To extract heat from high-temperature flue gas at 700 degrees, is a heat pipe better or a conventional coil? By how much is the heat extraction efficiency of a heat pipe higher than that of a regular coil?
What are the components of the flue gas? Is the dust content high? Are there any acidic gases, and is water vapor present? Wait, only after knowing these issues can we decide whether to use heat pipes or shell and tube exchangers. Generally, using heat pipes increases the weight and size of the equipment, but by separating the gas and liquid sides, leaks will not cause acidic gases in the flue gas to cause corrosion. The advantage of tubular heat exchangers is material savings, but if leaks occur, the equipment will corrode rapidly and become unusable. It can also be designed in segments, with one part using heat pipes and another part using shell-and-tube design. Send over the smoke parameters and steam generation requirements. 506925142@qq.com
In fact, the flue gas is coke oven gas, containing coal tar and various impure gases; due to the high temperature, it is necessary to remove the heat as quickly as possible
One end is gas-liquid, and the other end is liquid-liquid.
