On the ground, solar energy cannot be used on cloudy days. It also has the disadvantages of high cost and low conversion efficiency. The advantage is environmental protection.
The advantage of hydropower is that it is renewable and environmentally friendly. The downside is that it affects the ecology.
The use of fire energy is more common than the other two, but it is also less efficient and pollutes the environment.
What is the annual duration of electricity production from the thermal power plant? I looked online and it said about 6,000 hours a year. What do you do with the rest of the time? Used for maintenance
I think everyone has some understanding of spark plugs, which are an important part of the engine's ignition system. As for the working principle of the spark plug, it is in fact that the electric plate ofthe spark plug generates electricity and ignites repeatedly and continuously. The high voltage pulsed electricity generated breaks down the air between the two electrodes of the spark plug, thus forming. a spark and an explosion to ignite the gas mixture in the cylinder, then the engine will start. And the spark plug
The working principle of the spark plug
I think everyone has a certain understanding of the spark plug, which is the main component of the engine ignition device. As for the principle of the spark plug, it is actually that the electrical plate of the spark plug is ignited through continuous power generation, and the resulting single-pulse high-voltage line enters into the gas between the two metal electrodes of the spark plug, generates sparks and causes an explosion which ignites the mixture in the cylinder and the engine starts.
CandlesIgnition plugs are consumables and must be replaced regularly. So, the type of spark plug to choose will at the same time affect the operation of the engine. But when we replace the spark plug, many people only pay attention to its material and a few actually, the calorific value of the spark plug is also very important. If you use spark plugs with different calorific values, it is easy to affect the engine power and even directly damage the spark plug. Next, let's talk about how to check the calorific value of the spark plug.
Where to check the calorific value of spark plugs:
The calorific value of spark plugs is expressed in numbers, and this data is usually located in the middle of the model specifications , such as model specifications is BP5E S -1 1, then the number 5 is the calorific value of this boilerignition gy. It is worth mentioning that the calorific value of different brands is different, and the calorific value of each brand has its corresponding car series, so we must be careful in the selection process.
Are spark plugs universal?
In fact, spark plugs are not commonly used. When many people replace spark plugs, they only pay attention to their material and few, but the calorific value. The value of spark plugs is also important. There is a certain attention. The calorific value of each brand corresponds to the corresponding car series. So, when purchasing, be sure to check whether its calorific value matches that of your car series, otherwise it will cause different levels of damage. Let's talk about where the calorific value of the spark plug can be seen.
Où check the calorific value of a spark plug:
The calorific value of a spark plug is expressed in numbers. The calorific value consists of nine numbers from 1 to 9, including. 1-3 are low calorific value, 4-6 is medium calorific value, 7-9 is high calorific value. The calorific value of the spark plugs of most cars is between 5 and 7. This data is usually located in the middle of the model specification. For example, if the model specification is BP5E S -1 1, then the number 5 is the calorific value of this spark plug.
If you choose spark plugs with different calorific values, it will easily affect the engine power, and even the spark plug may be directly damaged. For example, the original calorific value of your car is 7, and during the replacement process, you accidentally replace it with a piston rodn with a calorific value of 4. In this way, there is no effective resistance (high temperature). the car engine keeps running at high speed, the spark plug is easily damaged due to insufficient heat dissipation, so it is very critical to select accurate calorific value. Principle of operation of spark plugs Are spark plugs universal? @2019
First of all, 6,000 hours/year is just an average value. Not all generators run 6,000 hours per year, but some exceed 6,000 hours and others. are less than 6000. Hour.
The reasons are: during the off-peak season, if the power plant units are fully turned on, the power supply will far exceed the electricity consumption, because the electric energy cannot be stored in large quantities. in order to reducecosts, some units will be put into operation. Will stop producing electricity.
During peak power consumption season, power consumption increases significantly, and it may even happen that the power supply is insufficient to meet power consumption. In this case, all units must operate at full load and even supply. electricity to the nearby power grid. (If the power supply is much lower than the power consumption, it will result in insufficient reactive power, which will reduce the voltage level of the power grid and cause large-scale power outages)
So, Most of what you call it other times is because the units stop operating during the off-peak season to cut costs. Of course, a small part of them is due to unit repairs, breakdown shutdowns, unit maintenance and otherare reasons.
