Boiler Room Installation is a very important and professional issue. Obtaining energy by burning a solid, liquid or gas type fuel and putting this energy into efficient use for different purposes is only possible with the right designs. Correct placement of the boilers, which are the source of energy in the installation design, will bring trouble-free operation in terms of both usage and safety. As it is known, in the Energy Performance Regulation of Buildings, it is obligatory to use “central heating” in buildings whose usage area exceeds 2000 m2. There are criteria that must be considered and followed in the design of the boiler room in buildings, both by the Regulation on Energy Performance in Buildings and outside the scope of the regulation. In central heating systems, systems that will provide system economy by controlling the return water temperature to the boiler and the outside air temperature should be selected.
The purpose of the Regulation on Energy Performance in Buildings is to regulate the procedures and principles regarding the effective and efficient use of energy and energy resources in buildings, the prevention of energy waste and the protection of the environment. This Regulation applies to existing and new buildings;
- a) Calculation methods, standards, methods and minimum performance criteria for the preparation and implementation of building projects and energy identity certificate on issues related to the energy use of the building such as architectural design, mechanical installation, lighting, electrical installation,
- b) Authorizations for the issuance of energy identity certificates, building controls and inspection activities,
- c) Meeting the energy need from the cogeneration system and renewable energy sources,
- d) Training and awareness-raising activities for the creation and updating of the building inventory throughout the country, the development of energy culture and efficiency awareness in the society,
- e) It covers the works and procedures regarding the measures and practices to increase energy efficiency in buildings registered as cultural property to be protected, taking the opinion of the Cultural and Natural Heritage Preservation Board and in line with this opinion, implementation of energy efficiency-increasing practices in a way that will not affect the property and external appearance of the building.
However, buildings where production activities are carried out in industrial areas, buildings with a planned usage period of less than two years, greenhouses, workshops and buildings such as warehouses, arsenals, warehouses, barns, barns, which are built individually and do not need to be heated or cooled, are outside the scope of this Regulation.
Boiler Room Installation
Boiler efficiency in buildings with central heating system is higher than 75% in solid fuel boilers, in liquid and gas fueled boilers, the efficiency of New Liquid and Gas Fuel Hot Water Boilers published in the Official Gazette dated 5/6/2008 and numbered 26897 by the Ministry of Industry and Trade. It is determined according to the Regulation on the Requirements. This regulation states that it cannot be lower than 2 star efficiency class. The layout of central heating systems is made according to the TS 2192 standard, and the layout of the systems using gaseous fuel is made according to the TS 3818 standard. The method of heating these environments by transporting the hot fluid prepared in a heat plant to the desired environment is called “central heating”.
Boiler rooms in appropriate sizes should be designed according to the selected boiler type, installation elements and other auxiliary equipment. The minimum volume for the boiler room should be 8 m3. Although it is known that industrial boiler rooms will require dimensions far above these dimensions, it has been mentioned here because it is a written rule. The smallest possible volume should be used, while leaving sufficient space for the placement and maintenance of boilers and other large appliances. The maximum boiler room volume is 21 m3 for every 293 kW (252000 kcal/h) part of the boiler power. At the architectural project stage, an area of suitable size should be allocated according to the following elements. In buildings, the basement is usually chosen as the location of the boiler room. However, with the production of high efficiency and smaller sized boilers in recent years, liquid and gas fueled boilers can also be installed on the roofs of buildings.
During the installation phase of the boiler room, it is located in a central place and as a whole, separated from the other parts of the building by partitions that are resistant to fire for at least 120 minutes. Building dilatation cannot pass through the boiler room. Boiler rooms with a thermal capacity between 50 kW and 350 kW have at least one door, and boiler rooms with a floor area of over 100 m2 or with a thermal capacity of over 350 kW have at least 2 exit doors. Exit doors should be placed in opposite directions of each other as much as possible, they should be fire resistant for at least 90 minutes, smoke-proof and self-closing. Natural gas and LPG installation, project, material selection and installation of the boiler room are made in accordance with the relevant standards and technical specifications of gas companies.
In basements, the boiler room is generally located in the middle of the building, allowing both the chimney to be located in a suitable place and the horizontal distribution pipes to make short and balanced distribution. At the same time, it may be easier to enter the fuel and, if solid fuel is to be used, to store it and to throw the ash out. Together with these features, it allows efficient installation design in the form of bottom distribution and bottom collection. In case the boiler rooms are installed on the roof, it seems advantageous to install the chimney on the roof and lower the hazard class, especially for natural gas boilers, but it becomes difficult to transfer the heated fluid from the top to the bottom. Top distribution and top collection systems are the most inconvenient system in heating installation. In order to operate efficiently, circulation pumps should be placed in the boiler room and at the bottom.
However, it is recommended to have a threshold of at least 10 cm high on the doors opening from the boiler room into the building. In addition, if it is possible to illuminate the boiler room naturally, care should be taken that the lighting openings do not coincide with the other windows of the building. If artificial lighting is used, a system that does not dazzle but illuminates the flat should be installed. Moreover, the main switch and panels of the boiler room should be placed around the entrance door and should be of a sealed type. Fire extinguishers should be available in boiler rooms.
In the Boiler Room Installation process, heating boilers are placed in the closest distance to the chimneys in the placement of the heating center. Fuel tanks are placed in a protected volume with fireproof partitions. The fuel tank and the boiler room must be separated by a fire-resistant partition for 120 minutes. Water tanks, hydrophore and boiler should be placed in close proximity as a separate group. Heat generators should be placed on bases made of firebrick with a thickness of at least 200 mm and properly laid on a reinforced concrete floor. In solid fuel boilers with a grate depth exceeding 1500 millimeters, the pedestal height must be at least 400 mm for perfect combustion and removal of ash and slag. Concrete pedestal height should also be made so that the bottom of the burner is at least 30 cm above the ground when the burner boiler is installed so that the burner fan does not absorb dust from the ground.
In particular, a waste water pit with a volume of at least 0.250 m³ should be built in a suitable part of the boiler room to collect the flowing or leaking water. Fuel-oil streams should never be poured into the waste water pit and the waste water collection pipes. In addition, the net height of the boiler room (floor and under beam) should be at least 2.10 m in cast section boilers. If the distribution collectors are on the boiler, the net height of the boiler room must be at least + 1.90 m. If the distribution collectors are installed along the wall, the boiler room net height is at least + 0.96 m.
should be. In solid fuel boilers with a heating capacity of 100 kW and above, the efficiency is investigated and an automatic fuel supply system is used. If the heating capacity is 100 kW or more, cascade boiler systems can be used, which are reported to be more economical as a result of the initial investment and operating costs and energy economy analyzes, working in communication with each other mechanically and electronically, according to the need.
