Test and Calculation Methods of Energy Consumption
for Forestry Enterprises
1 Scope
This Standard specifies the terms and definitions of test and calculation methods of
energy consumption, the types of energy, and the scope of test and calculation, the
general requirements for test and calculation, the test and calculation methods, as well
as the classification and calculation of comprehensive energy consumption for forestry
enterprises.
This Standard is applicable to the test and calculation of energy consumption for
forestry enterprises.
2 Normative References
The following documents are indispensable to the application of this document. In
terms of references with a specified date, only versions with a specified date are
applicable to this document. In terms of references without a specified date, the latest
version (including all the modifications) is applicable to this document.
GB/T 2589 General Principles for Calculation of the Comprehensive Energy
Consumption
GB 17167 General Principle for Equipping and Managing the Measuring Instrument of
Energy in Organization of Energy Using
GB/T 23331 Energy Management Systems - Requirements
3 Terms and Definitions
What is defined in GB/T 2589, and the following terms and definitions are applicable
to this document.
3.1 Forestry Enterprises
Forestry enterprises is a collective term for various industrial enterprises related to the
forestry industry. It includes enterprises in wood production, storage and transportation,
wood and bamboo processing, wood-based panel production, chemical industry of
forest products, forestry machinery and biomass energy preparation, etc.
5.3 All equipment for energy using shall receive the test and calculation of energy
consumption within the same statistical reporting period. For equipment for energy
using with periodic production process characteristics, the test and calculation of
energy consumption shall be performed on the baseline of the same product output.
5.4 In terms of forestry enterprises that produce more than one type of products, the
test and calculation of energy consumption shall be independently conducted for the
main production system, the auxiliary production system and the subsidiary production
system of the various products. The energy consumption of the shared auxiliary
production system and the subsidiary production system shall be apportioned in
accordance with the actual proportion of various products in production.
5.5 In terms of forestry enterprises that simultaneously produce more than one type of
products, the test and calculation shall be conducted in accordance with the actual
energy consumption of each type of products. When it is impossible to respectively
calculate the energy consumption of each type of products, it shall be converted into a
standard product for unified test and calculation or be apportioned in accordance with
the ratio of output to energy consumption.
5.6 The comprehensive energy consumption of products shall not include the various
items of energy consumption not used for production, such as: infrastructure
construction and technological transformation, etc.
5.7 The types of energy included in the test and calculation of energy consumption
shall satisfy the requirements for filling in the national energy statistical report; the
various types of energy shall not be repeatedly counted or undercounted. All
equipment for energy using of the main production system, the auxiliary production
system and the subsidiary production system, and related energy-consuming working
mediums and energy consumption used as raw material energy for a certain type of
products also shall not be repeatedly counted or undercounted.
5.8 The principle of converting various types of energy into standard coal shall comply
with the relevant stipulations of GB/T 2589.
6 Test and Calculation Methods
6.1 Test and Calculation of Energy Consumption of Main Production
System
6.1.1 Test boundaries
For the whole production process, starting from the moment that raw materials enter
the production plant, to the packaging and exit-factory of qualified products, conduct
the test on the energy consumption of all equipment for energy using of the main
production system, the energy used as raw materials and the energy consumption
6.1.4 Test and calculation methods
In accordance with the test items and test contents specified in Table 1 and the
requirements of 6.1.2, conduct the test; obtain the various test results of the statistical
reporting period.
The comprehensive energy consumption of the main production system shall be
calculated in accordance with Formula (1):
Where,
Ea---the comprehensive energy consumption of the main production system;
n---the number of energy types consumed in the main production system;
ea,i---the total physical quantity of the ith type of energy consumed in the main
production system;
pa,i---the conversion coefficient of the ith type of energy; converted in accordance with
the calorific value of energy or the equivalent value of energy source.
6.2 Test and Calculation of Energy Consumption of Auxiliary Production
System
6.2.1 Test boundaries
It includes test of energy consumption of all equipment for energy using of the auxiliary
production system, such as: driving force, power supply, machine maintenance, water
supply, compressed air, heating, refrigeration, instrumentation and raw material sites
in the factory, as well as energy consumption formed by relevant energy-consuming
working mediums.
6.2.2 Test requirements
6.2.2.1 The various equipment for energy using of the auxiliary production system shall
Eb---the comprehensive energy consumption of the auxiliary production system;
m---the number of energy types consumed in the auxiliary production system;
eb,i---the total physical quantity of the ith type of energy consumed in the auxiliary
production system;
pb,i---the conversion coefficient of the ith type of energy; converted in accordance with
the calorific value of energy or the equivalent value of energy source.
6.3 Test and Calculation of Energy Consumption of Subsidiary Production
System
6.3.1 Test boundaries
It includes test of energy consumption of all equipment for energy using of the
subsidiary production system, such as: office, central laboratory, central control room,
finished product inspection room and canteen, as well as energy consumption formed
by relevant energy-consuming working mediums.
6.3.2 Test requirements
6.3.2.1 The various equipment for energy using of the subsidiary production system
shall have stable performance and good operating conditions; satisfy the normal
operation of forestry enterprises’ production activities.
6.3.2.2 The subsidiary production system and the main production system shall
determine mutually consistent energy consumption statistical reporting period.
6.3.3 Test content and test frequency
Within the statistical reporting period, the test content and test frequency of energy
consumption of the subsidiary production system shall comply with the stipulations of
Table 3.
