1, due to the lower part of the drum riser arranged in rows and covered with fire-resistant bottom layer, eliminating the dead zone at the bottom of the drum, so that the sludge is not easy deposition, the high temperature zone can get a good drum cooled to prevent the lower drum drum kits.
2, the use of fire and water pipe installation, access to the enhanced heat transfer effect, to temperature and pressure and fast to improve the thermal efficiency of the boiler.
3, compact structure, small size, saving boiler room investment in infrastructure.
4, stable operation, easy adjustment, output foot, high thermal efficiency.
5, quick type factory boiler to the scene, only to install utilities and pipelines can be used.
6, the boiler has some dust effect. The boiler exhaust dust concentrations at below standard, ensuring the index boiler soot emissions meet national environmental regulations.
