Foreword
In order to promote the construction of environmental information, establish and improve the environmental information standard system to provide environmental information processing and exchange
Technical support, ensuring the orderly processing and exchange of combustion type information, and unifying the classification and code of combustion methods.
Set this standard.
This standard specifies the classification and code of the combustion method.
This standard is the first release.
This standard was formulated by the Science and Technology Standards Department of the Ministry of Environmental Protection.
This standard was drafted. Information Center of the Ministry of Environmental Protection, Beijing University of Science and Technology.
This standard was approved by the Ministry of Environmental Protection on December 21,.2009.
This standard has been implemented since March 1,.2010.
This standard is explained by the Ministry of Environmental Protection.
Combustion mode code
1 Scope of application
This standard specifies the classification and code of the combustion method.
This standard is applicable to the collection, exchange, processing and use of information on combustion methods at all levels of environmental protection departments across the country.
Management of the construction of environmental management information systems.
2 Normative references
The contents of this standard refer to the terms in the following documents. For undated references, the valid version applies to this
standard.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
Classification of combustion methods
The process of distinguishing and classifying information attributes or characteristics classified according to the combustion method according to certain rules.
The combustion method establishes a certain classification system and the order of arrangement.
3.2
A collection of things that have a common attribute, also known as a category.
3.3
Classification system
The whole of the interrelated categories formed after classification.
3.4
Combustion mode code
A character or set of characters representing the burning mode category.
3.5
Combustion mode coding
Based on the classification of combustion methods, the process of assigning codes to the combustion mode category.
3.6
Code table
The form of expression after classification of combustion methods. The code table in this standard mainly includes the code of the combustion mode category.
Names and notes, etc.
4 Classification principles
4.1 Scientific principles
According to the most stable information attribute of the combustion method and the logical association existing in it, as the basis of classification, and considering the burning side
Characteristics and development requirements.
4.2 Practical Principles
When classifying combustion methods, the category setting should be comprehensive and practical. The important and important combustion methods should be regarded as the first category.
Listed.
4.3 Stability Principle
When classifying combustion methods, we should combine the results of years of combustion technology work in China and consider the points that some departments are using.
Class and coding.
4.4 Extensibility Principle
Reserve space on the expansion of the combustion method category to ensure that the classification system has certain flexibility and can be performed on this classification system.
Extension and refinement
