Definition of Industrial Boiler
A boiler is an energy conversion device. It is also a typical pressure-bearing special equipment. "Electrician Terminology Boiler" (GB/T2900.48-2008) defines a boiler as: using the heat energy released by fuel combustion or other heat energy to heat water or other working fluids to produce specified parameters (temperature, pressure) and quality steam, heat Water or other working medium equipment.
In order to strengthen the safety work of special equipment, prevent special equipment accidents, and ensure personal and property safety, our country has formulated a series of laws and regulations to manage boiler safety. According to the "Special Equipment Safety Law", "Special Equipment Safety Supervision Regulations" and "Special Equipment Catalog", my country defines whether equipment is included in special equipment for supervision.
The "Special Equipment Safety Supervision Regulations" defines boilers as: Boilers refer to equipment that uses various fuels, electricity or other energy sources to heat the liquid contained in it to a certain parameter and output heat energy externally. Pressurized steam boilers greater than or equal to 30L: pressurized hot water boilers with an outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and rated power greater than or equal to 0.1MW; organic heat transfer boilers. Special equipment includes its materials, attached safety accessories, safety protection devices and facilities related to safety protection devices. The state implements catalog management for special equipment. The catalog of special equipment shall be formulated by the department in charge of the safety supervision and management of special equipment under the State Council, and shall be implemented upon approval by the State Council. The categories of boilers in the catalog of special equipment are: pressurized steam boilers; pressurized hot water boilers; organic heat carrier boilers; boiler components; boiler materials. Among them, pressure steam boilers are divided into three types: power plant boilers, industrial boilers, and domestic boilers. Organic heat carrier boilers are divided into two types: organic heat carrier gas phase furnaces and organic heat carrier liquid phase furnaces.
Definition of Industrial Boiler
The concept of industrial boilers was gradually adopted in the late 1930s in order to distinguish them from large-capacity utility boilers. Usually people refer to industrial boilers and domestic boilers together as industrial boilers, and the industrial boilers mentioned in my country's current standard specifications generally also include domestic boilers. "Industrial Steam Boiler Parameter Series" (GB/T1921-2004) clarifies that it is suitable for industrial and domestic fixed steam boilers with water as the medium. Article 11 of the 1999 edition of "Boiler Periodic Inspection Rules" clearly states that industrial boilers are Refers to boilers that provide steam and hot water for industrial production or domestic purposes, and generally refer to boilers with a rated working pressure less than or equal to 2.5MP.
The definition of industrial boiler in "Electrician Terminology Boiler" (GB/T2900.48-2008) is: the steam or hot water produced is mainly used for industrial production and/or civil boilers,
"Boiler Safety Technology Supervision Regulations" (TSG0001-2012) has further adjusted the scope of boilers, and its scope of application includes fixed pressure steam boilers, pressure hot water boilers, organic heat carrier boilers, and surplus (waste) heat The main purpose is flue type and flue and shell combined waste (waste) heat boiler.
The industrial boilers involved in this book correspond to: Yan steam boilers other than power generation (including heat and electricity cogeneration) boilers, flue type and flue and Shell-and-tube combined waste (waste) heat boilers, pressurized hot water boilers, and organic heat carrier boilers.
