Winter heating work is related to the lives and work of many people, and it is very important to ensure the normal operation of heating szl chain grate boiler in koreas. As a CBM employee, I am very pleased that our products can help school heating. CBM 's products have been running on the campus of Zhengzhou University many years ago, and have been in good condition so far, which proves once again that CBM's wns series boilers have long service life and reliable operation.
Common circulating hot water szl chain grate boiler in korea fault which appears to have some hot water boiler with natural circulation, the loop structure if it is poorly designed or run properly, it is prone to problems of circulation failure, such as stagnation of circulation, circulation back , soft drinks and other different hierarchical fault, seriously affect the normal operation of the boiler. A cycle arrest causes: in the same cycle, since the riser uneven heating conditions in parallel, where the heated weak strong soda mixture density greater than the density if heated mixture of soda, resulting in the less intensely heated downcomer reduce the flow rate of the inner tube, even result in stagnant phenomenon. Solution: When using the hot water boiler must be able to ensure that each of the tubes are heated uniformly, but also to ensure uniform distribution of water to the downcomer waterwall tubes, thereby ensuring smooth circulation. Second, the loop back causes: the riser parallel uneven heating, and the mixture was heated soda strong upward force is strong, the flow rate is too large, thus generating suction, the heated mixture of soda weak flow in the reverse direction; the bubbles ascending speed equal to the speed of water flowing down, the bubble will cause stagnation, severe gas plug pipe will end where the squib due to high temperature occurred. Solution: The same hot water boiler in use, to ensure that each tube is heated uniformly, but also to ensure uniform distribution of water to the downcomer waterwall tubes, thereby ensuring smooth circulation. Third, soda causes delamination: waterwall tubes disposed horizontally when the inner tube soda mixture flow rate is not high, the upper flow of steam, the water in the lower flow tube, poor thermal conductivity of the steam in the pipe, if the temperature is too high will be the upper duct burn, this phenomenon is called soda stratification. Solution: When the waterwall tubes are arranged to be inclined, the inclination angle of no less than 15 degrees. Hot water boiler During normal operation, the drop is not allowed in the steam tube phenomenon, otherwise the inner tube and water vapor collided, resulting in increased resistance to flow, reducing circulation flow, the water cycle is stopped, resulting in water wall tubes burn out for lack of water.
