The Minimum Allowable Values of Energy Efficiency
and Energy Efficiency Grades Industrial Boilers
1 Scope
This standard specifies the energy efficiency grades, minimum allowable values of
energy efficiency, evaluating values of energy conservation and test methods of
industrial boilers.
This standard is applicable to stationary steel steam boilers that the fuel is coal, oil
and gas, the rated steam pressure is larger than 0.04MPa but less than 3.8MPa, the
rated steam output is not less than 0.1 t/h and the medium is water and stationary
steel hot water boilers that the rated water outlet pressure is larger than 0.1MPa.
2 Normative References
The following standards contain the provisions which, through reference in this text,
constitute the provisions of this standard. For dated reference, the subsequent
modification or revisions of these publications do not apply. However, all parties who
reach an agreement according to this standard are encouraged to study whether the
latest edition of these documents is applicable. For undated references, the latest
edition of the normative document is applicable to this standard.

It refers to the minimum thermal efficiency values for evaluating energy conservation
products of industrial boiler under rated condition under test conditions specified in the
standard.
4 Technical Requirements
4.1 Basic Requirements
The technical requirements of industrial boilers applicable to this standard shall meet
the requirements of JB/T 10094 and relevant standards.
4.2 Energy Efficiency Grades of Industrial Boilers
The energy efficiency grades of industrial boilers are divided into 3 grades, and Grade
1 is the highest. The thermal efficiency values of each grade industrial boiler under
rated condition shall not be less than those specified in Table 1 ~ Table 4.
4.3 Minimum Allowable Values of Energy Efficiency of Industrial Boilers
The thermal efficiency values of industrial boilers under rated condition shall not be
less than the specification for Grade 3 in Table 1 ~ Table 4.
4.4 Evaluating Values of Energy Conservation of Industrial Boilers
The thermal efficiency values of industrial boilers under rated condition shall not be
less than the specification for Grade 2 in Table 1 ~ Table 4.
5 Test Methods
The thermal efficiency values of industrial boilers shall be tested according to those
specified in GB/T 10180.
