1. The drum consists of arched tube sheet and spirally corrugated tube, which makes the shell change from the quasi-rigid into quasi-elastic, so as to prevent the tube sheet from cracking.
The optimal design of the spirally corrugated tube strengthens the heat transfer, speeds up temperature rapidly and enhances the boiler steam rate.
6. With compact structure, smaller boundary dimension than other same volume boilers, it can save the investment of capital construction for the boiler room.
