Does the maximum pressure of 0 6Mpa boiler need a boiler certificate?

A stoker operator certificate is required for boilers. Because the boiler is the most dangerous equipment, the operator is required to go through the safety technical training and assessment, and after passing the qualification, and obtain the stoker certificate issued by the safety supervision agency at or above the municipal level or the authorized county-level safety supervision organization, before being allowed to operate the corresponding category of boiler independently. Boiler is one of a kind.

Its saturation temperature under pressure is, that is, under pressure, less than or equal to this temperature, water is liquid, and above this temperature water is gaseous.

Because according to the special regulation TSG 11-2020, the pressure is less than not applicable.

It is necessary to look at the tonnage specifically, basically the gas pressure demand below 3 tons is 8-12kpa, and the gas pressure demand below 3 tons is 12-18kpa.

The gas pressure demand of more than 8 tons is 18-25kpa. The pressure mentioned here is static pressure, which is the pressure of the gas pipeline when the boiler is not opened, and the dynamic pressure is the pressure when the boiler is turned on, which will be lower than the static pressure, about 3-5kpa.

The supply pressure of different types of gas burners is different.

The rated pressure is the highest pressure of the boiler design, and the working pressure is adjusted to be less than the rated pressure according to the needs of the user.

The efficiency of the boiler is highest when the working pressure of the boiler is equal to the rated steam pressure of the boiler.

Rated steam pressure: The outlet steam pressure that should be guaranteed when the steam boiler is running continuously within the specified feed pressure and load range.

The working pressure of the boiler refers to the pressure that the pressure boiler can withstand for long-term operation under the specified working conditions, that is, the safety pressure.

According to national standards.

The boiler design pressure is the calculated pressure specified in the calculation of the strength of the pressure component or pressure element;

The maximum permissible working pressure is the maximum pressure that a compressed component or compressed element can withstand under specified conditions.

The maximum working pressure (rated pressure) is determined according to the minimum value of the maximum pressure that each pressurized part or pressurized element of the boiler can withstand according to the specified conditions.

Summary. Hello dear, happy to answer your <>

The pressure standards for civil boilers are usually determined according to national regulations. Taking China as an example, the pressure standard of civil boilers is generally defined according to the following aspects:1

Boiler design pressure: The design pressure of the boiler should be determined in the design stage. The design pressure is generally formulated by the boiler manufacturer according to user needs, safety requirements and relevant standards, and it is the accurate working pressure of the boiler.

2.Service pressure: The service pressure refers to the working pressure of the boiler in actual operation.

The operating pressure should generally be lower than the design pressure to ensure the safe operation of the boiler. 3.Overpressure Protection:

In order to ensure the safe operation of the boiler under overpressure, civil boilers are usually equipped with overpressure protection devices. In the event that the design pressure is exceeded, the overpressure protection device is automatically activated to control the pressure in the boiler within a safe range. <>

Here are some <> related extensions that we hope you will find helpful

The pressure standards of civil boilers generally follow the following regulations:1National Standards:

According to the Chinese national standard, when the rated evaporation capacity of civil boilers does not exceed 20 tons per hour, the working pressure should be below megapascals (MPa); When the rated evaporation capacity exceeds 20 tons per hour, the working pressure should be below the megapascal (MPa). 2.Industry Standards:

In addition to the national standards, there are also some industry standard axles that are suitable for different types of civil boilers. For example, hot water boilers are mainly designed and evaluated with reference to GB T 1231-2007 "Test Method for Thermal Economic Performance of Boiler Hot Water"; Steam boilers generally meet the requirements of GB 50041-2017 "Building Energy Conservation Design Standards". 3.

Safety standards: In addition to pressure standards, civil boilers also need to comply with relevant safety standards to ensure safety during use. For example, the Regulations on the Safety Management of Boilers and Pressure Vessels specify the safety regulations that boilers must comply with in their use, maintenance, and daily operation.

On the basis of meeting the above standards, according to the actual needs of the user, such as the number of heat supply, the characteristics of the user's living area, etc., personalized design can be carried out to ensure the performance and economy of the boiler. <>

Summary. The maximum allowable working pressure of the boiler refers to the maximum allowable pressure of the boiler during normal operation, which is determined by the boiler manufacturer according to factors such as boiler structure, materials, components, etc. Generally speaking, the maximum allowable working pressure of boilers can be divided into low-pressure boilers and high-pressure boilers.

The maximum allowable working pressure of a low-pressure boiler is generally, while the maximum allowable working pressure of a high-pressure boiler is generally. The determination of the maximum allowable working pressure of the boiler is very important, which can not only ensure the safe operation of the boiler, but also effectively improve the efficiency and service life of the boiler. Therefore, when installing the boiler, the maximum allowable working pressure of the boiler should be determined according to the structure, materials, components and other factors of the boiler to ensure the safe operation of the boiler.

Can you elaborate on that a little bit more?

The maximum allowable working pressure of the boiler is generally high, but the specific pressure value may vary depending on the model and specification of the boiler. If the working and collision pressure of the boiler exceeds the maximum allowable pressure, it may cause damage to the boiler or even occur. Therefore, some measures should be taken to prevent this from happening, such as regularly checking the pressure of the boiler to ensure that it does not exceed the maximum allowable pressure of the shed; Detect abnormal pressure in time and take timely measures to prevent excessive pressure; Regularly inspect the boiler's safety valve to ensure that it can release excessive pressure in a timely manner; Regularly inspect the boiler's exhaust duct to make sure it doesn't clog to prevent the pressure from getting too high.

Personal tip: When using a boiler, you should check the pressure of the boiler regularly to ensure that it does not exceed the maximum allowable pressure to prevent accidents.
