We know that there may be some minor problems in the use of the boiler, then we need to consider the transformation of the boiler to make it work more efficiently.
We know that there may be some minor problems in the use of the boiler, then we need to consider the transformation of the boiler to make it work more efficiently.
According to the principle of no major changes to the boiler body, and the requirements for boiler performance after the transformation, after repeated calculations and careful considerations, the boiler dimensions are determined to be unchanged. In order to adapt to the combustion of blast furnace gas, the internal structure and size are correspondingly changed.膛 volume, the cold ash hopper and the original pulverized coal burner are removed, and the furnace wall is directly built up to 1E. After the modification of this scheme, the hot surface of the furnace wall is ignited from the original 5 such adiabatic chamber to the low calorific value blast furnace gas. Low load and stable combustion is very beneficial. In order to ensure the safety and reliability of the water circulation, the front, rear and side wall water walls are divided into three independent circulation loops, totaling 0 circulation loops. Under the water wall, the headers (front, back, and left and right sides) are separated by a partition. The center height of the boiler drum is 0E, and the downward expansion of the furnace water wall is calculated to be above 51EE, so the sealing between the lower part of the water wall and the insulating furnace chamber is particularly important. In order to ensure the performance of the boiler, non-metallic flexibility is adopted. The expansion device can ensure the expansion of the up, down, left and right directions in multiple directions without changing the sealing property.
After the boiler is modified according to the above method, it needs to be tested to make it more in line with the design principle and work efficiency. Http://?ID=374
