CME 542 Exam 1
(T/F): The energy density of coal is higher than that of natural gas because coal is a solid and
natural gas is a gas - ANS-False
(T/F): Selective Catalytic Reduction (SCR) is primarily used for SOx emission control -
ANS-False
(T/F): Changes in electricity demand throughout the day are readily matched using coal as a
generating fuel - ANS-False
(T/F): Most coal-fired power plants operate at 30-40% thermal efficiency because coal is an
inefficient fuel - ANS-False
(T/F): Most coal-fired power plants operate at 30-40% thermal efficiency because coal is an
inefficient fuel - ANS-False
(T/F): The predominant fuel used to generate electricity world-wide currently is natural gas -
ANS-False
(T/F): Approximately 80% of the world's population has access to electricity. This percentage
has remained relatively constant for the past decade and is projected to remain so for the
foreseeable future. - ANS-False
(T/F): The amount of electricity used in the typical US home has decreased significantly over the
past 30+ years because appliances and lighting are so much more efficient today. - ANS-False
(T/F): Achieving higher boiler temperatures in boiler design to increase generation efficiency is
limited by the amount of heat available in the fuel. - ANS-False
(T/F): In pulverized coal combustion, heating water incrementally is less efficient than heating it
in a single stage because incremental heating requires additional pumping which consumes
energy. - ANS-False
(T/F): The specific energy density of hydrogen and natural gas is essentially the same because
both fuels are gases. - ANS-False
(T/F): Nuclear power plants have a higher capacity factor than renewable power plants because
they are so much larger. - ANS-False
(T/F): Hydrogen can be produced from carbonaceous fuels via gasification and the water gas
shift reaction. - ANS-True
, (T/F): Clean coal technologies were developed to minimize the economic and environmental
barriers that limit coal utilization. - ANS-True
(T/F): Cooling towers are used to transfer waste heat to the atmosphere in order to balance the
thermal load. - ANS-True
(T/F): Integrated Gasification Combined Cycle technology is only applicable to natural gas as a
fuel since it combusts gases and coal is a solid fuel. - ANS-False
(T/F): CHP or Cogeneration is particularly well suited to industrial locations where there is
localized demand for heat or process steam. - ANS-True
(T/F): The relationship between a Joule and a calorie is the mechanical equivalent of heat. -
ANS-True
(T/F): Liquified natural gas (LNG) and natural gas liquids (NGL) are two acronyms for the same
thing. - ANS-False
(T/F): Natural gas production generally follows seasonal electricity demand because there is no
way to store it. - ANS-False
(T/F): Renewable generation with solar technologies is well suited for meeting peak electricity
demand because demand typically peaks in the late afternoon when the sunlight is most
intense. - ANS-True
(T/F): The significant increased use of low energy density coal from Wyoming over the past 30
years was a direct result of the need to reduce SOx emissions contributing to acid rain
formation. - ANS-True
(T/F): In the next 25 years, renewable generation technologies are forecasted to be the
dominant electricity generating technology world-wide. - ANS-False
Which of the following statements is true about the relationship between living standards and
electricity consumption?
-There is no relationship between electricity consumption and living standards
-Living standards increase with increased electricity consumption
-Living standards decrease with increased electricity consumption because more income is
spent on electricity instead of food, goods, and services
-Living standards in individual countries will remain the same because world electricity
consumption is forecasted to remain constant - ANS-Living standards increase with increased
electricity consumption
