The modular design of gas-fired boilers, combined with the coordination and control of intelligent software, easily achieves flexible, efficient, and economical operation of boiler units. For example, in a heating station with a heating area of 25,000 m², 12–18 modular boilers are used to provide the heat source. Under manual control, the minimum output adjustment accuracy is 8.3%, with a temperature adjustment range of 2.0°C. Under automated software control, the minimum output adjustment accuracy improves to 4.0%, with a temperature adjustment range of 0.5°C. This clearly demonstrates the significant advantages of gas modular boiler units in improving heating quality, reducing operating costs, and lowering energy consumption. Regardless of seasonal conditions, each operating modular boiler can run at full load, while non-operating boilers consume no energy, ensuring that the entire boiler unit operates at high efficiency. According to actual customer statistics, the combination of modular boilers with an automated control system significantly reduces excess heat loss, resulting in an overall energy savings of 15.4%. **Power consumption of the boiler unit:** The electricity consumption of gas modular boilers is extremely low, almost negligible. Single large boilers require forced-draft and induced-draft fans, which consume electricity. In contrast, modular boilers use atmospheric combustion and do not require forced-draft fans. The only electricity consumed by modular boilers is during ignition, which is minimal. If the electricity consumption of a single large boiler is converted into heat energy, modular boilers reduce energy consumption by 1% compared to traditional boilers. In summary, the modular boiler series represents a breakthrough in design philosophy and form compared to traditional boilers. This series offers unparalleled advantages in environmental protection, energy efficiency, safety, automation, lifespan, installation, power consumption, capacity expansion, and space requirements. It has been widely adopted in various new and renovated heating and hot water projects. **Flue gas heat loss:** Boilers in this series reduce flue gas heat loss by 75% compared to traditional single boilers. To mitigate low-temperature corrosion and condensation on the tail heating surfaces, single large steel-tube boilers typically maintain flue gas temperatures above 150°C. In contrast, modular boilers use corrosion-resistant cast iron materials for their heating surfaces, providing strong resistance to corrosion. Through optimized heat transfer design, the flue gas temperature is reduced to below 100°C (60°C–80°C). As a result, modular boilers reduce flue gas heat loss by 75% compared to traditional single boilers. Additionally, each modular boiler is equipped with a ventilation regulator. When a module is operating, the ventilation regulator opens, and when the module is not in use, it closes, preventing heat loss from residual heat in idle modules. Furthermore, each modular boiler’s furnace wall is insulated to minimize heat loss from the combustion chamber. Actual measurements show that modular boilers save 1% on fuel costs compared to single boilers.
