Stainless Steel Waste Heat Eco-friendly Flue Gas Cooler for Industry
Product Information
1. Before designing this kind of equipment, it is necessary to know the nature of the gases to be cooled and their dust content.
2. The purpose of all that is to design an equipment free of important fouling which would force to make cleaning works more frequently than wanted.
3. We must have in mind as well the availability to detach the dust from the gaseous stream containing it in all those areas where there is a bend or some enlarging in the pass section, which forces to include in the design some systems for dust collection and removal, to allow the correct heat exchange.
4. Working principle of a flue-gases cooler is the same as in the above-described equipment, but the aim in this case is to cool a primary fluid, not to get a thermal profit by heating a secondary fluid.
5. These equipment are usually installed as the previous step to a flue-gases cleaning, to avoid the gases from reaching the cleaning systems at too high temperatures. This means an alternative to the dilution with air, which would imply an over-sizing of the mentioned systems.
Efficiency
| 1. Flue gas condensation may cause the heat recovered to exceed the Lower Heating Value of the input fuel, and thus an efficiency greater than 100%. |
2. Since historically most combustion processes have not condensed the fuel, usual efficiency calculations assume the combustion products are not condensed. |
3. This assumption is implicit when basing calculations on the Lower Heating Value. |
| 4. A more rigorous approach would be to base efficiency calculations on the Higher Heating Value, which typically results in efficiencies less than 100%.[citation needed] |
| 5. Should the flue gases be cooled below 25 °C (77 °F), even efficiencies based on the Higher Heating Value may exceed 100%, since typical heating value definitions assume that all heat is released when combustion products are cooled to somewhere between 15.56 °C (60.01 °F) and 25 °C (77 °F). |

Features
In traditional boiler, fuel after the boiler combustion, exhaust smoke temperature is relatively high, the flue gas water vapor is still in the gaseous state, will take a lot of heat. In all kinds of fossil fuels, hydrogen content in natural gas is highest, the quality percentage of hydrogen is about 20% to 25%, as a result, the smoke contains large amounts of water vapor, according to estimates, burning 1 square meters of natural gas to take away the heat of the steam produced paper of 4000 kj, which is about more than 10% of the gross calorific value.
