For users who need to use industrial boilers, how to determine the capacity of the boiler when purchasing a boiler is an important issue. Waste of resource cost. The technical engineers of Zhengzhou Fangkuai Boiler Factory with many years of experience have summarized the following methods for determining the capacity and number of boilers in the selection of industrial boilers for your reference.
First of all, the output or capacity of the boiler should be determined according to the steam consumption or heating area in the production process and the heating required for domestic hot water. First, the user should find out the total load range. The second is the peak situation, including the duration of the peak load and the frequency of the peak, which is the periodicity of the peak, such as the frequency of the peak each month, the difference between each week, each month, and winter and summer. After finding out the total load demand and peak, you can consider the choice of equipment capacity and quantity. When choosing, also consider the issue of emergency shutdown reserve. Generally speaking, the spare capacity refers to a spare boiler. This needs to be determined according to the importance of the user. If there are high requirements for the continuity of production and use, the issue of spare equipment must be seriously considered.
The economic load of the boiler is generally more than 75% of the rated load, so the actual load of the boiler in use should always be more than 50% of the rated load of the unit itself, that is to say, the equipment provided by the manufacturer should be 50%-100% of the rated output Maintain stability and efficiency between. In the past, users often purchased too much surplus for safety, resulting in long-term low-load operation of the equipment, which was very uneconomical. Generally, for boiler houses with a total capacity of 8 tons/hour or thermal power plants above 6 MW, it is more appropriate to choose three sets of equipment capacity. Because winter and summer are different, we can choose equipment with different output. However, considering the operation, maintenance, and management of a newly-built boiler room, it is convenient and economical to choose equipment with the same output. In this way, the layout of auxiliary equipment in the boiler room can be arranged reasonably. If you consider the peaks and valleys, there is a big difference between winter and summer, you can also choose two large equipment and one small equipment. According to the situation, it is necessary to build a new boiler room and choose more than three equipments, but not too many. Instead of using multiple sets of equipment, it is better to choose a larger capacity equipment. Under current domestic equipment quality conditions, it is necessary to consider standby units.
So it is recommended that if you have a boiler demand, it is better to carefully select the boiler manufacturer. There are many boiler manufacturers, but not many with good qualifications. There are only a few that can have A-grade boiler qualifications. For example, Fangkuai Boiler has A-grade boiler manufacturing qualification and first-grade boiler installation qualification. Focusing on condensing boilers for more than 20 years, the domestic condensing boiler leader. And the boilers of large factories are guaranteed and the prices are low. For example, the common natural gas boilers are quoted, and the factory sends directly with high quality and low price. The thermal efficiency is high, and the heating area is larger than that of general boiler manufacturers. Some common boiler problems can be avoided, and the cost of gas boilers is reduced, corresponding to the increase in the cost performance of boilers.
