Steam boilers have a long history of application in the heating field and mature technology. With advantages such as concentrated heat and flexible temperature regulation, they are widely used in industrial fields, urban centralized heating and other scenarios. The core logic is to heat water to a steam state by burning fuel, and then transport the steam to the terminal through a pipeline system. The heat is released through heat dissipation equipment (such as radiators and heat exchangers) to achieve space heating. The following aspects include application scenarios, core advantages, system composition, technical features, and trends in environmental protection and energy conservation.

1. Urban centralized heating system: As the core heat source for urban heating, steam boilers are usually built in heat source plants and transported to residential communities, office buildings, hospitals and other terminals through high-temperature and high-pressure steam pipelines. Steam is converted into hot water through heat exchangers at the community heat exchange station and then distributed to users’ homes (indirect heating). Or directly heat through steam radiators (for some industrial buildings/old buildings). It is suitable for densely populated urban areas, and the heating area of a single boiler can reach hundreds of thousands to millions of square meters.

2. Public buildings: Airports, railway stations, exhibition centers, university campuses, etc., need to quickly increase the indoor temperature and meet the uniform heating requirements of large Spaces. The high-temperature characteristics of steam boilers can achieve rapid temperature rise and also provide domestic hot water supply (such as hotels and hospitals).

3. Large industrial plants: Production workshops (especially process workshops with strict temperature requirements, such as chemical, electronic, and textile industries), office buildings, and employee dormitories. In some scenarios, heating and production steam (such as drying and disinfection) can be simultaneously met, achieving “one furnace for multiple uses”.

4. Heating in extremely cold regions
In areas where the winter temperature is below -20 ℃, the high temperature of steam (usually 100-200℃) can effectively overcome the heat loss in the low-temperature environment, ensuring the heat exchange efficiency of terminal heat dissipation equipment (such as radiators and floor heating), and avoiding the problem of “no heat at the far end”.
