1. In order to prevent condensate from flowing back into the unit, the flat exhaust pipe must have a slope, with the lower end away from the motor and any other part of the pipe where condensate drips, such as the point of vertical inflection of the smoke pipe, drainage outlets must be provided.
2. When the smoke pipe passes through a roof, wall or flammable partition, an insulating sleeve and an exterior panel of the wall must be installed.
3. If conditions permit, arrange most of the smoke pipes outside the engine room as much as possible to reduce radiant heat; all interior smoke pipes must be fitted with thermal insulation sheaths. 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. The smoke pipe terminal should be able to avoid rainwater dripping. The smoke pipe can be extended horizontally and the outlet can be repaired or a rain cap can be installed.
This is related to the power plant settings. Coal consumption here refers to the standard coal consumption rate, which is around 360-450. Actual coal consumption is higher because the calorific value is lower than that of standard coal.
As for water, it is difficult to know the average consumption rate for electricity production. It is linked to the operation of the unit. Additionally, boiler water is consumed. must be replaced regularly. It does not require power plants in rivers and lakes. Condensed water should also be consumed.
The effectiveness ofpower plants is generally less than 40%. This is determined by the second law of thermodynamics. High quality coal will not improve efficiency. The main factors that determine the efficiency of power plants are the main ones. Steam settings and waste steam settings. The main steam parameters are determined by the pressure and temperature resistance conditions of the metal, the maximum is above 600 degrees, 26 MPa. The combustion temperature of coal is much higher than that, so it won't. be limited by the type of coal. Exhaust steam parameters are determined by atmospheric temperature or water temperature and are difficult to change.
Although high-quality coal has a high calorific value and low volatile matter content, it is difficult to ignite and is expensive, so it is generally notused in power plants. Power plants burn relatively lean fuels, including oil shale. and sugar cane slag and the like.
