This time, DABONN with an automobile manufacturing company in Indonesia. Our technicians customized 3 sets of WNS series gas-fired hot water boilers with a thermal power of 2.1MW ( WNS2.1-1.0/95/70-YQ ).
In the automobile manufacturing process, it is necessary to go through the main processes such as stamping, welding, painting, etc. Some processes have very high requirements for temperature.
For example, the coating process requires high-temperature hot water at 95 ° C or higher. This time, we cooperated with an automobile manufacturing company in Indonesia.
Our technicians customized 3 sets of WNS series gas-fired hot water boilers with a thermal power of 2.1MW (WNS2.1-1.0/95/70-YQ ).
The gas-fired hot water boiler system purchased this time is simple, easy to operate, easy to maintain, and has high thermal efficiency, which saves our company a lot of operating costs.

High efficiency and energy saving is a remarkable feature of this type of boiler. The boiler also has a complete operation control and safety monitoring system, which is very simple and convenient to operate.
And taking into account the actual situation and needs of the company, our company's technical staff tailored the solution to meet their needs, to ensure the reasonable use of the boiler within the maximum range.
The lower part of the electric vacuum hot water boiler is a water chamber. A stainless steel heating tube is installed on the wall of the water chamber. Electric energy is converted into heat energy through the electric heating tube. The upper part is a steam space, in which a row of stainless steel tubes is inserted. Tubular heat exchanger. Since the entire boiler is under negative pressure, it is absolutely safe. The heat medium in the furnace does not enter, exit, increase or decrease during the entire operation of the boiler. It is only enclosed in the vacuum chamber of the boiler and transfers heat between the heat transfer tubes and heat exchangers of the boiler. The heat medium in the furnace is completely deoxygenated pure water, which has no corrosion or scale.

The deep matched technology of new combustion and heat transfer no longer sacrifices the boiler's key characteristics (heat transfer system) to adapt to the burner characteristics (combustion system), making the gas boiler a complete thermal system with low nitrogen emissions. At the same time of obtaining low nitrogen emission, the utilization efficiency of the boiler is further improved.

WNS series gas boilers are energy-saving boilers with shell type, corrugated furnace and threaded smoke tubes. They adopt a three-pass wet-back structure. The fuel is burned in the furnace to produce high-temperature flue gas. It passes through the backfire chamber, the first convection tube bundle, The front smoke box, the second convection tube bundle, the rear smoke box, the normal pressure condenser, and the rear exhaust of the chimney.

The water tank is generally composed of a water inlet pipe, water outlet pipe (domestic water outlet pipe, fire water outlet pipe), overflow pipe, drainage pipe, and other pipes. To measure the quality of the water tank, it depends on how the welding technology is. Welding materials should comply with the current standards "Carbon Structural Steel" and "Carbon Steel Welding Rod"; butt welding is used for splicing steel plates, and other welding is fillet welds. Strengthen the coincidence.

The boiler adopts advanced full premixed combustion technology to achieve super high utilization of fuel, and the operating efficiency is increased by more than 15% compared with ordinary boilers. The integrated structure design reduces the floor space by more than 30%. It is the preferred equipment for energy-saving heating in hotels, shopping malls and schools.

Circulating water pump refers to the circulating liquid pump for conveying reaction, absorption, separation, and absorption liquid regeneration in boiler equipment. Its head is low, and it is only used to overcome the pressure reduction of the circulation system, and a low-lift pump can be used. The flow rate of the circulating water pump is medium, and under stable working conditions, the flow rate of the pump changes relatively little. Its head is small and low, and it is only used to overcome the pressure drop of the circulatory system. Low-lift pumps can be used.

The boiler water is only used as a heat carrier. During operation, the oxygen in the water is heated and precipitated. It is discharged out of the furnace. Oxygen corrosion will not occur in the furnace for long-term use. When the heat medium water is added at one time, a limited amount of calcium and magnesium ions are also heated and softened. The furnace water does not increase or decrease during operation, so no scaling occurs inside the boiler, which prolongs the operation. The service life of the boiler is 1.5 to 2 times that of ordinary boilers.

This furnace type is a condensing boiler with an overall layout based on rigorous thermal theoretical calculations and years of experience in thermal layout pipe networks and using CFD (numerical simulation) technology, which reduces the floor area by more than 40% compared with traditional condensing boilers.
