 WNS series horizontal internal combustion full wet back oil-fired boiler , the flue gas process is divided into two forms of two-pass and three-pass. The torch formed after the fuel is burned by the burner is filled in the full-wave furnace and transmits radiant heat through the furnace wall. This is a return journey. The high-temperature flue gas produced by the combustion converges in the back-combustion chamber and turns into the second pass, namely the threaded smoke tube bundle area. After convection heat exchange, the flue gas temperature gradually decreases to the front smoke box, and the second-pass boiler flue gas exits the front smoke box. The boiler body enters the economizer and condenser installed on the top of the furnace, and the flue gas of the three-pass boiler turns from the front smoke box into the three-pass, that is, the light tube bundle area, and then enters the economizer through the rear smoke box, then flows into the chimney, and is discharged into the at...

  Oil gas-fired steam boilers are a kind of boiler products, which are classified according to the type of fuel used in the boiler and the purpose of the product. The fuel gas steam boiler, as its name implies, is a boiler product that can burn gas fuel (natural gas, biogas, liquefied petroleum gas, coal gas, etc.) and light oil or heavy oil. The WNS fuel gas steam boiler refers to the fuel gas steam boiler with a horizontal internal combustion chamber burner, that is to say, the boiler is a horizontal type and the combustion method is an internal combustion chamber burner. WNS oil gas steam boiler is divided into two combustion methods. If burning gas fuel is called gas steam boiler, it is equipped with a gas burner, while burning light oil or heavy oil fuel is called oil-fired steam boiler, which is equipped with oil burner. Advantages of WNS oil gas steam boiler 1. Design Science The WNS oil gas steam boiler adopts a three-pass wet back structure design. The combustion chamber ...

 The operators of gas-fired steam boilers shall be trained and certified to work, and have a deep familiarity with boiler performance and operation related knowledge. Irrelevant personnel are not allowed to enter or leave the boiler room. The ignition precautions for gas-fired steam boilers are as follows. Before ignition of this series of boilers product , a hydraulic test must be done, and the flue and furnace must be ventilated. Before operating the gas boiler, check whether the boiler and its accessories are in good condition and meet the requirements, such as the normal conditions of water pumps, oil pumps, filters and natural gas pressure. Strictly abide by the boiler safety operation system, do a good job in inspections, and frequently check the operating status of the equipment , Make a good record of boiler operation, and report any abnormal conditions to be resolved in time, and the boiler can be operated only after the fault is resolved. Manage the fire-fighting facilit...

 The heavy oil steam boiler is a horizontal internal combustion fuel oil quick-installed boiler with a wet back structure. The corrugated furnace bladder and the re-combustion chamber are one return stroke, the second and third return strokes are threaded smoke pipes, and an energy saver is arranged on the upper part of the boiler. The boiler is equipped with automatic control devices and protection devices with high and low water level alarms and low water level interlocking protection functions; automatic ignition of the boiler, automatic adjustment of the burner power and flameout protection to ensure the operation of the boiler. The designed fuel of this boiler product is light oil or natural gas; the fuel is ejected from the burner, ignited by the electronic ignition rod, and burned in the furnace with a slight positive pressure. The high-temperature flue gas after burning is turned 180° into the back combustion chamber. The three-pass threaded smoke pipe turns 180° from the...

 Among the pollutants of the boiler, the effect of nitrogen oxide emissions on the atmosphere is the most. Therefore, in various boiler pollutant emission standards, the control of this indicator is most stringent. At present, the gas boiler NOx emission limit is most strict, and the region is different, and the requirements are about 30-200. If some boiler is installed, the current nitrogen oxide emissions in the area are more demanding, while the burner burning exhaust emissions cannot meet the latest standards of pollutant emissions in the country, then there is a need for low nitrogen combustion. At present, it is mainly the transformation of gas fired boiler burner. The thermal efficiency of the boiler is a measure of the most important indicator of the boiler. The main factors affecting the efficiency of the boiler are: the heat loss of exhaust, heat dissipation, the fuel is not completely combustion and boiler fouling. Since the burner has not changed the loss of heat dissi...
