Taking into account losses (K=1.1) total heat requirement will make
QTOTAL=0.3770 gcal/hх1.1 = 0.41gcal/h.
Proceeding from the above-stated heat loads, there is accepted for installation the
modular transportable automated boiler house KBТА – 0.5 GН with two hot-water boilers
by capacity 0.25 MW each. Total installed capacity of the boiler house will make
0.43gcal/h.
Hot water with parameters T=95-70°C serves as heat carrier for heating and
ventilation systems.
There is accepted tank V=5m3 for water reserve. There is provided raw water
softening in water preparation installations on constant magnets UVPM-1.
As fuel for boilers is accepted natural gas of low pressure. Gas supplied from fuel gas
reduction assembly of Surgil CGTU. Gas hourly consumption for boiler house
ВН=56m3/h. Annual consumption is equal ВН=234534m 3 .
As source of heat supply of camp buildings and constructions serve individual gas
heating water-heating modules of “VITOPEND-100” type, provided with the built-in
circulating pumps and heating gas devices of АОGV type. The heat-carrier - water with
parameters Т=95-70°С.
Heating systems of CGTU buildings and constructions are accepted horizontal flow
with passing movement of the heat carrier. There are accepted cast-iron radiators of МС-
140-108 type and registers from smooth pipes as heaters.
Heating systems of camp office building and dining room are double-piped deadended
with overhead distribution of supply mains. Heating system of hostel is single-pipe
