Biomass steam generator manufacturer It means that if you want to reduce the operating cost of steam, you need to increase Steam generator And reduce the exhaust gas temperature. The reduction of the exhaust gas temperature of the steam generator will reduce the heat loss of the exhaust gas. To reduce the exhaust gas temperature of the steam generator, increase the heating area at the tail of the equipment, and increase the flue gas preheater and preheating tank at the tail of the steam generator. If the exhaust gas temperature at the tail is too low, the flue gas temperature will be reached spot The cost of sulfur dioxide in the flue gas will condense on the surface of the flue gas preheater, which will form low-temperature corrosion.

It can be seen from the on-site test results of the boiler that the boiler thermal efficiency is low when the boiler exhaust gas temperature is high and the excess air coefficient is large, which confirms that the two factors have a great impact on the thermal efficiency. In the case of combustion and flue gas systems, the blower sends air to the air preheater to reach certain temperatures. A part of pulverized coal ground in the coal mill enters the furnace through the burner by a part of hot air in the air preheater. The mixture of pulverized coal and air ejected from the burner is mixed with other hot air in the furnace, thus burning a large amount of heat. After combustion, the hot flue gas flows through the furnace, condensing tube bundle, superheater, energy-saving device and air preheater in turn, and then the fly ash is removed through the dust removal device, and then sent to the chimney to be discharged to the atmosphere by the induced draft fan.

Biomass steam generator manufactor It means that if the fuel with high sulfur content is used for combustion, the low-temperature corrosion will be more serious. The exhaust gas temperature of the steam generator needs to be determined by technical and economic comparison. For the large tonnage steam generator, the exhaust gas temperature is between 110-160 degrees.
