Some standard content:
1 Subject content and scope of application Machinery Industry Standard of the People's Republic of China Waste heat boiler parameter series Oxygen converter waste heat boiler This standard specifies the basic parameters of oxygen converter waste heat boilers. This standard is applicable to various types of oxygen converter waste heat boilers. Technical content The basic parameters of oxygen converter waste heat boilers are generally specified in the following table. Table Waste heat steel furnace inlet Gas volume X10°m/h Waste heat boiler inlet Gas temperature Approved by the Ministry of Machinery Industry on 1993-10-08 Rated steam pressure Rated steam temperature JB/T7090- Average steam production during oxygen blowing period Implemented on 1994-01-01 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. wwW.bzxz.Net This standard is under the jurisdiction of Hangzhou Waste Heat Boiler Research Institute.
