sa 211 gr a1 seamless boiler tube

58 MW circulating fluidized-bed sa 211 gr a1 seamless boiler tube provide by ZG CFB boiler manufacturer, the 58 MW cfb boiler fired with forestry residues, was performed to study the effect on bottom and fly ash. Ash samples from a period of kaolin dosage were compared with ash samples without kaolin.

About tempering gas sa 211 gr a1 seamless boiler tube and fire off phenomenon have what? When the gas boiler during combustion operation, there will be some anomalies, which will directly affect its operational status, such as the device will appear as tempering and fire off such a phenomenon, the negative pressure inside the gas boiler will suddenly become valleys, and the flame color will change ensued, which, we must find the cause and solution to the problem, in order to avoid the risk of accidents.

The party hot water sa 211 gr a1 seamless boiler tube output fast enough to provide high efficiency, give us save a lot of fuel costs, and exhaust gas discharged tested in full compliance with environmental regulations on emissions of air pollutants in Henan Province. Fast boiler responsible attitude also left us with a deep impression, overhaul maintenance problems for a number of aspects of boiler operation and post, sent a very professional technical staff and our butt, fireman guide our people, for the quick sale of party, we are also very satisfied. --customer feedback

Hazard Ultra-low-load operation of the sa 211 gr a1 seamless boiler tube What? Coal-fired boilers is 70% to 100% of rated load, fuel gas boiler 60% to 100% of rated load. Ultra-low-load operation is deemed to run below this range. Then the ultra-low-load operation of the boiler harm What? Fuel gas-fired boiler factory and you came to talk about it! 1. difficult to guarantee the quality of steam: with the boiler load decreases, the steam temperature and humidity will be affected, in particular for a boiler with a superheater, boiler load is reduced, resulting in reduced exit steam temperature is difficult to maintain rated steam temperature, steam quality deterioration. When the superheated steam temperature drops below nominal, soda heating surface system conditions will enter the danger zone, when the load is low zui called technically permissible load. 2. boiler water circulation decreased reliability: fuel gas circulation usually natural circulation. Ultra-low-load operation, because a small amount of fuel into the boiler, the temperature drop across the furnace, the heated water wall weakening, boiler water circulation flow rate will be reduced, reliability is lowered circulation. 3. The rear of the boiler heating surface acid corrosion aggravated: Ultra load operation, the furnace temperature was decreased to varying degrees departments, the exhaust gas temperature will be reduced. It is easy to make the heating surface of the metal wall of cryogenic temperature below the temperature of the vapor *** sulfuric acid, sulfuric acid vapor condensation heating surface will be at a low temperature, resulting in low corrosion of heating surfaces. In summary, fuel gas-fired boiler ultra-low-load operation this issue, we can not be ignored.
