The working principle of the steam boiler is that the fuel burns to heat the water in the boiler, generating steam, which is transported to the production workshop for industrial production. In this process, condensate will be generated. If it is discharged, it will cause waste, so the boiler system will use condensate recovery. What are the methods for boiler condensate recovery, and why should condensate recovery be used? Yuanda Boiler Engineer Yang will answer for you.
1. The role of boiler condensate recovery
1. Increasing the boiler feed water temperature can greatly reduce fuel consumption, while increasing the boiler evaporation volume, which can better cope with changes in boiler load and reduce the use of standby boilers;
2. Condensate is the purest distilled water, does not contain solid components such as boiler scale, and if it is recycled, it can save a lot of boiler cleaning costs, water fees, water treatment fees and other corresponding costs;
3. Improving the quality of boiler feed water can improve the quality of steam, while reducing boiler emissions and saving energy loss;
4. The boiler feed water temperature is increased, the oxygen content in the water is reduced, and the corrosion of boilers, thermal engines and piping can be avoided. Extend the service life of equipment;
5. The boiler feed water temperature is increased, the temperature difference of the boiler air bag is reduced, the thermal expansion and contraction of the steel plate is reduced, and the service life of the boiler is extended;
6. Condensate recovery can reduce the amount of soft water supplied to the boiler, greatly reducing the water treatment costs inside and outside the furnace;
7. The temperature difference between feed water and boiler water is small, and the steam pressure is stable when the boiler is fed;
8. Condensate recycling, no steam pollution phenomenon and noise generated by the steam trap during draining, improve the working environment;
9. Reduce the emission of harmful pollutants such as CO, SO, and NO, in line with the national environmental protection industry policy;
2. Boiler condensate recovery method
1. The amount of condensate in the condensate recovery system must be accurately mastered. If the amount of condensate is not calculated correctly, the diameter of the condensate pipe will be too large or too small, and the boiler blowdown should be carried out regularly;
2. The pressure and temperature of the condensate must be correctly mastered. The method, equipment and pipe network of the recovery system are all related to the pressure and temperature of the condensate;
3. The selection of the steam trap in the condensate recovery system should also be paid attention to. Improper selection of the steam trap will affect the pressure and temperature of the condensate when it is used, and also affect the normal operation of the entire recovery system.
