Heat pipe waste heat boiler product features
◆ High heat transfer coefficient, good effect, compact equipment, small size and small installation space.
◆ According to the specific working conditions of the equipment, the surface temperature distribution of the heat transfer element can be changed by adjusting the heat exchange area between the hot and cold medium to avoid low temperature acid dew point corrosion.
◆ The two media realize the secondary wall heat transfer, the fluids are not separated from each other, and one or more heat pipes are damaged, which does not affect the continuous and stable operation of the equipment.
◆ The two media are all outside the heat pipe, single return operation, and the medium resistance is small.
◆ According to the characteristics of the flue gas, the medium flow rate is reasonably adjusted to achieve self-cleaning, non-scaling and no blockage when the medium passes through the surface of the heat pipe.
◆ The minimum temperature difference required for heat transfer between media is small, and low temperature recovery waste heat can be realized.
◆ The heat pipe single point is fixed on the inner cylinder wall (drum), freely suspended in the flue gas passage, thermal expansion and cold shrinkage are not restricted, no stress damage, long service life.

Installation of Heat pipe heat exchanger in Jinshan Petrochemical company. Heat pipe and efficient heat transfer technology combines advanced low temperature dew point corrosion technology to heat. The temperature of the flue gas is reduced to 100 °C-80 °C, and the waste heat of the flue gas is recovered to heat the combustion air. Increase the efficiency to over 93%.

Power plant energy conservation project - low temperature flue gas heat exchange system GGH

Low temperature flue gas heat exchange system GGH schematic The desulfurization system is the most mature with limestone desulfurization (FGD) wet technology and has the highest usage rate. The inlet flue temperature of the wet FGD is 80~90 °C, and the outlet flue temperature is generally 50~60 °C. The boiler smoke temperature is generally 120~140 °C, and some power plants use flue gas heat exchanger (GGH) to reduces the inlet flue temperature of the desulfurization system.

Separate high efficiency heat pipe GGH low temperature flue gas heat exchange system Integrated heat pipe high efficiency heat exchange system resistant to low temperature dew point corrosion can be used for flue gas desulfurization, or used in flue gas re-cooling system, to reduce the flue gas temperature to 80 ° C ~ 90 ° C. Improve desulfurization efficiency and reduce energy consumption and water consumption.
