Atmospheric hot water boilers, which valves should be configured on them? Why must raw water be treated before entering the hot water boiler? And, through the specific model, what can be known? In addition, there are some other related questions. These are all about hot water boilers, and since it is one of the products of Wuxi Xineng Boiler, let’s give the specific answers below.
1.For atmospheric hot water boilers, which valves should be configured on them?
This question does not need to be considered by users but is a matter for the manufacturer to consider. Because when the atmospheric hot water boiler leaves the factory, it will be configured and corresponding instructions will also be provided. Generally speaking, most of them adopt one-time valve instruments.
2.Why must raw water be treated before entering the hot water boiler?
This is because if not, it will cause problems in the boiler. Because the hardness of raw water is relatively high, it will cause problems such as scale on the boiler tube walls, thereby affecting efficiency and other aspects. In addition, there are usually trace impurities in raw water. If it enters the interior of the boiler, it will cause harm. Therefore, raw water must be treated before entering the boiler.
3.For a 20-ton pressure-bearing coal-fired hot water boiler, if the return water pressure is slightly higher than the supply water pressure, what is the reason?
If the return water pressure of a 20-ton pressure-bearing coal-fired hot water boiler is slightly higher than the supply water pressure, the main reason is that there is resistance in the pipeline of the boiler, such as pipeline blockage. In addition, there are some other reasons. Therefore, it should be solved in time to avoid serious consequences and impacts.
4.For the hot water boiler DZW0.7-0.4/60/50-AII, through this representation, what can be known?
For the hot water boiler DZW0.7-0.4/60/50-AII, the “D” refers to the number of drums, which is a single drum. “Z” indicates that the layout of the drum is longitudinal, and “W” indicates that its combustion form is a reciprocating grate. Therefore, this is a single-drum longitudinal water-fire tube coal-fired hot water boiler, with a rated thermal power of 0.7WM, a rated pressure of 0.4MPa, a water outlet temperature of 60°C, and a return water temperature of 50°C.
