The burner (not the boiler) is the pressure vessel
The definition of pressure vessels must be the vessel pressure, furnace, is actually the incinerator, do not belong to the scope of the pressure vessel has failed to achieve the most basic conditions, so not pressure vessels.
Friends, combustion furnaces are not under pressure vessel management. Special equipment safety inspection regulations Article 2: Referred to in these regulations refers to the special equipment related to life safety, greater danger of boilers, pressure vessels (including gas cylinders, hereinafter the same), pressure pipes, elevators, lifting machinery, passenger ropeway, large-scale amusement facilities and field (factory) for motor vehicles. Article 99 the meanings of the following terms in these regulations are: (a) boiler, it is to point to use a variety of fuel, electricity or other energy sources, will dress up, in which heated to a certain parameter, and foreign output heat equipment, its range is greater than or equal to 30 l pressure steam boiler; The outlet water pressure is greater than or equal to 0.1 MPa (table pressure), and the pressurized hot water boiler that is rated above or equal to 0.1 MW; Organic heat carrier boiler. (2) of pressure vessel, it is to point to holding gas or liquid, carrying a certain pressure airtight device, its range for maximum working pressure is greater than or equal to 0.1 MPa (table), and the product of the pressure and volume of greater than or equal to 2.5 MPa l. gas, liquefied gas and the highest standard of working temperature is higher than or equal to the boiling point of the mobile and stationary containers of liquid container; All nominal working pressure is greater than or equal to 0.2 MPa pressure (table), and the product of the pressure and volume greater than or equal to 1.0 MPa, L standard of gas, liquefied gas, and the boiling point is equal to or lower than 60 ℃ liquid cylinders; Oxygen tank, etc.
Is, of course. The pressure container is defined as follows: (1) working pressure (note 1) greater than or equal to 0.1 Mpa (work pressure refers to the pressure vessels under normal working condition, the top can reach the highest pressure (pressure)); (no liquid static pressure) (2) the diameter of the inner diameter (for the non-circular section, the width of the width of the diagonal, or the diagonal of the diagonal) is not less than 150mm (3) the working medium is a liquid which is above the standard boiling point for gas, liquefied gas or temperature
