The furnace body of the oil-fired steam boiler is designed and adopted a three-pass, wet-back type, and the firebox is an eccentric furnace with an asymmetric structure. The tank of the quick installation oil boiler is designed as a corrugated tank, which can reduce the stress caused by thermal expansion. At the same time, this series of boiler products also increase the rigidity, enhance the flue gas disturbance, improve the thermal efficiency, and increase the radiation heating area.
The heat transfer tubes of oil-fired boilers basically use threaded tubes, which makes the flue gas flow long. A strong convection heating surface is formed, and the heat transfer effect is good. This series of oil-fired boilers are equipped with imported burners (low NOx burners), which burn fully, and the harmful components in the flue gas are lower than the standard (NOx emissions are lower than 400mg/m3), which are environmentally friendly products.
The quick installation oil boiler is rich in control functions, with alarms for insufficient gas pressure and leakage. Digital intelligent control technology applicable to WNS series steam boilers. The combustion process can be monitored remotely. The imported components used have multiple interlocks. The boiler can add a communication interface and print the operating parameters of the boiler, and can design and install a computer control system for multiple boilers.
Quickly install the steam boiler setting indicator light, all parts are clear at a glance. There is automatic leak detection to prevent accidents caused by leakage. A condensing heat exchanger or an air preheater can be added to improve the thermal efficiency of the boiler. After the addition, the boiler efficiency can be increased to more than 95%. At the same time, this structure greatly reduces the heat dissipation loss at the rear of the boiler. In order to improve the thermal efficiency, an economizer and a condenser are arranged in sequence at the outlet of the front smoke box of this type of boiler, which saves energy.
WNS series oil-fired boilers monitor and control water level and pressure effectively. The boiler is equipped with water level gauge and electrode type water level control alarm. It is also equipped with a pressure gauge and a pressure controller, so that the boiler has high and low water level alarm/low water level interlock protection and steam pressure overpressure interlock protection. Automatic ignition of the boiler, automatic adjustment of the fire power of the burner and flameout protection to ensure the safe operation of the boiler.
Through integrated equipment, the quick installation oil boiler covers an area of 18% less than the previous generation. This series of oil-fired boilers have a short preheating period, quick start-up, and short time to enter the working state, saving fuel costs. WNS oil-fired boiler 24h automatic forecast, on-site and mobile phone dual alarm. The boiler adopts imported low NOx electronic proportional adjustment burner. Add FGR system (external recirculation of flue gas). Reduce NOx emission by reducing flame temperature, lean oxygen combustion and reduction reaction (nitrogen oxide emission <30mg/m3, in line with current environmental protection emission standards).
