Technical features of sintering machine HRSG:

Dual channel air intake technology: according to the characteristics of the waste heat flue gas of the sintering annular cooler, the flue gas of different temperatures enters the boiler by two channels, to realize the cascade utilization of flue gas and improve the utilization rate of flue gas.

Double pressure boiler technology: HRSG has two different pressure and temperature steam parameters, and the boiler has its own deaerator to achieve cascade recovery of energy and improve energy recovery utilization rate.

Full natural circulation waste heat boiler technology: the waste heat boiler adopts the full natural circulation evaporation system, no extra circulating pump, to improve the integrated utilization rate and reduce the intermediate equipment and fault point.

Pure low temperature flue gas waste heat recovery technology without supplementary firing: the waste heat flue gas of sintering annular cooler is the pure low temperature flue gas of 250~450℃, the waste heat boiler does not need supplementary firing, can realize pure low temperature waste heat recovery.

Meet the requirements of irregular change of the annular cooler waste heat flue gas, quick start and stop.

All heating surfaces adopt the tube box structure to ensure the quality and convenient installation and shorten the installation period.

All heating surfaces use spiral fin tubes, which is suitable for the low temperature and large flow of annular cooler waste heat flue gas.

Full drain structure, the boiler drainage is convenient and thorough.
