The CFB mainstream fluidized bed resistance characteristic test should be carried out in accordance with the following steps and requirements: First, ensure that all the air hoods of the air distribution plate are completely cleaned, and there are no blockages, leakages and abnormal installation errors. If there is time, all three types of dampers are fully open, and the working condition test is carried out. Check that there is no bed material on the air distribution board, start the induced draft fan, the primary fan, and sequentially adjust the opening of the primary fan baffle to 5%, 10%, ..., 100%, but limit the primary fan current to not exceed 1.05 times the rated current . Record the pressure in the water-cooled air chamber and the bed pressure in the lower part of the dense phase zone in the furnace. The difference between the two is the resistance of the air distribution plate. It is not recommended to reduce the negative pressure in the furnace to make the bed pressure around zero. Then draw the relationship curve of quasi-cold primary air volume, fan current and baffle opening and resistance according to these data. Through temperature correction, the characteristic relationship curve of hot primary air volume and air distribution board resistance can be obtained.
There are many industrial boiler companies in my country with different design levels. Most of them lack R&D and innovation capabilities. Companies generally have insufficient R&D investment and lack of R&D innovation methods. Less than 10% of companies have R&D capabilities. As the pioneer of domestic industrial boilers, Xinli Boiler has a professional R&D team and 20 years of dedicated research and technology. The boiler products produced cover oil and gas boilers, coal-fired boilers, biomass boilers and heat-conducting oil boilers. The products have excellent performance and high safety guarantee, and have won the favor of all walks of life. What if the boiler barometer is too high.
What if the boiler pressure gauge is high? When the industrial boiler is cold, the water in the evaporation system below the water level of the drum is still. When the riser tube is heated in the boiler, part of the water generates steam, forming a steam-water mixture with a lower density. The downcomer is not heated outside the furnace, and the water density in the tube is relatively high, so that the driving force is generated under the action of the density difference between the two, and the steam-water mixture flows upwards in the water-cooled wall, and enters the steam drum through the upper header and the duct. The water from the steam drum in the downcomer flows downwards and is replenished into the water wall through the lower header. In this way, the continuous circulating flow forms a natural circulation.
With the changes in my country’s energy supply structure policy and increasingly stringent environmental protection requirements, my country’s boilers will develop in the direction of high energy conservation, high efficiency and sufficient combustion in the future. Therefore, promote the transformation of coal-fired and gas-fired boilers to effectively achieve energy conservation and environmental protection. Goals are the key tasks of our country. Xinli Boiler has made great achievements in energy-saving boilers, and its energy-saving technology has developed rapidly, laying a solid foundation for the future.
