After testing, the technicians of DABONN customized a WNS series steam boiler system solution (WNS4-1.25-YQ) for the company.
The boiler is an important energy equipment in chemical production, providing a large amount of thermal energy for chemical processes such as polymerization, drying, and dehydration.
The company that cooperates with DABONN is located in Sudan in northern Africa and is mainly engaged in the manufacture and sale of mineral fertilizers and chemical reagents.
As the company's production capacity continues to expand, the original boiler equipment can not meet the company's actual production needs.
After testing, the technicians of DABONN customized a WNS series steam boiler system solution (WNS4-1.25-YQ) for the company.
Considering that Sudan's local oil resources are abundant, under our proposal, the company chose to use diesel with higher calorific value as boiler fuel.
DABONN's modern large-scale professional production line left us with a deep impression. Not only completed delivery within the agreed time but also provided complete after-sales service.

The steam boiler of the WNS series is a horizontal structure, and the economizer and the condenser are located at the top of the boiler, which greatly saves the overall footprint of the boiler and reduces the capital cost of the boiler house.
The boiler furnace has a large volume, and the fuel can be fully expanded and the thermal efficiency exceeds 98%. At the same time, the boiler also has more than 10 monitoring devices to dynamically monitor the operating status of the boiler.
The skid-mounted gas boiler is an integrated boiler system that collects all auxiliary equipment such as the boiler body, control system, water softener, soft water tank, feed water pump, steam tank, fuel tank, instrument valves, etc. into one container to realize the entire boiler equipment mobility. The boiler only needs to be connected to the power supply to operate fully automatically. The instrumentation and control systems of the boiler are all completed in the container.

The gas boiler economizer is mainly composed of the flue heat exchanger, thermal insulation regulating water tank, circulating water pipeline, hot water circulating pump, solenoid valve, electrical control, and monitoring and display system. Without changing the original body of the boiler, a flue gas heat exchanger is installed at the exhaust outlet to reduce the exhaust gas temperature of the boiler to a low enough level, and the superheated water vapor in the flue gas will condense, and through heat exchange, It absorbs the physical sensible heat in the exhaust smoke and the latent heat of vaporization released by the condensation of water vapor.

The low nitrogen steam boiler is a boiler shell type full wet backflow three return fire tube structure, The flame burns under slightly positive pressure in the corrugated furnace with high combustion thermal efficiency. The corrugated furnace can be fully extended according to the temperature, and the heat transfer area can also be increased. The second return journey adopts the threaded pipe structure. which improves the heat absorption intensity of the boiler. effectively reduces the smoke exhaust temperature. saves energy reduces consumption, and is economical to use. The third return journey adopts the big smoke tube technology. which can effectively reduce the smoke resistance of the boiler. improve the combustion efficiency of the burner. and reduce the operating noise of the burner. There is enough steam space in the upper part of the boiler, coupled with the use of advanced and reasonable steam separation devices. the steam quality is quite stable.

As the most important auxiliary equipment in boiler equipment, the quality of the burner will directly affect the operating efficiency of the boiler and the emission of nitrogen oxides. DABONN is an integrated (split) burner designed and manufactured in accordance with relevant international and domestic standards. It adopts a multi-stage combustion method and covers a wide range of furnace types. It can be used in water tube boilers, fire tube boilers, modular boilers, and central return types of boilers such as burning boilers.

Corner tube boilers use boiler coal injection technology. After the fuel is ejected in the hot air, it goes through multiple links such as ignition, combustion, coal ash separation, re-contact and combustion, etc. to generate flue gases that enter the boiler. The flue gases are exchanged with each other through water pipes and superheated pipes. After heat transfer, it turns into water vapor and enters the steam turbine to generate electricity. Because the corner tube boiler fully contacts the hot air and the combustion material, the heat energy is maximized, so it has the advantages of high thermal efficiency, energy saving, and environmental protection.

The deaerator pump needs to be used in conjunction with the deaerator in order to play a good deaeration function in the boiler equipment. Generally speaking, the selection of the deaerator pump should not only combine the flow-head curve, but also simulate the working curve after parallel connection through a certain selection software, and also leave a certain margin. Therefore, in the two When the deaerator pumps are connected in parallel, 5-10% of the space can be reserved according to experience, which requires the boiler engineer to have certain technical experience.
