1. Recommendations for the arrangement of generator exhaust ducts, engine exhaust ducts and diesel generator exhaust ducts:
1. The corrugated pipe is connected to the unit's exhaust outlet to absorb thermal expansion, displacement and vibration.
2. When the silencer is placed in the engine room, it can be supported from the ground depending on its size and weight.
3. In the parts of the generator exhaust pipe, engine exhaust pipe and diesel generator exhaust pipe that change direction, it is recommended to install expansion joints to compensate for the thermal expansion of the pipes when the unit is running.
4. The inside bend radius of the 90 degree elbow must match the pipe diameter.
5. Place the level 1 silencer as close to the unit as possible.
6. When the pipeline is long, iIt is recommended to install a rear silencer at the end.
7. The outlet of the smoke evacuation terminal cannot be directly facing flammable substances or buildings.
8. The unit's smoke exhaust outlet must not withstand high pressure and all steel pipes must be supported and secured using steel buildings or structures.
2. Installation of generator exhaust pipe, engine exhaust pipe and diesel generator exhaust pipe:
1. To prevent condensate from flowing back into the unit, apartment. the exhaust pipe must have a slope, with the lower end away from the engine; in the muffler and other parts of the pipeline where condensation drips, such as generator exhaust pipes, engine exhaust ducts and diesel generator exhaust pipes at vertical turns. should be provided.
2.When generator exhaust pipes, engine exhaust ducts and diesel generator exhaust pipes pass through flammable roofs, walls or partitions, thermal insulation sleeves and exterior panels of walls must be installed.
3. If conditions permit, arrange most of the generator exhaust pipes, engine exhaust pipes and diesel generator exhaust pipes outside the engine room as much as possible to reduce radiant heat inside. insulating sheath. If, due to installation conditions, the silencer and other pipes must be placed inside, the entire pipe must be wrapped and insulated with 50 mm thick high-density insulating material and a plastic jacket. aluminum.
4. Thermal expansion must be allowed when the pipeline support is attached;
5. Generator exhaust pipe terminalserator, engine exhaust pipe and diesel generator exhaust pipe must be able to be installed. to avoid raindrops. The smoke pipe can be extended horizontally and the outlet can be repaired or a rain cap can be installed.
What is the difference between direct air cooling and indirect air cooling in thermal power plants?
Based on the analysis of the pH value of 6 that you proposed:
1. There is a problem with the quality of the medicine. It depends if the sodium acid you added is present. of inferior quality. This is the most likely possibility;
2. Test the pH of your boiler fill water. This could be due to acidic fill water, then there is a problem with your water production system;
3. This is a leak problem. Considering the pH value, focus on checking for any possibleit is leaking acid into the system.
I did both. Both direct air cooling and indirect air cooling are based on circulating water cooling. It uses an air cooling island with a large fan and an air cooling surface. Yes, you can take a look at the Suzhou electric field. Indirect air cooling is done via an intermediate cooling tower (similar in shape to a cooling water tower). There are intercooling triangles around the bottom of the intercooling tower. It is cooled by air convection. inside and outside the intermediate cooling tower. You can take a look at the 660,000 units of the electric field in Qinling, Shaanxi.
