There are two types of waste (hot) water in power plants: one is circulating industrial water (which should not be used for bathing); the other is sewage discharged from boilers (which contains a variety of pollutants and is not suitable for swimming). bathing). If it is condensed water, it will be reused in the boiler (usually recovered in the turbine condenser). Such good water will not be wasted.
It is perfectly possible to use the residual heat steam to heat the bath water. Today's thermal power plants use this model to achieve social benefits.
If the tall, thin chimney of a power plant emits white smoke, is it toxic?
The white smoke emitted by thermal power plants is not polluting. You cannot see the white smoke emitted from chimneys in summer or in good weather, because our power plantsics use ultra-low emissions. means exporting chimneys. The steam temperature has increased;
But in winter or rainy weather, you can still see white smoke coming out of the chimney. In fact, what comes out is not white smoke, but. non-polluting water vapor. Just like the white mist that comes out of our mouths in winter.
Detailed information
The reason why people have a stereotype of "high pollution" of thermal power plants is mainly because the technology of the past was backward and burning coal was not efficient. Due to the lack of smoke treatment equipment, thermal power plants will inevitably emit shocking black smoke.
This black smoke includes incompletely burned carbon black particles, heavy metal compounds, toxic nitrogen oxides, sulfur dioxide, carbon monoxide and others.are gases. In many cases, this black smoke even destroys surrounding trees and homes. is inhaled by humans and animals, it is extremely difficult to be excreted from the body. Even if nearby residents do not have professional environmental knowledge, they will personally feel the damage caused by thermal power plants to their bodies.
Zhoushan New District Grid - Will “white smoke” emitted from power plant chimneys pollute the environment?
I can responsibly say: Yes.
Reason: Our teacher said so.
Deeper reason: Most power plants use thermal energy to produce electricity. The principle is primary battery, that is, the process of burning carbon to generate carbon dioxide generates electricity through the transfer of electrons. But themost of them do not use pure carbon. It contains a lot of impurities, like sulfur, nitrogen, etc. Oxides generated at high temperatures are toxic, so even though they are white, they are also toxic.
Hydroelectric power does not require a chimney.
