Foreword

This section drafted in accordance with GB/T 1.1-2009 given rules.

The partial replacement of YS/T 119.7-2004 "alumina production thermal balance determination and calculation methods - Part 7 special equipment. Pipe Digestion system. " This portion of YS/T 119.7-2004 main changes are as follows.

--- Increase the computational side of GB/T 11062 natural gas calorific value, density, relative density and Wobbe index of normative reference documents France, GB/T 17820 natural gas;

--- Remove heavy oil project in the determination of measurement methods and salt furnace section, the measured increase of natural gas;

--- Adding new steam and steam condensate was measured in the measurement items and methods;

--- Increases the thermal equilibrium calculations to steam as the heating medium tube digestion system in thermal equilibrium calculations.

The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.
