Project worker for reconstruction of wet gas treatment building for boiler room

2.3

General Instructions

For list of main sets per object, refer to 814.1-3-78.0-00-TM.

This working project is developed on the basis of tasks of adjacent departments for designing heating and ventilation in accordance with SNiP 2.04.05-91 *, SNiP II-35-76 .

Outside air design parameters:

cold period of the year: minus 26 ° С;

warm period of the year: + 23.1 ° С.

The average temperature of the heating period is minus 2.7 ° C.

The source of heat supply is this boiler house.

The coolant for the heating system is water with parameters of 110-70 ° C .

The boiler room heating system is designed two-pipe horizontal. Cast iron radiators MS-140-108 GOST 8690-94 are used as heating devices.

Ventilation of the boiler room with natural motive. Air exchange is determined from the condition of assimilation of heat wastes.

Air ducts of BE1-BE3 systems shall be made of galvanized steel GOST 14918-80 class H with thickness according to SNiP 2.04.05-91 *.

2.4

Install heating and ventilation systems, refer to SNiP 3.05.01-85.

Pipelines at the intersection of partitions and internal walls shall be laid in casings made of non-combustible materials.

Structures of insulated shafts, installation of passage units, opening framugs, mechanisms for opening framugs, etc., see 814.1-3-78.0-00-AP.

For the materials submitted for approval, see 814.1-3-78.0-00-501.
