Small vertical Gas steam generator equipment Compared with oil fired and electric heating steam boilers, it can reduce fuel by 30%, Steam generator The heating area can reach 92%. In addition, the heat generated by the supporting economizer can be fully absorbed by the boiler, which greatly saves the operating cost of the boiler. In addition, it also meets the environmental protection regulations in all aspects, so it is widely used in bio pharmaceutical, food processing, brewing, paper making, rubber and other industries.

Gas steam generator The scientific heat collecting combustion structure is adopted to replace the boiler burning structure of the traditional steam cabinet, and the combustion is stable. The heat energy utilization rate of fuel combustion can reach more than 95%. The water tank is made of stainless steel, with fast heat conduction and corrosion resistance. The gas steam generator uses the principle of secondary use of heat energy, and adopts a scientific heat collecting combustion structure to replace the boiler burning structure of the traditional steam cabinet. The combustion is stable, and the heat energy utilization rate of fuel combustion can reach more than 95%. The water tank is made of high quality stainless steel, with fast heat conduction and corrosion resistance.

Water steam corrosion mainly occurs in the parts with poor water flow conditions on the boiler heating surface. In case of water vapor stratification, poor water flow and other parts, water vapor corrosion is characterized by a tight "scale" iron oxide layer on the metal surface, and a large area of thinning of the metal below. Anti corrosion measures The corrosion of the steam water system will cause damage to the main equipment in the steam system, or even scrap. Therefore, take effective measures to prevent corrosion.

small-scale Vertical gas steam generator equipment The boiler water shall be completely deaerated and degassed deaerator To eliminate the factors that aggravate corrosion; When the equipment is out of service, nitrogen or water shall be filled to prevent oxygen corrosion, and the equipment shall be well protected when out of service. In addition, under the condition of high cr content in the boiler water, it is also necessary to consider properly improving the alkalinity of the boiler water. If there are sediments or corrosion products on the metal surface, they should be removed in time to protect the cleanness of the metal surface, and try to avoid long-term static immersion in the equipment with oxygen containing water.
