What is the structure of finned tube radiator?
Based on the research and analysis of the heat exchange process of the 1MW solid electric heat storage heat exchange system, the minimum heat exchange temperature of the hot air is analyzed from the efficiency of the fan and the structure of the heat exchanger itself; when designing the heat exchanger, it is To ensure heat transfer, the highest outlet temperature parameter should be used as the benchmark; overall and parametric performance analysis should also be performed based on the heat exchanger design of the 1MW unit.

Do you know H-type finned tube radiator?
In my country, some coal-fired generating units have poor coal quality and high ash content. At the same time, the types of coal-fired coal are variable, which seriously affects the safe operation of thermal power units, especially the economizer tube bundle in the tail flue of the boiler. The flue gas temperature at the position is low, and the hardness of fly ash particles is high, so the problems of dust accumulation and wear are very serious. H-type finned tube radiator has good heat conduction characteristics, anti-corrosion characteristics and obvious anti-dust characteristics, and has been widely used in boiler economizers. For the structural optimization of H-shaped finned tubes, scholars at home and abroad have carried out extensive and in-depth research, including numerical simulation and experiments of H-shaped finned tubes. Thermal and resistance properties.
