WNS系列全自動燃氣（燃油）熱風爐

2. Indirect gas fuel hot air stove
It is a high-temperature combustion gas obtained by using a fuel after combustion reaction, through various
A heat exchanger in the form to heat the air. It is mainly suitable for the dry materials not allowed to be contaminated, or applied to the drying of heat-sensitive materials with lower temperature. Such as: milk powder, pharmaceutical, resin, fine chemicals. The fire tube is inserted with a flame-retardant spoiler to slow down the smoke extraction speed and enhance heat exchange. The smoke temperature of the smoke chamber is low, reducing heat loss and saving fuel.

１、直接式高凈化燃氣燃油熱風爐
就是采用燃料直接燃燒,燃料經燃燒反應后得到的高溫燃燒氣體進一步與外界空氣接觸,混合到某一溫度后直接進入干燥室或烘烤房,與被干燥物料相接觸,加熱、蒸發水分,從而獲得燥產品。該種方法燃料的消耗量約比用蒸汽式或其他間接加熱器減少一半左右。因此,在不影響烘干產品品質的情況下,完全可以使用燃氣熱風。

燃料為氣體燃料,如煤氣、天然氣、液體氣。

1. Direct high-purification gas fuel hot air stove
It is the high-temperature combustion obtained by direct combustion of fuel and the combustion reaction of fuel.
The burning gas is further contacted with the outside air, and after being mixed to a certain temperature, directly enters the drying chamber or the baking room, and comes into contact with the material to be dried, heats and evaporates the water, thereby obtaining a dry product. This method consumes about half as much fuel as steam or other indirect heaters. Therefore, the gas hot air can be completely used without affecting the quality of the dried product.

The fuel is a gaseous fuel such as gas, natural gas, or liquid gas.

2、間接式燃氣燃油熱風爐
是采用燃料經燃燒反應后得到的高溫燃燒氣體,通過多種形式的熱交換器來加熱空氣。主要適用于被干燥物料不允許被污染,或應用于溫度較低的熱敏性物料干燥。如:奶粉、制藥、合樹脂、精細化工等。火管內插有阻燃擾流片,減緩排煙速度加強換熱,煙室排出的煙氣溫度低,減少熱損失,節省燃料。

　　隨著政府大力治理環境污染,燃煤鍋爐將逐漸退出市場,而燃油燃氣鍋爐做為90%用戶的首選類型,具有自動化程度高,按照控制器指令自動吹掃,電子自動點火,自動燃燒,風油(氣)自動比例調節,性能安全穩定,燃燒效果好。并有熄火保護裝置,保證安全運行。燃氣中的灰分、含硫量和含氮量比煤低,燃燒充分,煙氣中粉塵量極少,排放易達到國家對燃氣燃油設備所要求的標準,可大大減輕對環境的污染,環保性能好。

　　As the government vigorously manages environmental pollution, coal-fired boilers will gradually withdraw from the market, while fuel-fired gas boilers are the preferred type for 90% of users, with high degree of automation, automatic purging according to controller instructions, electronic auto-ignition, automatic combustion, wind Oil (gas) automatic proportional adjustment, safe and stable performance, good combustion effect. It also has a flameout protection device to ensure safe operation. The ash, sulfur content and nitrogen content in the gas are lower than that of coal, the combustion is sufficient, the amount of dust in the flue gas is very small, and the emission is easy to meet the national standards for gas fuel oil equipment, which can greatly reduce environmental pollution and environmental protection performance. it is good.

　　相對燃煤鍋爐,燃油燃氣鍋爐有如下優勢

　　Compared with coal-fired boilers, fuel gas boilers have the following advantages
1、節省用地:燃油燃氣鍋爐不需要煤灰堆放地,節省用地。

1. Saving land: fuel gas boilers do not need coal ash dumping, saving land
2、減少工作人員:燃油燃氣鍋爐比燃煤鍋爐輔助設備少,所需工作人員少,負擔工資及福利費用就要少得多。

2, reduce the staff: fuel gas boilers less than coal-fired boilers, less staff, less wages and welfare costs.
3、噪聲低:燃油燃氣鍋爐房布置靈活,占地面積少,產生的噪聲低。

3. Low noise: The fuel gas boiler room is flexible in layout, with less floor space and low noise.
