This article mainly introduce advantages of tunnel kiln waste heat recovery boiler.
1. Wide application range, internal combustion or external combustion type sintered brick tunnel kiln, super internal combustion or low calorific value raw materials can be used;
2. The system is highly automated and easy to operate;
3. High economic benefits, especially when the steam or hot water produced by the waste heat boiler is supplied to other production lines, the entire investment can be recovered within two years at most;
4. When the power generation plan is adopted, at least 80% of the power supply can be provided for the enterprise, and in the case of a power outage of the city power line, it can operate in an isolated grid to supply power to the production line normally to ensure the normal operation of the kiln roasting system equipment;
5. The boiler produces a large amount of steam, and the steam parameters can be set according to user requirements for pressure and temperature, usually within the range of 0.3～5.88MPa and 110～530℃;
6. The boiler is resistant to sulfur corrosion, oxygen corrosion, long life, and safe operation;
7. The boiler load adjustment range is wide, and it can be adjusted quickly and automatically within the range of 40% to 150% of the rated load;
8. Avoid compulsory smoking, over-temperature or excess heat affecting the temperature control, output and quality problems of the tunnel kiln;
9. The heat exchanger of the tunnel kiln waste heat boiler adopts a membrane wall structure, and the kiln has good sealing performance;
10. It can reduce the heat dissipation loss of the cooling zone of the tunnel kiln, lower the temperature of the product out of the kiln, and improve the labor environment of the workers.
