WYRG-XF type heat recovery device for flue gas heat recovery and use of waste heat boiler blast heating equipment. During installation, the smoke box part WYRG-XF type heat recovery device on the device through the flue flange (corresponding inlet flange of smoke has been noted in the body of the device) is connected near the boiler flue; WYRG-XF cold bellows-type heat recovery section of the inlet and the blower is connected to the hot air out (already indicate the appropriate cold into the hot air out of the body flange on the device) and the boiler is connected to the inlet plenum. Have the following precautions during installation: 1, the installation process, must strictly follow each flange opening marked on the device corresponds to this connection. 2, the installation process, connect the flue and the device channel blower and the connection with the boiler should be avoided right angle connector, corner must be adapted to the actual situation of the elbow angle. 3, must ensure that the device must be level with the ground after installation. Heat pipe heat transfer element is a high-heat performance. It happened through the liquid phase transition in a closed tube heat transfer, small internal resistance, good isothermal performance characteristics, in particular in: 1, high heat pipe heat transfer efficiency, small heat pipe in addition to the phase change heat transfer outside, When the heat pipe heat exchanger ribs on both sides of a fluid, heat transfer enhancement. Under the same heat load, the number of tubes can be reduced, the flow area can be expanded, the flow rate can be reduced, greatly reducing wear and improve the life of the heat exchanger heat pipe heat exchanger hot and cold fluids pure countercurrent arrangement, smoke, air flow uniformity, janitor thermal coefficient, small size, light weight, easy layout. 2, heat pipe heat exchanger has good corrosion resistance due to the heat transfer tubes by liquid phase transition, the wall temperature, isotherm performance, designed so that the wall temperature to avoid the dew point temperature of flue gas, flue gas heat pipe is not flushing , condensation, flue gas sulfur does not overflow, but discharged with the flue gas, the heat pipes, tanks and piping will not corrode. 3, heat pipe heat exchanger has a strong prevention fouling, plugging ash capacity due to the dew point to avoid the smoke, so that dust is not easy to bond to the fins and the wall. Adjusting the design of good smoke and air side road ratio, adjust the flow rate, can be beneficial self cleaning. At the same time will produce heat pipe heat conduction from the vibration, the ash is not easy to adhere to the wall and fins, and thus will not block ash. 4, long service life of the heat pipe heat recovery device life over 10 years, does not ring shadow operates waste heat recovery heat pipe when a single failure, the heat pipe removable and exchangeable.
