In what aspects is the energy saving of gas steam generator reflected? What are some ways to reduce heat loss?
At present, many companies have applied new gas steam generator equipment in the implementation and development process. The emergence and application of this equipment has greatly helped our production and manufacturing. Basically, the relative energy saving of gas steam generator is adopted. What are the main aspects of energy saving in steam generators?
Gas steam generator energy saving
1. During the implementation of the gas steam generator, the fuel and air are completely mixed: a good ratio of combustion with appropriate fuel and appropriate air components can not only improve the combustion efficiency of the fuel, but also reduce the emission of polluting gases. Achieve the purpose of two-way energy saving.
2. The heat of the sewage discharged from the steam generator is recycled again: through heat exchange, the heat in the continuous sewage is used to increase the supply temperature of the deoxygenated water, thereby achieving the energy saving purpose of the gas steam generator.
3. According to the amount of steam required for industrial production, scientifically and rationally select the rated power of the steam generator and the number of steam generators. The higher the match between these two situations and the specific situation, the smaller the smoke exhaust loss and the more obvious the energy saving effect.
4. Reduce the exhaust temperature of the gas steam generator: Reduce the exhaust temperature of the steam generator. The efficiency of ordinary steam generators is 85-88%, and the exhaust gas temperature is 220-230°C. If an economizer is set, with the help of waste heat, the exhaust temperature will drop to 140-150°C, and the efficiency of the steam generator can be increased to 90-93%.
How to reduce or avoid the heat loss of the gas steam generator to achieve energy saving effects and ensure that each internal combustion engine does not lack oxygen combustion?
In what aspects is the energy saving of gas steam generator reflected?
1. Can reduce heat loss: maintain the metal joints of gas steam generators.
2. Can reduce exhaust heat loss: properly control the air coefficient; promptly check whether the flue is leaking; minimize the use of cold air during operation of the operating system; timely clean and decoke, and maintain any heating surface, especially air preheating Clean the heating surface of the device and reduce the exhaust gas temperature. The air supply and air intake should try to use the hot air on the top of the gas steam generator or the hot air on the skin wall of the rear heating surface.
3. Reduce the heat loss of incomplete chemical combustion: mainly to ensure an appropriate excess air coefficient, to ensure that each internal combustion engine does not lack oxygen, and to ensure that fuel and air are fully mixed at high temperatures.
4. It can reduce the heat loss of incomplete combustion of mechanical equipment: the appropriate excess air coefficient should be controlled to ensure that the fineness of pulverized coal is qualified; the volume and height of the combustion chamber are appropriate, the structure and performance are stable, the layout is reasonable, and the primary wind speed and secondary wind speed are appropriately adjusted. Wind speed, appropriately increase the secondary wind speed to increase combustion. The aerodynamic field in the gas steam generator works stably, and the flame can fill the gas steam generator.
