DZL series single-drum vertical chain-grate steam boiler is a type of industrial boiler that is capable of burning both coal and biomass fuels. It has a simple and compact structure, consisting of a single drum that is vertically positioned and equipped with a chain-grate combustion device. The boiler is designed to generate steam by heating water through the combustion of fuel in the furnace. The steam produced can be used for a variety of applications, including power generation, heating, and industrial processes.
This type of boiler is known for its high efficiency and low emissions, making it a popular choice in industries that require reliable and sustainable energy solutions. It is also designed to be easy to install and operate, with a high degree of automation and safety features.
Overall, the single-drum vertical chain-grate steam boiler is a versatile and efficient industrial boiler that can meet the energy needs of a wide range of industries.
Working principle:
The single-drum vertical chain grate steam boiler adopts chain grate technology. The fuel is burned on the grate, producing high-temperature flue gas, which is then absorbed by the boiler's heat transfer surfaces and the flue gas is discharged outside the boiler. The steam-water circulation system of the boiler absorbs heat through the heat transfer surfaces, generating steam for industrial production and life use.
Structural characteristics:
-
The overall layout is compact and occupies a small footprint, which is suitable for installation in areas with limited space, and is convenient for construction and maintenance.
-
The boiler drum is arranged vertically, and the layout of water pipes and flue gas pipes is reasonable, which improves the heat transfer efficiency of flue gas and water vapor.
-
The chain grate is used, which has the functions of independently adjusting the air volume of the wind chamber and stepless speed regulation of the grate, making the fuel combustion more uniform and adaptable.
-
Coal or biomass can be used as fuel, which has the advantages of strong flexibility and environmental friendliness.
Advantages
-
The compact structure and small footprint make the boiler room layout simple and require less infrastructure investment.
-
The boiler adopts a quick-installation or assembly structure, which is easy to install, has a high degree of assembly, short installation period, and low installation cost.
-
The chain grate has a separate air volume adjustment for each compartment, and a mechanical ash discharge device, which has good combustion adaptability.
-
The efficient heat transfer method is adopted. The boiler uses a closed water-cooled tube structure and multiple bundles of convective heat transfer surface tubes, which improves the efficiency of both radiation heat transfer and convective heat transfer, and the boiler has high thermal efficiency and small heat loss.
-
The boiler is safe and reliable, with remote and close monitoring, automatic control and monitoring instruments, and easy operation.
-
It has a wide range of adaptability and can adapt to various coal and biomass fuels, suitable for different working conditions.
