Scope

GB/T 30839.41-2014 is the English-translated version of 工业电热装置能耗分等第41部分：推送式电阻加热机组.

GB/T 30839.41-2014 is the Chinese standard "Energy consumption grading for industrial electroheat installations - Part 41: Pusher resistance heating unit".

Its scope clause reads: This section GB/T 30839 specifies the various types of push-type resistance heating unit (hereinafter referred to as "push Boiler Unit") energy range, can Consumption parameters, energy consumption and energy classification index measuring method.

This section applies to a natural atmosphere furnace atmosphere and controlled atmosphere, various types of industrial temperature rating in the range of 150 °C ~ 1350 °C With push furnace unit.

Push furnace unit according to the process can be divided into many types of uses, such as. heating unit, quenching unit, annealing line, sintering units, unit carburizing, nitriding Units, soldering machines and other groups.

In addition to the energy unit energy consumption indicators classification and measurement unit also outside the main energy-consuming device push furnace Parameters were grading, as the main parameters of energy status of the unit. Its clauses include terms and definitions; energy range.
