i) Powerplant
ii) chimney
iii) chimney
iv)ships​

Answer 1

powerplant:-elctric utility generating station

Answer 2

Answer:

i)Powerplant..

Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current.

The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Clean energy sources include nuclear power, and an increasing use of renewables such as solar, wind, wave, geothermal, and hydroelectric.

ii)

chimney is an architectural ventilationstructure made of masonry, clay or metal that isolates hot toxic exhaust gases or smokeproduced by a boiler, stove, furnace, incinerator or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the flue. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships.

A vertical chimney erected on the mechanical penthouse of a residential high rise in Ontario, Canada for ejecting combustion products from the building's water boiler.

In the United States, the term 'Smokestack industry' refers to the environmental impacts of burning fossil fuels by industrial society including the electric industry during its earliest history. The term smokestack(colloquially, stack) is also used when referring to locomotive chimneys or ship chimneys, and the term funnel can also be used.

The height of a chimney influences its ability to transfer flue gases to the external environment via stack effect. Additionally, the dispersion of pollutants at higher altitudes can reduce their impact on the immediate surroundings. The dispersion of pollutants over a greater area can reduce their concentrations and facilitate compliance with regulatory limits.

iii)

Marine engines on ships are responsible for propulsion of the vessel from one port to another. The marine engines are heat enginesused for converting heat, which is generated by burning fuel, into useful work, i.e. developing thermal energy and transforming it into mechanical energy. ...
