Working project "Furnace room for heating the administrative building"
The working draft "Furnace room for heating of the administrative building at the address: Kyiv region, Brovary ......" was developed by the designers of our company.
Previously, the administrative building was heated by a gas boiler. In order to optimise heating costs, it was decided to switch to solid fuel.
The new solid fuel boiler house, based on a Heiztechnik Hit Pellet Duo boiler with a heat output of 70 kW, was to be installed in place of the gas boiler house. The gas equipment and boilers were dismantled.
Specialists of the IVK ENERGY carried out works on the development of technical solutions for the arrangement of a solid fuel furnace in the existing premises to provide heating of the administrative building.
The main design solutions of this project
- The project envisages the installation of one Heiztechnik Hit Pellet Duo boiler (Poland) with a heat output of 70 kW, fired by solid fuel with automatic loading - pellets. The boiler is equipped with a steel heat exchanger. In boilers, ignition and combustion takes place in the burner.
The fuel is fed to the boiler's flame burner automatically from the boiler's 300 dm3 feed hopper by means of a screw. The design of the boiler provides for the possibility of operating the boiler also in the mode of manual fuel loading
- Placing thermal and mechanical equipment in the furnace (boiler, combs, pumps, membrane tank, hydraulic separator (hydraulic boom).
- Flue gas removal from the boiler is provided by means of natural draft through an individual design chimney with a height of 6.0 m 200nzh/260oz.
- Development of solutions for automation and internal power supply.
- Utilities (water supply, electricity, building heating system) are connected to the respective network inlets inside the furnace building.
- Parameters of the furnace room:
- area of 6.6 m2, ceiling height of 4 m, building volume of 23.1 m3;
- The walls are brick, the floor is concrete, and the ceilings are concrete slabs.
- Fire resistance class of the boiler room walls is I. The fire hazard category is "G". The fire resistance limit is not less than 0.75 hours.
The boiler room is classified as consequence class CC1.
The thermal scheme of the furnace (boiler room) is as follows
The heat loads are to be covered by a heat carrier - water with a design temperature according to the heating schedule of 70/50°C from one hot water boiler:
Heiztechnik Hit Pellet Duo (Poland) with a thermal capacity of 70 kW, operating on solid fuel pellets with automatic loading.
Hot water supply is not provided.
To maintain the water temperature at the inlet to the boilers at least 550C and to prevent condensation on the surface of the boilers, the scheme provides for a three-way bimetallic valve ESBE VTC511 Ду 32.
To separate the boiler circuit and heating system circuits, a hydraulic separator HS-26 is used Termojet.
Water circulation in the boiler circuit is provided by a Termojet Auto APE 25/60-180 boiler pump
The circulation of the heating medium in the 6 circuits of the heating system is forced and is carried out by network pumps individual for each circuit.
Filters are installed on the return pipe before the pumps and check valves after the pumps.
The heating system is closed. To compensate for thermal expansion, a 100-litre expansion tank is installed in the furnace room.
After the boiler, a safety group with a 2 bar relief valve is installed in the supply pipe. The water discharge from the discharge valve is discharged into the existing sewerage system.
A separate line with an electromagnetic valve is provided for automatic heating system supply to the set pressure, which is activated in the event of a pressure drop in the heating system by receiving a signal from an electrocontact pressure gauge.
The detailed design was completed according to the agreed schedule. The documentation was handed over to the customer at the end of October 2023. The customer plans to start installation immediately after receiving the design documentation. The furnace room for heating the administrative building will save money both now and in the future by using cheaper fuel.
