Description
Technical Field
[0001] The present application relates to the technical field of steam generators, and in particular to a high-efficiency heat exchange coil and a steam generator thereof. Background Art
[0002] Steam generator, also called steam heat source machine, is a mechanical equipment that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. It is now widely used in power generation, heating, chemical industry, food processing and other industries.
[0003] The existing steam generator mainly consists of an evaporation coil, a burner, a heat exchange chamber, and an exhaust system. When working, water flows into the evaporation coil inside the heat exchange chamber, and the high-temperature flue gas is passed into the heat exchange chamber through the burner to exchange heat with the water flowing in the evaporation coil, so that the water vapor after heating and evaporation is output from the other end of the evaporation coil, and the flue gas after combustion is sent out from the exhaust port on one side of the heat exchange chamber.
[0004] However, due to the limitation of the inner diameter of the evaporator coil, it is difficult to increase the single evaporation amount of water in the heat exchange chamber. If the single evaporation amount is increased simply by increasing the inner diameter of the evaporator coil, the single water intake amount needs to be increased accordingly, which will also lead to an increase in water use costs, which is not conducive to the company's cost control. Utility Model Content
[0005] In order to effectively increase the single evaporation amount of water in the existing heat exchange chamber while reducing the water cost, the present application provides a high-efficiency heat exchange coil and a steam generator thereof.

At the same time, the water vapor obtained after vaporization is sent out from the third guide member located between the first guide member and the second guide member, which can also effectively keep the water vapor inside the third guide member warm, and reduce the phenomenon of water vapor being liquefied when it flows inside the third guide member.
