Main purpose
The waste heat recovery system developed by our company has broken through the technical bottleneck of traditional industrial waste heat boilers, adopting new materials for heat exchange equipment, developing high-strength heat exchange components and optimizing heat exchange devices, achieving the goals of high energy recovery rate, stable operation, low investment, low operating cost, and strong applicability. The equipment structure of this project is compact and occupies a small area, which can be used to match new projects or easily used for the renovation of old projects. The productization of the project will significantly reduce the emissions of pollutants from flue gas in China's industrial production, and contribute to the purification of the country's atmosphere.
The various sensible heat emissions emitted by various industries during production or equipment operation, if directly discharged into the atmosphere, will cause a large amount of thermal energy loss. Our company has successfully developed a heat pipe waste heat boiler using heat pipe technology, which recovers the sensible heat from low-temperature exhaust gas into low-pressure saturated steam for production and daily use, achieving the dual goals of energy conservation, consumption reduction, and environmental protection.
Structure and characteristics
High heat transfer coefficient, good effect, compact equipment, small volume, and small installation space.
By adjusting the heat transfer area between the cold and hot media according to the specific operating conditions of the equipment, the surface temperature distribution of the heat transfer elements can be changed, successfully avoiding low-temperature acid dew point corrosion.
Two types of media are used to achieve secondary wall heat transfer, and the fluids are not in series with each other. If one or more heat pipes are damaged, it does not affect the continuous and stable operation of the equipment.
Both media pass through the outside of the heat pipe, with a single return operation and low medium resistance.
According to the characteristics of the flue gas, adjust the medium flow rate reasonably to achieve self cleaning, no scaling, and no blockage of the medium when passing through the surface of the heat pipe. The minimum temperature difference required for heat transfer between media is small, which can achieve low-temperature recovery of waste heat.
The heat pipe is fixed at a single point on the inner cylinder wall (steam drum) and freely suspended in the flue gas channel, with unrestricted thermal expansion and contraction, no stress damage, and a long service life.
