Gas oil hot water heating boilers selection
What should you pay attention to when selecting some gas oil hot water heating boilers?
1. How to determine the tonnage and number of boilers
In response to this problem, the total heat demand is first calculated based on the heating area and the amount of domestic hot water. At the same time, in the process of calculation, it is also necessary to take into account the architectural characteristics of the heating area, the characteristics of the temperature, the peak period of the water supply and heating, and other external factors, so as to adapt to local conditions. Then, after the comprehensive evaluation, you can consider the problem of the tonnage and the number of the furnace. Then, how to choose, this requires the previous analysis results to analyze the characteristics of the boiler used in the project, and also to understand the actual boiler. Operational efficiency, as well as whether the tonnage and heat supply match the actual needs of the customer site.
2. When choosing some gas oil heating boilers, is it a steam boiler or a hot water boiler? Through the application analysis of many enterprises, a simple comparison between the two will find that the hot water boiler will be more energy efficient than the steam boiler. Therefore, if the project has energy saving requirements, it is recommended to use a hot water boiler. Of course, some hotels, hospitals and other places that require both hot water and steam need to be determined according to the actual situation. If the heating system uses a large amount of hot water and requires a small amount of steam, it is recommended to install a small steam boiler or steam generator in addition to the hot water boiler to meet a small amount of steam demand. For example, the steam demand of a hospital or a star hotel does not exceed 30% of the total heat demand, and according to the actual experience, the steam boiler has a large loss of its own efficiency in addition to the problem of low efficiency in the low-load operation state. Larger, the ultimate energy utilization rate is generally only about 60%, and energy waste is serious.
