Briefly discuss the details of the brazing operation after the gas generator produces ash during operation.
During the operation of the gas generator, strict attention should be paid to whether the gas generator and its ancillary equipment, instruments, etc. are in normal condition. If abnormalities are found, they should be inspected and repaired.
After each ash removal, a general or partial furnace blasting must be decided based on the material layer decline and ventilation conditions. When the fire layer is uneven, drill to the part with high fire layer. When the ash layer is uneven, drill to the part with high ash layer. When there is a cavity and hanging phenomenon in combustion, drill to the hanging part to make it tight. When slagging is found in the furnace, it should be drilled. When the furnace is normal, it should be drilled less.
Coal filling method of gas generator: currently,gas generatorThere are two ways to add coal: coal spreading and coal stacking. The coal distribution type stoker is required to continuously and evenly distribute coal over the entire furnace section layer by layer; it also requires strict sealing to ensure that there is no convection between the gas in the furnace and the outside air. For double-bell stoker, the rod pulls the ratchet, and the ratchet rotates the camshaft of the stoker, and swings the upper and lower bell levers, driving the bell valve to open and close alternately. Matched with the movement of the bell jar are coal-moving fins. The action of the gas generator is also completed by connecting rods. The distributor is equipped with a ball plate that can freely swing up, down, left, right, forward and backward. The uniformity of coal distribution is adjusted by hand.
The gas production process of the gas generator is a process of continuous drying, carbonization, and reduction gasification. Coal addition should make the coal seam change as little as possible to ensure the quality of the gas and help to add coal evenly and continuously. When adding coal, it is necessary to add coal at an even time and at intervals as much as possible; and coal should be added less each time, but more frequently, so that the gas generation furnace material layer changes evenly.
