Modular boilers refer to the connection of multiple boilers through joint control, according to the re-set heating demand curve and other parameters, and referring to the indoor and outdoor temperature difference, the system can carry out the number of boilers on/off intelligently, to realize the automatic adjustment operation mode. Modular boilers are widely used in many areas such as residential district heating and hot water supply, as well as industrial enterprise production. After two or more boilers are jointly controlled, the number of running boilers can be adjusted according to user needs. For example, if the residential building needs to adjust the supply temperature according to the seasons to adjust the number of running boilers, the industrial enterprises will adjust the number of running boilers depending on the quarterly workload and other factors.
The concept of "module" is equivalent to splitting a single large boiler into multiple small boilers, and achieving the required amount of steam by simple parallel combination in quantity. In this way, the boilers have many advantages.
1. Every boiler is standby for each other, and the stability and safety of operation will be improved. When an unexpected failure occurs in a boiler, other boilers can immediately replace to minimize adverse effects.
2. More savings in operating costs. The numbers of running boilers can be increased or decreased at any time according to the users needs, and can be flexibly adjusted to save fuel consumption costs.
3. The requirements for the infrastructure of the boiler house are not high, and the capital construction costs are greatly reduced. Many joint-controlled boilers generally use small boilers with little volume. The requirements for the boiler room are not high, and can be adjusted according to the size of the boiler room. Therefore, this type of modular boilers is more suitable for boiler reconstruction and expansion projects.
FANGKUAI Boiler owns a series of commercial small boilers such as "Thalia", "Herold" and "Valarie", which can be flexibly matched according to user needs. If you are interested in modular boilers or have any doubts, you can contact us directly through the contact information on the website, and you are welcome to visit our factory at any time.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025.
