Spesifikasi
Drum kasusun saka sheet tabung arched lan tabung spirally corrugated, supaya minangka kanggo nyegah sheet tabung saka retak. 
Kalandria minggah ditata ing sangisoring gendhing. Kanthi pengaturan iki, zona banyu sing mati ing ngisor drum diilangi, lan endapan angel diilangi. Akibaté, wilayah suhu dhuwur saka drum entuk cooling sing luwih apik, lan fenomena bulge ing ngisor boiler diilangi kanthi efektif.
Desain optimal saka tabung spirally corrugated nguatake transfer panas, nyepetake suhu kanthi cepet lan nambah tingkat uap ketel. 
Iku desain nyoto lengkungan nang pawon sing mbenakake kondhisi pembakaran, nambah fungsi bledug gagal ing lan nyuda emisi polutan saka ketel.
With good sealing, the wind box is easily to operate and can provide rational wind. Consequently, it reduces the air excess coefficient and increases the boiler thermal efficiency.
