JB/T7090-93
Note: ① The data in brackets are rarely used in China at present and are generally not adopted. ② The gas volume at the inlet of the waste heat boiler refers to m/h at 0.101MPa (760mmHg), 0C. The feed water temperature of the waste heat boiler is 20℃ when the gas volume is not more than 17.9×10m/h, and 105℃ (with economizer) when the gas volume is more than 17.9×10m/h.
The average steam production during the oxygen blowing period is the theoretical calculated value of full vaporization under the condition of gas volume at the inlet of the waste heat boiler and gas temperature drop △t=600C. Since the steam production changes with the change of gas volume and gas temperature drop, the design unit can adjust it according to the specific situation in the design. Additional remarks:
This standard is proposed by the Ministry of Machinery Industry.
This standard is under the jurisdiction of Hangzhou Waste Heat Boiler Research Institute. This standard is drafted by Shanghai Hujiang Machinery Factory. The main drafters of this standard are Bingkui, Li Yufu, Zheng Faqing and Li Yunsen.
