Steam boilers are large-scale mechanical equipment with various forms, different specifications and different applicable conditions. The user is purchasing a steam boiler for the first time, but he does not know how to purchase it, and what is the basis and method of purchase. Xinli Boiler will briefly introduce you.
The following factors should be considered when purchasing a steam boiler: 1. Rated evaporation capacity of steam boiler
Rated evaporation is a proper term for steam boilers, which is the power of steam boilers. Generally, the power of a steam boiler is calculated by the rated evaporation capacity (unit: ton). Rated evaporation refers to the output of the boiler to heat water into steam per hour. This is the main parameter that we need to consider when we select the steam boiler. How to choose the most suitable rated evaporation? Generally, we must first calculate the steam we need per hour. If it is a hotel laundry room and hospital disinfection equipment, we can calculate the hourly requirement by looking at the parameters of the laundry room equipment. The steam parameters; if it is the steam used in the factory process, the steam required per hour can be calculated through the process flow. After calculating the amount of steam we need, we can choose a boiler. Generally, we need to choose a boiler whose rated evaporation capacity exceeds 20% of the calculated steam consumption. Because in the actual use process, there may be some situations where the steam consumption increases, or the steam boiler does not reach its ideal operating conditions. It should be noted that my country's steam boilers are calculated according to the rated pressure on the boiler to calculate the rated evaporation capacity, while some foreign steam boilers are based on the steam output under zero pressure. For example, the rated pressure of the Nuerte steam boiler is 1.0Mpa, and the steam temperature produced is 184°C, while the steam output at zero pressure refers to the steam output at 100°C. There is a big difference.
2. Rated pressure of steam boiler
The rated pressure refers to the pressure of the steam produced by the steam boiler. The temperature of steam produced at different pressures is different. The steam temperature of 1.0Mpa is 184°C, and the steam temperature of 1.2Mpa is 193°C. We need to choose a steam boiler that can reach the temperature we need according to our own usage.
3. Feed water temperature of steam boiler
Some boiler manufacturers often make fuss about the feed water temperature in order to increase their rated evaporation capacity. Some steam boiler manufacturers deliberately increase the feed water temperature to 90 ℃ or 100 ℃ or even higher when calculating the rated evaporation capacity. However, in actual use, such a high feed water temperature is not reached at all, and it will appear that the rated evaporation is not reached. The situation of steam production.
4. Thermal efficiency of steam boiler
The thermal efficiency of a steam boiler is the most important parameter that we need to consider when selecting a steam boiler. Because this is related to the operating cost in the future in use. The higher the thermal efficiency, the lower the future operating costs. For example, the inspection-free steam boiler newly developed by Nuerte now has a thermal efficiency that is about 10%-20% higher than that of a conventional steam boiler. In the actual operation process, it can save more than 100,000 yuan a year. Analysis of energy-saving benefits of Nuerte steam boilers.
5. Steam boiler outlet time
The steam output time of a steam boiler refers to the time it takes for the steam boiler to produce steam that meets the temperature requirements when it is turned on. The shorter this time is, the less energy is wasted. Generally, the steam output time of a steam boiler is about 20 minutes, and the Nuerte steam boiler only needs three minutes to produce steam. In addition to the benefits of energy saving, the fast steam generation speed can also improve the working efficiency of equipment that requires steam to operate.
