Technical Field

[0001] The utility model relates to the field of boilers, in particular to a boiler energy-saving pipeline circulation system. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and also has a small number of applications in industrial production.

[0003] During the use of the boiler, pipes are needed to transport the steam or hot water in the boiler. During the transportation process, the pipeline will produce a lot of heat loss due to the influence of the external environment, resulting in energy waste. For this reason, we propose a boiler energy-saving pipeline circulation system to solve the above problems. Utility Model Content
