The boiler is composed of membrane wall, tube bundle, steam drum, furnace wall, header and other components, among which the boiler steam drum is a very important pressure component.
Boiler steam drum, also known as drum, is an important pressure component in natural circulation boiler and forced circulation boiler. It is a cylindrical pressure vessel used for steam-water separation and steam purification in water tube boiler, which forms a water circulation loop and stores boiler water...
The boiler economizer is a device installed at the lower part of the flue at the tail of the boiler to recover the waste heat of the exhaust gas. It absorbs the heat of the high-temperature flue gas to heat the boiler feed water, reduces the temperature of the exhaust gas of the boiler, saves energy and improves the thermal efficiency of the boiler. Therefore, when using boilers, it is very important to master the correct treatment method of boiler economizer tube burst.
When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
The principle of boiler economizer is that the flue gas from the boiler tail enters the boiler economizer, and the water in the boiler economizer absorbs the temperature in the flue gas through the finned tube and then returns to the boiler, which is equivalent to raising the boiler feed water temperature and reducing the energy consumption when the boiler output is certain.
Boiler economizer is generally installed at the tail of boiler flue. Due to the different principles and boiler equipment...
1. Water leakage on the inner wall: Water leakage on the inner wall can be divided into three types: boiler leakage, water wall leakage and downcomer leakage. If the leakage holes of boiler barrel and water wall are relatively small, it is ok to use steel with the same steel grade for patching and flaw detection. If the downcomer is leaking, it needs to be replaced.
2. The hand hole leaks: you can re-install it from another angle to see if the hand hole cover is deformed. If it is deformed, you...
Horizontal steam boiler structure
The horizontal internal combustion boiler has a large-diameter shell, in which a furnace is arranged, and the burner is placed in the furnace to form an internal combustion chamber. Both ends of the furnace are respectively connected with the front and rear tube plates, and the smoke tube is arranged between the front and rear tube plates, so there is no need for bricklaying walls outside the boiler. The structure is mainly composed of boiler shell, furnace, f...
Raw water: refers to water that has not been disinfected and filtered, such as river water, stream water, well water, reservoir water, etc.
Feed water: refers to the chemical water delivered from deaerator to boiler by feed pump.
Make-up water: Make-up water for boiler is to make up the lost part or externally supplied part after completing a steam-water cycle, so that the boiler can always operate at a safe water level.
Recycling condensing water: When the heat energy of steam or hot water i...
The boiler drum is connected with downcomer and water wall to form a natural circulation loop. At the same time, the boiler drum receives the feed water from the economizer and delivers saturated steam to the superheater. Therefore, the boiler drum is the connecting hub of the three processes of heating, evaporation and overheating in the boiler.
