Among many industrial enterprises, boilers are indispensable large-scale thermal power equipment. There are many types of industrial boilers, among which oil-fired boilers, coal-fired boilers and gas-fired boilers are more common. In addition, since industrial boilers are equipment that provides high-temperature and high-pressure hot water, it is necessary to use them in strict accordance with the operating procedures during use to avoid accidents caused by damage to boiler components.
We know that no matter what kind of boiler, during use, the superheater is a heating surface that heats the saturated steam under a certain pressure to the superheated steam under the corresponding pressure. It plays an important role. Important parts missing. However, if the temperature of the superheater pipe exceeds the temperature limit allowed by the material's permanent strength, fatigue strength or surface oxidation, a pipe burst accident is highly likely. Today, Shanghai Hudong Boiler Co., Ltd. has come to give advice on how to prevent the boiler boiler superheater from bursting.
1. When the fuel boiler is warmed up and boosted, it is strictly carried out according to the regulations, and the boosting speed is controlled. According to the regulations, the water discharge in the header of the water wall is carried out, the water circulation is established as soon as possible, and the oil gun is switched in time to ensure that the heated surface is evenly heated, and the half-side combustion is eliminated to eliminate the heat deviation.
2. Strengthen the management of soot blowing and soot blower to prevent serious accumulation of ash on the heated surface. When it is found that the furnace has coking phenomenon, the number of soot blowing should be increased in time to ensure good heat absorption of the water wall; for the heating surface with overheating problem for a long time, install The thermal temperature measurement point is supervised and controlled; the expansion indication device is ensured to be accurate.
3. Do a good job in fuel-fired boiler combustion adjustment to prevent flame deflection, pay attention to control fineness of coal powder, use wind reasonably, prevent coking, reduce heat deviation, prevent re-combustion of fuel oil boiler tail; closely monitor boiler steam parameters, evaporation amount and water level, etc. The main indicators prevent over-temperature, over-pressure, water and water shortages.
4. Ensure the normal quality of the fuel oil boiler and the quality of the steam in operation, reduce the scale and corrosion in the water wall tube, and strengthen the boiler water quality supervision. When the boiler water quality is found to be unqualified, the number of rows should be increased; at the same time, the flow rate of the flue gas, especially the flue gas flow rate at the flue gas corridor, should be controlled. During installation and maintenance, the distance between the superheater tube and the wall should be minimized. At the same time, the distance between the tubes should be as equal as possible.
Oil-fired boiler manufacturer -Shanghai Hudong also pointed out that the explosion of the fuel boiler superheater will not only cause damage to the equipment, but also threaten the personal safety of the user. Therefore, the user is reminded of the strict safety operation requirements when using the oil-fired boiler. To avoid the superheater bursting.
