Large Central Heating Boiler-Circulating Fluidized Bed Boiler

Large centralized heating boilers generally refer to heating boilers with heating area of more than 300,000 square meters. For boilers with heating area of less than 300,000 square meters, users mostly use natural gas hot water boilers. What type of boiler is suitable for large central heating?

1. Heating Area and Boiler Size

In theory, the heating capacity of 0.7MW (1 ton) hot water boilers is 10,000 square meters. Considering the heat loss and other factors, when considering the size of the boiler, the heating area of a 1 ton hot water boiler can be 6000-8000 square meters, and the size of the boiler should be appropriately larger than the heating area to withstand the extreme cold weather. It can be seen from the above that 300,000 square meters of heating area need about 50 tons of boilers.

2. Choosing Which Type of Hot Water Boiler

Generally, for large-scale central heating projects, our company recommends circulating fluidized bed boilers to you, because:

1) Boiler capacity is large, mostly used in urban, community and other large-scale centralized heating projects. The capacity of fluidized bed boiler in ZOZEN boiler is 10-410 tons, which can meet the needs of various large-scale heating projects.

2) High efficiency and energy saving. The combustion characteristics of circulating fluidized bed boilers are high thermal efficiency. The thermal efficiency of ZOZEN circulating fluidized bed boilers can be up to 90%.

3) Coal has wide adaptability and full combustion, which can greatly reduce the operation cost of boilers. After all, the domestic cities are gradually phasing out coal-fired boilers below 35 tons, but CFB boilers still do not fail because of their advantages of high efficiency and low emission.
