9.2 The Fans and smoke exhausters.
The fans and smoke exhausters are selected by the value of the flow rate of the air
and products of combustion, respectively, accounting for 10-30% of the stock supply
[11].
At the term work are needs present their main characteristics which are: brand, size,
flow, pressure at the output (difference), the working gas temperature, the shaft speed,
the efficiency and the power.

9.3. The Nozzles and burners.
For the combustion of liquid fuel are selects the nozzles by the value of the fluid
flow rate. For feeding fuel oil are used the nozzles with steam or air spray (Gf =
0,017...0.33 kg/s ) and mechanical spray (Gf = ,53...2,78 kg/s) [6, p. 355].
For combustion of the gaseous fuel are used burners without pre-mixing fuel with air
and partial pre-mix (Vg = 0,2...4 m3/s), and pre-mix (Vg = 0,1 m3/s) with air [6, p.
349].

10. THE FINAL DESIGN OF COURSEWORK

Course work must be written by the student on one side of sheets of white A4 papers.
Except the cover sheet and task course work on each page the main frames should be
done at a black color according form 2а ГОСТ 2.104-68. On the page with
“Content”, frame is done with the main label according form 2. ГОСТ 2.104-68.
The first sheet is course work cover sheet, the second sheet is a task for the course work
and the third sheet is the content. The first and second sheets are not numbered. The
inscription on the title page must be performed by a font of type A or B according to
ГОСТ 2.304-81. Font size should be from 3.5 to 10 depending on the content of the
inscriptions (see proposal E).
The cover sheet should be made of white paper, more dense than the sheets of the text
part of the course work.
The sheets of the coursework must be stapled with metal staples.

11. DEFENDING OF THE COURSE WORK

Course work must be verified by a teacher before the defense. Signature of the
teacher is a permition on defending of a course work.
Defending of the course works will be performing by a Commission from 2-3
teachers.
During defending of the course work a student performs a brief presentation (3-5
minutes), which indicates the subject and volume of the work, measured results and
conclusions. After the report the student will be need to answer on the questions.
Evaluation of course work depends to the perfection of the developed questions, the
quality and correctness of calculations, text and graphic parts-no job, systematicity and
autonomy of the work of the student, the clarity of the report and the identification of
knowledge when answering the questions.
