LY/T 1529-2012Comprehensive energy consumption of plywood production (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces LY/T 1529-2012 "Comprehensive Energy Consumption for Plywood Production". Compared with LY/T 1529-2012, the main technical changes as follows.

a) Part of the scope has been revised (see Chapter 1, Chapter 1 of the 2012 edition);

b) Deleted the definition of basic energy consumption per unit output of plywood production (see 3.3, 2012 edition of 3.3);

c) Added the definition of comparable comprehensive energy consumption per unit output of plywood production (see 3.3);

d) Modified the grading index for the comparable comprehensive energy consumption per unit output of plywood.

Comparable comprehensive energy consumption per unit output, comparable comprehensive energy consumption per unit output of the entire process (see Chapter 4, Chapter 4 of the 2012 edition);

e) Revised the reference standards of test instruments (see 6.1.1, 6.1.1 of the 2012 edition);

f) Added thickness correction factor (see 5.4.4);

g) Modified the output correction factor (see 5.4.1, 5.4.1 of the 2012 edition);

h) The reference document LY/T 2394 Management Regulations for Energy Measuring Instruments for Forestry Enterprises has been added (see Chapter 2);

i) Modified the excellent, good, and qualified categories in the comparable comprehensive energy consumption grading index for the unit output of plywood and revised it to the first, second, and third level (See Chapter 4, Chapter 4 of the 2012 edition);

j) Modified the calculation formula of comparable comprehensive energy consumption for plywood production (see 5.3).

This document was proposed by the Forestry Energy Management Sub-Technical Committee of the National Energy Foundation and Management Standardization Technical Committee (SAC/TC20/SC7) and focus on it.

1 Scope

This document defines the terms and definitions of the comprehensive energy consumption for the production of ordinary plywood, and specifies the comparable comprehensive energy consumption per unit output of ordinary plywood.

Grading indicators, calculation methods and principles of energy consumption, energy consumption testing and measurement requirements.

This document is applicable to the calculation and index assessment of the production energy consumption of ordinary plywood enterprises using hardwood and conifer logs as raw materials.

3 Terms and definitions

The following terms and definitions defined in GB/T 9846 apply to this document.

Comprehensive energy consumption of plywood production the actual amount of energy consumed by ordinary plywood production enterprises during the statistical reporting period shall be converted into the specified calculation method and unit respectively.

The calculated sum.

"Comprehensive energy consumption of unit output plywood" product" Statistics report the ratio of the comprehensive energy consumption of ordinary plywood production to the output of qualified ordinary plywood during the same period.

Ordinary plywood production unit output comparable comprehensive energy consumption basic energy consumption of unit output plywood product in the ordinary plywood production process, the annual production of plywood is 60000m3<= M <80000m3, and the monthly average temperature is 20°C<=T<35°C when the thickness is 12 mm<H<=15 mm, the amount of energy consumed to produce 1m3 qualified ordinary plywood used under dry conditions.

Direct production system Operations directly related to ordinary plywood production activities, including material preparation, veneer peeling, veneer drying, veneer finishing, glue hot pressing, refer to Appendix A for the general name of sawing and sanding, finished product storage and other processes.

Indirect production system Production activities that provide supporting services for direct production, including auxiliary production systems and auxiliary production systems.

Auxiliary production system Provide three waste treatment, production equipment maintenance, compressed air supply, heating (or cooling) and lighting of the production workshop for direct production.

Subsidiary production system Provide heating (or cooling) and lighting for warehouses, production-related public places, etc. for direct and indirect production.
