I. Reading Exercises:

Exercise 1. Read and memorize using a dictionary:

District heating, cogeneration, footprints, instantaneous, grid demand, thermal stores, sewage, waste heat, excess, renewable,stockage, round trip efficiency,whilst, borehole cluster, pit storage, borehole cluster, district heating network, fjord, outfall, sewage treatment, outfall, boost up, raw sewage, scrubbing working fluid, deploy, chill,energy carrier, breakdown, waste heat  

Exercise 2. Answer the questions:

 

1) How is the heat often obtained?

2) What can district heating plants provide?

3) What do heat sources in use for various district heating systems include?

4) What is waste heat from nuclear power plants sometimes used for?

 

Exercise 3. Match the left part with the right: 1b,2a,3d,4c.

1. Use of solar heat for district heating has been increasing a) for district heating networks.
2. Industrial heat pumps are credible heat sources b) in Denmark and Germany in recent years.  
3. Recent technical advances allow the use of natural heat pump refrigerants c) is very energy efficient.  
4. The combination of cogeneration and district heating d) that have very low global warming potential (GWP).  

 

Exercise 4. Open brackets choosing the write words:

Use of solar(heat/warmth)for district heating has been (increasing/growing) in Denmark and Germany in recent years. The systems usually (include/involve) interseasonal thermal energy storage for a (consistent/compatible) heat output day to day and between summer and winter.

II. Speaking Exercises:

Exercise 1. Learn the definitions: District heating; geothermal heating system; solar heating; waste heat recovery.

 

District heating is a system for distributing heat generated in a centralized location for residential and commercial heating requirements such as space heating and water heating.  

 

A heating system that harnesses the heat energy produced by the earth underground is an example of a geothermal heating system.  

 

solar heating (Miscellaneous Technologies / Building) heat radiation from the sun collected by heat-absorbing panels through which water is circulated: used for domestic hot water, central heating, and heating swimming pools

 

waste heat recovery The use of heat that is produced in a thermodynamic cycle, as in a furnace, combustion engine, etc, in another process, such as heating feedwater or air

 

 

Exercise 2. Ask questions to the given answers:

1) Question: ______________________________________________?

Answer: District heating is a system for distributing heat generated in a centralized location for residential and commercial heating requirements such as space heating and water heating.

2) Question: ______________________________________________?

Answer:Waste heat from nuclear power plants is sometimes used for district heating.

3) Question: ______________________________________________?

Answer: Industrial heat pumps are credible heat sources for district heating networks.

 

 

III. Writing exercises:

Exercise 1. Complete the sentences with the suggested words: of; systems; with; in;

 

The core element 1 many district heating 2 is as a heat-only boiler station. Additionally a cogeneration plant (also called combined heat and power, CHP) is often added in parallel 3 the boilers. Both have 4 common that they are typically based on combustion of primary energy carriers.

 

Exercise 2. Compose a story on one of the topics (up to 100 words):

District heating

Heat sources in use for various district heating systems

Renewable electrical energy
