The diagrams show the components of a wood pellet stove and wood pellet boiler and how they are used to heat a house. When a wood pellet stove is used, first the wood pellets are fed into the fuel hopper. Then the pellets move through the fuel feed and into the combustion chamber, where they are burned. As they burn, the ashes drop into the ash pan below. The hot air from the burning rises to the combustion fan. It is blown out into the room by the fan. Smoke from the fire exits through the exhaust duct.
When a wood pellet boiler is used, the pellets are also fed into a hopper. From there, they move into the furnace, where they are burned. The ashes go into the ash receptacle and the smoke goes up the smoke stack. Cold water moves into the furnace, where it is heated by the burning pellets. The heated water moves into radiators, which heat each room of the house.
The major difference between the two systems is that the stove heats with hot air and the boiler heats with water.
I agree that everybody, no matter what his or her level of academic ability, should be admitted to university programs. In the first place, everyone has the right to an education and no once can take this away. Also, people are generally attracted to educational programs that fit their interest and abilities. Finally, there are different university programs designed to fit different kinds of students.
Everybody has the right to an education, and this includes education beyond high school. Some people choose to go to a university while others choose some other form of training. No matter what form of education a person chooses, no one else has the right to make that choice for him or her.
People tend to choose educational programs that fir their interests and abilities. They do not need someone else to tell them what they can and cannot do. If a person is interested in studying Law, for example, it is probably because he or she fells it is something he or she likes and will do well at. Also, when students are interested in their program of study, they are motivated to work hard, even when some of the assignments are difficult for them.
There are all different kinds of university programs. There are programs that suit different interests, goals, and abilities. Because of this, there is no reason to deny a university education to anyone. There is something for everyone who wants it at the university level.
Everyone has the right to an education, including a university education if that is what he or she chooses. It should not be denied to anyone.
