IBR CFB Steam Boiler

ZG manufactured IBR CFB steam boiler can be distinguished into new type water cooling whirlpool inner separation low speed circulating fluidized bed boiler and energy saving circulating fluidized bed boiler. IBR CFB steam boilers’ capacity is among 15 to 280 ton/h. IBR CFB steam boiler can also be divided into coal fired CFB steam boiler and biomass fired CFB steam boiler. CFB steam boiler can be widely used into paper industry, textile industry, oil refineries, power plants, chemical industry, glass plants, and so on. Besides, 75 ton coal fired CFB steam boiler is the hot sales product in our ZG Boiler.

The partnership, fast boiler for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback

The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.

How to provide boiler thermal efficiency thermal efficiency of the horizontal 3 pass coal fired steam boilers has the following methods: low-pressure boiler at the factory has been designed considering the problem of thermal efficiency of the boiler, the flue gas from the device or change little aspects of energy-saving possibilities, it is best to start from the energy-saving operation (here talk recovered water vapor condensation method). The current design thermal efficiency of domestic low-pressure boiler is generally 70 to 90%, generally the actual operation of the thermal efficiency of about 60 to 80%, some even below 50%, a small low pressure industry as long as the operation, maintenance properly, can meet the design thermal efficiency of manufacturers. I think the management and operation should pay attention to the following points: First, the boiler flue gas temperature monitoring. Typically the maximum exhaust heat loss is loss, it is important to good control of exhaust gas temperature, exhaust gas temperature is generally low pressure coal-fired boiler of 150 ~ 180 ℃, fuel boiler exhaust gas temperature is 210 ~ 240 ℃, so when the boiler to find out why when the exhaust temperature is too high and promptly eliminated. Coal-fired boiler flue gas temperature is too high reasons are: high furnace pressure; shorting smoke; thick soot on the heat pipe; thick scale pot like. High temperature fuel exhaust reasons are: 1 air not adjusted oil, the oil is not completely burned in the chimney the secondary combustion occurs aft; 2 soot too, the need for timely cleaning; 3 shorting smoke; 4.... thick scale; Second, controlling blowdown rate. Without restricting the general rate of industrial sewage control in 5 to 10%, in the pot of water to ensure that qualified (mainly total alkalinity and pH value), the blowdown rate as low as possible, the sewage to adhere to the "ground row, row less, are ranked "the rules. Third, the maintenance of good furnace wall insulation. The heat loss is also a relatively large heat losses, now the manufacturers in the manufacturing and design has been well thought out, so we do not need to change, we just trying to be difficult to maintain. Outer surface temperature generally does not exceed 50 ℃, it will have to find out the reasons such as too high, and remove. Boiler insulation should always be kept dry, for coal, not a long positive run, or easy to damage the coal furnace wall and gate and so on. Fourth, adjust the ratio of fuel and air volume, complete combustion of the fuel as possible. Generally do not have a small amount of wind testing instruments, we can only go by experience adjustment. For oil, the normal combustion flame was yellow-white, non-glare, flame stability, no visible smoke chimney; For coal, the normal combustion flame pale, no visible smoke chimney, basic cinder burn coal particles as even as possible. Fifth, the need for a sound water treatment. Improve water treatment and water quality testing can maximize prevent fouling and correct guidance of the sewage, but it did not do a lot of small, companies usually do not pay attention.
