GB 50919-2013Code for design of energy conservation of non-ferrous metals smelter (English PDF)

Foreword

This code was prepared jointly by China Nerin Engineering Co., Ltd. and China Nonferrous Engineering Co., Ltd. together with the organizations concerned, in accordance with the requirements of the Notice on Printing and Distributing the "Formulation and Revision Plan of Engineering Construction Standards and Codes for 2005 (Second Batch)" (Jian Biao Han [2005] No. 124) issued by the former Ministry of Construction.

During the preparation of this code, the drafting group carried out in-depth investigation and research, conscientiously summarized the practical experience and technical progress of the non-ferrous smelting industry in recent years, held repeated discussions and widely solicited the opinions of the design, research and production organizations concerned, and finally finalized the code upon review.

This code consists of 8 chapters. The main contents include: general provisions, terms, heavy non-ferrous metals smelting, light non-ferrous metals smelting, rare metals smelting, non-ferrous metallurgical furnaces and kilns, electric power, utilities, etc.

The provisions printed in bold type in this code are mandatory provisions and shall be strictly implemented.

The Ministry of Housing and Urban-Rural Development is in charge of the administration of this code and the interpretation of the mandatory provisions, the China Non-ferrous Metals Industry Engineering Construction Standards Administration Office is responsible for its routine administration, and China Nerin Engineering Co., Ltd. is responsible for the interpretation of specific technical contents. All organizations are kindly requested to sum up experience and accumulate data during the implementation of this code, and to send their comments and suggestions to China Nerin Engineering Co., Ltd. at any time for reference in future revisions.

1 General provisions

1.0.1 This code is formulated with a view to implementing the relevant national laws and regulations in the energy conservation of non-ferrous metals smelters, strengthening energy conservation management, promoting the progress of energy conservation technology and using energy rationally.

1.0.2 This code is applicable to the energy conservation design of new construction, reconstruction and extension projects of non-ferrous metals smelters.

1.0.3 An energy conservation part (chapter) shall be prepared in the feasibility study report and in the preliminary design documents.

1.0.4 New construction, reconstruction or extension projects must adopt new energy-saving processes, new technologies and equipment; the adoption of processes with high energy consumption and of electromechanical products that the State has announced as eliminated is strictly prohibited.

1.0.5 The energy consumption of new construction projects or large reconstruction and extension projects shall reach the grade 1 energy consumption indicators of this code; the energy consumption of medium and small reconstruction and extension projects shall reach the grade 2 energy consumption indicators of this code, and shall not be lower than the grade 3 energy consumption indicators of this code.

1.0.6 When calculating the comprehensive energy consumption, the kilogram of coal equivalent (kgce) shall be used as the unit of energy measurement.

1.0.7 The energy used by waste heat utilization devices shall be included in the energy consumption. The recovered energy, after conversion into standard coal, shall be deducted in the process step or process in which the waste heat is recovered.

1.0.8 In the design of a non-ferrous metals smelter, metering and control instruments shall be provided for the primary energy, secondary energy and energy-consuming working media entering and leaving the plant and entering and leaving the energy-consuming process steps.

1.0.9 The energy conservation design of non-ferrous metals smelters shall comply not only with this code but also with the provisions of the current relevant national standards.
