1 Scope
Method for compiling industrial boiler product models
This standard specifies the method for compiling industrial boiler product models. JB/T1626-2002
This standard applies to fixed steel steam boilers with water as the medium and a rated working pressure greater than 0.04MPa but less than 3.8MPa, and a rated evaporation capacity of not less than 0.1t/h. Steam boilers and fixed steel hot water boilers with rated outlet water pressure greater than 0.1MPa. 2 Model composition
2.1 Industrial boiler product model composition
The product model of industrial boilers (except electric heating boilers) consists of three parts, and each part is connected by a short horizontal line (see Figure 1). The contents of each part are as follows:
a) The first part of the model indicates the boiler body type and combustion equipment type or combustion method and boiler capacity, which is divided into three sections. The first section uses two capital Chinese pinyin letters to represent the boiler body type (see Table 1): The second section uses a capital Chinese pinyin letter to represent the combustion equipment type or combustion method (see Table 2): The third section uses Arabic numerals to indicate the rated evaporation capacity of the steam boiler in t/h or the rated thermal power of the hot water boiler in dry MW. Each section is written continuously. b) The second part of the model indicates the medium parameters. Steam boilers are divided into two sections, connected by a slash in the middle. The first section uses Arabic numerals to indicate the rated steam pressure in MPa; the second section uses Arabic numerals to indicate the superheated steam temperature in C. When the steam temperature is the saturated temperature, the second part of the model has no slash and second section. Hot water boilers are divided into three sections, also connected by a slash in the middle. The first section uses Arabic numerals to indicate the rated outlet water pressure in MPa; the second section and the third section use Arabic numerals to indicate the rated outlet water temperature and the rated inlet water temperature in ℃, respectively. c) The third part of the model indicates the type of fuel. Capital Chinese pinyin letters are used to represent the fuel crystals, and Roman numerals are used to represent different types of the same fuel variety and are listed in parallel (see Table 3). If several fuels are used at the same time, the main fuel is placed in front, separated by the rating number in the middle.
When the boiler body type, combustion equipment type or combustion method, and fuel type exceed the provisions of Table 1, Table 2 and Table 3, the enterprise can refer to the above provisions to compile the product model by itself.

2.2 Electric heating boiler product model composition
JB/T1626—2002
Electric heating boiler product model consists of two parts, each part is connected by a short horizontal line (see Figure 2). The contents of each part are as follows:
a) The first part of the model indicates the boiler body type and the electric heating boiler code and boiler capacity. It is divided into three sections. The first section uses a capital Chinese Pinyin letter to indicate the boiler body type. The boiler body type is divided into horizontal and vertical types. W represents horizontal type and L represents vertical type. The second section uses the Chinese Pinyin letter DR to indicate the code of the electric heating boiler. The third section uses Arabic numerals to indicate the rated evaporation capacity of the steam boiler as a certain t/h or the rated thermal power of the hot water boiler as a certain MW. Each section is written continuously. b) The second part of the model indicates the medium parameters of the boiler. The steam boiler uses Arabic numerals to indicate the rated steam pressure as a certain MPa. The hot water boiler is divided into three sections, and each section is connected by a slash. The first section uses Arabic numerals to indicate the rated outlet water pressure as a certain MPa. The second and third sections use Arabic numerals to indicate the outlet water temperature and inlet water temperature as a certain C, respectively. A
