Power Consumption of the Boiler Unit: The power consumption of gas modular boilers is extremely low, almost negligible. Single large boilers require forced and induced draft fans, which consume electricity. In contrast, modular boilers utilize atmospheric direct combustion, eliminating the need for a blower. The only electricity required by modular boilers is for ignition, and this consumption is minimal to the point of being negligible. If the electricity consumed by a single large boiler is converted into heat, the energy consumption of modular boilers is 1% lower than that of 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, footprint, and space utilization. It has been widely adopted in various new and renovated heating and hot water projects. Shaanxi Deli Energy Technology Co., Ltd., under the Fandel Boiler Factory, has developed a new environmentally friendly and energy-efficient gas modular boiler. This includes atmospheric direct-fired steel modular boilers, condensing gas modular boilers, and gas cast iron modular boilers. Production began in 2014, and by 2015, these boilers were widely deployed across various regions in Shaanxi, with sales extending as far as Xinjiang. The company boasts full independent research and development across the entire industry chain, direct sales from the manufacturer, government-recommended products, brand-name recognition, and comprehensive approvals for environmental impact assessments. It owns its land and facilities, with 30 years of manufacturing experience. Flue Gas Heat Loss: The boiler reduces heat loss by 75% compared to traditional single boilers. In conventional single large steel tube boilers, the flue gas temperature is typically maintained above 150°C to reduce low-temperature corrosion and condensation on the tail heating surfaces. However, 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 to 80°C). As a result, modular boilers achieve a 75% reduction in flue gas heat loss compared to traditional single boilers. Additionally, each modular boiler is equipped with a ventilation regulator. When a module is operating, the regulator opens, and when the module is not in use, it closes, preventing heat loss from residual heat in idle modules. Furthermore, the furnace walls of each modular boiler are insulated to minimize heat loss from the furnace. Actual tests have shown that modular boilers save 1% on fuel costs compared to single boilers.
