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.
DZL type quick assembly boiler is a single drum longitudinal chain grate boiler. It is suitable for burning molded biomass fuel, and can also burn pure coal and molded biomass fuel. There is an economizer at the rear. The discharged ash and slag can be directly used as farmyard fertilizer, which is an efficient, energy-saving and environmentally friendly product. It is equipped with a drum induced draft fan for mechanical ventilation and a spiral slag discharging machine for mechanical slag discharging. The control and monitoring instruments are complete, making the boiler operation safe and reliable.

The SZS low-nitrogen condensing gas boiler is a double-drum longitudinal "D" type quick-installed water tube boiler. It consists of an upper and lower drum, a membrane water-cooled wall, a convection tube bundle and a flue gas condensation recovery device. After the fuel is burned in the furnace, the flue gas is discharged into the chimney through the convection tube bundle and the flue gas condensation recovery device.

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 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.

The boiler regularly discharges sewage or waste hot water whose pressure is higher than that output by the regular blowdown expander and separates secondary steam and waste hot water through decompression and expansion. The secondary steam can be discharged into the atmosphere or used as a heat source, and the waste hot water is generally discharged into the sewer system through the sewage cooling pool. In this way, the recovery of secondary steam and waste hot water can be used as a heat source, and a part of the heat loss caused by the boiler blowdown can be recovered, and the efficiency of the boiler can be improved.

The SZL series double-drum vertical chain grate water tube steam boiler adopts a quick installation or assembly structure. For 4-6t/h capacity, it is a quick installation water tube structure and is fully assembled in the factory before delivery. For 6-35t/h capacity, it consists of two major components: the upper part is the heating surface, and the lower part is the combustion equipment. The high-temperature flue gas is directed through the convection heating surface and passes through an economizer and dust collector before being discharged.

A sampling cooler is an instrument mainly used for sampling and cooling steam and water in the boiler room or power plant, including a cooling water tank, water inlet pipe, flange cover, water outlet pipe, confluence tank, and several cooling coils and other accessories. It can effectively improve water quality analysis accuracy while connecting points between devices is simple. The sampling cooler is suitable for sampling high-temperature liquids and gases and has the advantages of a compact structure, high heat transfer efficiency, convenient cleaning, and long service life.

In the system of oil-fired and gas-fired boilers, the condensing heat exchanger is the corresponding waste heat recovery and utilization equipment installed at the end of the boiler. If the flue gas is around the heat transfer surface, the corresponding near-wall surface temperature will gradually drop to the dew point temperature, which is accompanied by the cooling and condensation process of the water vapor, thereby releasing the corresponding heat and conducting the heat to the interior through the heat transfer surface. The specific working fluid is used, and then the heat in the exhaust gas is collected again, so as to achieve the purpose of energy saving and environmental protection of the system.
