Chain boiler is a kind of mechanized combustion boiler equipment which is widely used in industrial boilers. It is named for its grate similar to chain crawler. There are many types of boiler parameters, but they must be understood by users when selecting the boiler. ZOZEN Boiler introduces the parameters of 20-ton chain grate boiler.
The 20-ton chain grate boiler drives the chain grate to rotate through the reducer, which makes the solid fuel catch fire from the front and burn out at the tail ...
Before purchasing a set of oil-fired boiler, users should not only care about the quality and price of the boiler, but also consider the thermal efficiency and operating cost of the boiler. Oil-fired boiler is a kind of large-scale industrial equipment, and its energy-saving effect determines the operating cost of a ton of oil-fired boiler, so enterprises should pay attention to it.
Generally speaking, the operating cost of one ton oil-fired boiler mainly includes fuel cost, electricity cost, w...
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...
Boiler heat supply refers to the continuous heat production per unit time when the rated parameters, rated flow, designed fuel and efficiency are guaranteed. There are many ways to express the boiler heat supply, and there are certain conversion standards.
Conversion between heat supply units: 1t/h = 0.7mw = 600,000 kcal/h =720KW
According to the conversion standard, a 5-ton boiler is also a 3.5MW boiler. Therefore, for the users who need 3 million kcal boilers, we recommend WN...
Most petroleum products can be used as fuel, and boiler oil is a kind of refined oil, which is widely used in power plants and industrial boilers. Boiler oil is mainly made of petroleum cracking residue oil and straight-run residue oil, which is characterized by high viscosity and high content of non-hydrocarbon compounds, gum and asphaltene.
The formula of boiler oil mainly includes the following indicators: viscosity of the boiler oil, sulphur content, density, flash point, water content and ...
(1) The furnace drying time depends on the shape, structure and humidity of the furnace. It takes 4 ~ 7 days for small low-pressure boilers and 10 ~ 15 days for heavy furnace walls.
(2) First, bake with wood, on the ash hopper of the room furnace and the grate of the chain furnace, use small fire for natural ventilation within 2 ~ 3 hours. When the temperature of combustion chamber rises, the ventilation capacity will be improved, and the flue damper can be turned down a little. It is best to k...
Before the boiler is put into operation, the furnace wall and arch must be baked and dried, which is called furnace drying. Furnace drying is to slowly dry the damp furnace wall and arch with warm fire to prevent ignition without furnace drying, causing cracking, deformation and serious damage.
Among the commonly used steam boilers, those under the pressure of 3.825 MPa are called medium pressure steam boilers, and those under the pressure from 9.8 MPa to 13 MPa are called high pressure steam boilers. Different boiler pressures have different requirements for water quality. Generally, medium and low pressure steam boilers need to supplement softened water, and softened alkali-free water, while high pressure boilers need desalted water. The different water qualities require different corresponding treatment equipment.
