2.1. Summary of the boiler house being designed.

In this project, the main technical solutions of an automated gas boiler house with a thermal capacity of 758kW have been developed. In terms of reliability of heat and power supply, the boiler house belongs to category II. The boiler room is located on the 1st floor in a room measuring 5050 x 7920 (mm). Height of boiler room 2.4 (m). The boiler room in accordance with SNiP in the category of production for explosive, explosion and fire hazard belongs to category "D," in terms of the fire resistance of the building to category II. Main fuel - gas. Reserve and emergency fuel, in accordance with the design assignment, is not provided. Solutions for laying the external gas pipeline are given in an independent project. Boiler room area 44.2m2, construction volume 106m3.

Window openings are used as easy-to-throw structures.

The project provides that the operation of the boiler room is fully automated and does not require the constant presence of duty personnel, and therefore the section "Organization of workplaces" is not developed by the project.

The project also provides that the installation of the boiler house will be carried out by a specialized installation organization equipped with the necessary rigging equipment, instruments and tools necessary for installation and commissioning. The operation of the boiler house is provided by a specialized organization with a license and repair farm. This organization, based on the data of passports received with the equipment, should draw up schedules for the implementation of the PPR, developed measures to ensure the safety of operation, posted posters and safety signs.

2.2. Purpose of boiler house construction.

The purpose of the boiler house construction is to provide thermal energy (in the form of hot water) to the heating and ventilation systems and WCS of the premises of the industrial site. In accordance with the Specification for the development of the boiler house working design, the total load (heat capacity) of the boiler house is determined in the amount of 758kW (taking into account auxiliary needs and thermal losses).

2.3. Basis for project development.

This project is executed on the basis of the Design Agreement and in accordance with the Technical Assignment for the Execution of the Boiler House Detailed Design (Appendix No. 2). The legal justification for the development of the project is the State Design License.

Technical solutions adopted in the project are not subject to patent cleanliness check (SNiP 110194). There are no deviations from the current standards in the project.

The process of construction and installation work should be supervised by the author, technical and state (inspections of FSPN, UGPS, Ministry of Energy, etc.).

2.4. Climatic data and microclimate of premises.

In accordance with the assignment and norms of SNiP 230199 and II3576 *, the following design parameters have been adopted for the designed system:

• external air temperature - minus of 26 wasps;

• air temperature in the boiler hall - plus 12 wasps;

• number of operating hours of the systems per day - 24 hours/day;

• heating period duration - 220 days;

• temperature condition of heat carriers of heating systems - 9070 wasps;

• temperature condition of heat carriers of ventilation systems - 9070 wasps;

• for relative elevation 0.000 level of clean floor of the designed boiler room is accepted;

In the boiler room, the required parameters are provided in accordance with their purpose and the requirements of SNiP. Solutions for boiler room ventilation are given in section "Heating and ventilation"

2.5. Heat consumers. Heat loads.

Consumers of thermal energy generated by the boiler house in accordance with the Terms of Reference determined:

a) heating system - 273kW;

b) ventilation system - 350kW;

c) WAN system - 100kW;

d) own needs of boiler house and heat loss - 35kW;

The total thermal load of thermal energy consumers (excluding losses in the thermal networks of the facility and the boiler room's auxiliary needs) is 723kW, and taking into account losses in the networks and auxiliary needs of the boiler room (4.5%) 758kW.

The boiler house's own needs (heating) were solved due to heat losses from the surface of boilers and pipelines.
