accessory equipment and combustion equipment, a comprehensive inspection should be carried out to see if there are any problems. And whether its mechanical transmission system is normal.
(5) The heating surface in the boiler should be inspected carefully because it is very important and related to the heat transfer efficiency of the boiler.
In addition, it should be noted that in low-temperature hot water boilers, the system pressure is constant through the expansion tank, and the tank is generally installed on the circulation system. In high-temperature hot water heating systems, a nitrogen pressure stabilizing tank is usually used to achieve constant pressure. When all inspections of the hot water boiler are qualified, the protective cover can be installed, and then the trial operation can be carried out. At the same time, pay attention to whether there are any abnormalities or problems with the current, etc.
