Preface
Oil fired boiler refers to boiler equipment that uses diesel as fuel. It has a certain low position in the market because of its high combustion efficiency and fully automatic operation. Some users are not very clear about the working principle of diesel steam boilers, here CN Boiler will answer for you.
The boiler is divided into two parts, the pot and the furnace. The pot is a metal container used to hold water, and the furnace is the part where the fuel is incinerated. The water in the pot absorbs the heat of fuel incineration in the furnace and turns into steam. It is equivalent to a kettle, and the stove is equivalent to a stove. Here, CN Boiler will introduce the working principle of oil boiler and oil boilers model.
Working Principle of Oil Fired Steam Boiler
The working principle of the diesel steam boiler: the diesel pump sucks the diesel oil out of the fuel tank, sends it to the ignition plug in the combustion chamber to ignite the mixed gas, and the exhaust gas from the diesel combustion in the combustion chamber is discharged from the waste port. In order to make the fuel burn more fully, the diesel boiler must improve the atomization quality of the oil, the fine surface of the oil particles is uniform, the atomization angle is appropriate, the oil mist is evenly distributed along the circumference, and can be fully mixed with the air.
The burner releases heat by burning diesel oil, which is then absorbed by the water-cooled wall through radiative heat transfer. The water in the water-cooled wall is boiled and vaporized, and a large amount of steam is generated and enters the steam drum for steam-water separation (except for once-through furnaces). If it is a superheated steam boiler, the separated saturated steam enters the superheater, and continues to absorb the heat of the flue gas at the top of the furnace, the horizontal flue, and the tail flue through radiation and convection, and makes the superheated steam reach the required working temperature.
Oil Fired Steam Boiler System
★ Combustion system: furnace, burner, ignition device, storage oil tank, etc.
★ Steam water system: water treatment device, feed water pump, steam header, deaerator, etc.;
The steam water system consists of a feed water part and a steam part.
Feed water part: feed water refers to the water that is provided to the boiler for steam conversion. The feed water channels water into the boiler and automatically controls it to satisfy steam requirements.
★ Control system: intelligent control the oil steam boiler to run or stop
The boiler control system is a collection of boiler electrical control components, a center for collecting and processing boiler operating signals, and an operation platform for sending execution instructions to each execution unit of the boiler.
The Core Control Mode of the oil steam boiler system: HMI+PLC (All-in-one PLC, not programmable), PLC control(programmable), PLC+PC control, DCS control.
★ Air and smoke system: refers to the system composed of flue oil and air generated by combustion, mainly including induced draft fans, chimneys and other equipment;
Although the working principle of the oil steam boiler is basically the same, the configuration of the oil steam boiler system is different according to the user's needs and actual working conditions, Our aim is to achieve green and efficient heat energy conversion.
Oil Fired Boiler Steam Type Brief Introduction
WNS Series Oil Fired Steam Boiler
Rated steam capacity: 1-20t/h, Pressure: 0.7-2.0MPa
The boiler adopts a large-diameter corrugated furnace, which effectively increases the heat transfer area of the furnace, and has the characteristics of fully automatic operation, which is reliable and stable for long-term operation. In addition, the self-developed high-efficiency heat transfer element threaded smoke tube effectively improves thermal efficiency. The boiler structure is simple and occupies a small space.
SZS Series Oil Fired Steam Boiler
Rated steam capacity: 2-110t/h, superheated steam capacity: 8-90 t/h, Pressure: 1.25-5.3MPa
The SZS series oil boiler has a D-shaped layout structure, with the furnace on the right and the convection tube bundle on the left. The boiler adopts a full-membrane water-cooled wall structure, which has good sealing performance and large radiation heating area. Reasonable size of the upper steam drum and configuration of the steam-water separator can reduce entrainment water in steam and improve steam quality. Because it belongs to the water tube boiler, the boiler has a strong pressure bearing capacity and a larger parameter range.
The working principle of the above oil steam boiler hopes to be helpful to everyone. If you need to buy a oil boiler, welcome to consult the manual customer service online or call us directly: 086-0371-56520102, CN Boiler will serve you wholeheartedly.
