Oil Fired Boilers Definitive Guide FAQ
For the WNS series, we have many kinds of boilers for sale, like natural gas boilers, industrial oil fired boilers, diesel fired boiler, propane steam boiler, furnace oil boiler, etc.
Let me show you the whole oil boiler’s working process.
The fuel fires in the burner and flame transfer the radiant heat through the furnace wall, we call this 1st pass.
The reversal chamber collects the high-temperature smoke, these smoke will enter in the 2nd pass, which is the grooved tube bundle area.
The smooth tubes bundle area is named the 3rd pass. The smoke exchanges the heating and then enters into economizer and condenser, finally exhaust emission from the chimney.
In the working process, the three-return design makes full use of flue gas heat, which ensures that your diesel boiler fuel consumption is reduced to a very lower level.
- Oil fired boilers’ drum cylinder: the pressure equipment, to generate the heating.
- Burner: to fire the fuel (oil, gas, LPG, diesel oil, etc.)
- Cylinder: pressure vessel of natural gas boilers, to distribute the steam to valves and pipes.
- Water softener: to soften hard water to ensure gas fired steam boiler normal working.
- Condenser: to improve oil-fired boilers efficiency and save cost.
- Deaerator: to remove oxygen in feed water and ensure natural gas boiler’s water quality.
- Water tank: to supply the feed water for natural gas boilers.
- Pump: including the feedwater pump, circulating pump, deoxygenation pump.
- Control cabinet: to ensure automatic operation. Automatic control system equipped PLC to offer the following controls, including combustion, over-hearing protection, over-pressure protection, water shortage protection.
- Valves and Instruments: to connect the pipe and display operational parameters.
- Chimney: exhaust emission.
Now, you can get the lowest oil boilers price but with the above whole systems.
The most important parts in the above oil boilers reviews are that we designed and equipped with a condenser. The condenser is the most different structure.
After using it, we can decrease the temperature to 60-80℃ and recover part of the heat from emission. So, the condenser is another reason why we could make your diesel boiler fuel consumption the lowest.
Meanwhile, our oil-fired boilers can reduce harmful emissions and environmental pollution during heat recovery processing.
Yongxing oil-fired steam generators also equip with large furnaces, this design improves combustion efficiency and makes the fuel burn more fully. It enables you to provide for lower NOx emissions.
Considering both energy-efficient and environmentally friendly, Yongxing Boilers can be used in food industries, textile mills, petrochemical plants, machinery manufacturing factories, and so on.
