Waste heat boiler flue gas heat is recovered for energy, it is also known as flue gas waste heat boilers. I produced the waste heat boiler for heat pipe heat exchanger components, the heat transfer efficiency up to 98%, which is unmatched by ordinary heat. Heat pipe heat recovery unit is small, just an ordinary heat exchanger 1/3. It works as follows: the left is the flue gas channel, the right to clean air (water or other media) channels, the middle partition without disturbing each other apart. High temperature flue gas emissions from left channel, when the high temperature flue gas emissions heat pipe erosion, when the flue gas temperature> 30 ℃, the heat pipe is activated automatically transfer heat to the right, then left endothermic heat pipe, high temperature gas flows through the heat pipe after temperature drop, heat conduction and the heat absorbed by the tube to the right. Often 温清洁 air (or other aqueous medium) under the effect of the blower, flow in opposite directions along the right channel erosion heat pipe, then the right side of the exothermic heat pipe, the clean air (or other aqueous medium) is heated, after the air flows through the heat pipe temperature. HRSG / performance characteristics of waste heat boiler: 1, high security and reliability: the conventional heat transfer equipment are generally partitions heat, hot and cold fluid on each side wall of the flow, such as a wall or a wall there leak, it will result in lost production. HRSG is secondary partitions heat, that heat to be transferred Ling fluid through the heat pipe evaporator and condenser section of wall to wall. 2, waste heat boiler heat transfer efficiency, energy-saving effect is remarkable. 3, waste heat boiler has good corrosion resistance of the heat pipe wall temperature can be adjusted by an appropriate transformation of the heat pipe heat pipe wall temperature adjustment above the dew point of the cryogenic fluid, thereby preventing the dew point corrosion, ensure long-term operation of the equipment. Due to the dew point to avoid the smoke, so that dust is not easy to bond on the ribs and the wall. At the same time will produce heat pipe thermal self-vibration, the ash is not easy to stick to the wall and fins, and thus will not block ash. 4, installation and structural layout flexibility: install waste heat boiler system without changing the original process, design and location of the layout is very flexible and can adapt to a variety of complex applications. 5, long life: life in more than 10 years, a single removable heat pipe replacement, simple and low maintenance costs. 6, the payback period is short: usually six months to a year all the investment can be recovered.
