Below is information related to the methods and equipment used for construction.
Delivery of machinery, equipment and materials
The success of the entire project begins with carefully planned activities for the delivery of all the required equipment, building materials and other goods.The movement of engineering personnel is usually carried out using light vehicles to carry out activities related to the search and marking of sites, coordinating the project, purchasing goods and services, hiring labor, and staffing.
The subsequent stages require the use of special machines and equipment, such as bulldozers, dump trucks, excavators, motor graders, vibratory rollers and so on.
At this stage, heavy trucks will be needed to transport materials and equipment (concrete, metal, precast tower cranes).
In some cases, trucks weighing about 50 tons, with a maximum width of more than 4 m, a length of more than 15 m and a height of more than 4 m can be used. The use of these vehicles requires the construction of appropriate access roads and even obtaining special permits from local authorities.
Construction site preparation
At the preparatory stage, it may be necessary to dismantle or relocate pre-existing infrastructure facilities that may interfere with the operation of new facilities.The first thing that must be done before the actual start of work is the marking of the territory. It consists in determining the size and location of individual sites. In this case, experts mark the future boundaries of each object.
Preparation of the construction site consists of clearing and leveling the natural landscape, as well as removing the soil layer in accordance with the requirements.
Excavation and foundation works
Despite the relative simplicity of this stage of construction work, simplification or reduction of earthworks is unacceptable.The surface of the construction site must strictly meet the requirements, including elevations, tilt angles, depth and width of trenches, etc.
The soil remaining after excavation is usually used to level out individual sections of the construction site. During the filling trenches and pits, only the material specified in the project is used in a strictly defined amount (sand, gravel).
Steam turbine plants and other massive equipment are usually installed on strong reinforced concrete foundation slabs and pile foundations, the depth of which can reach 20 meters, depending on the characteristics of the soil.
During earthworks, dump excavators, heavy vehicles, bulldozers, rollers, caterpillar tractors, graders, water tankers and small construction equipment will be used. Spot excavations are carried out manually using suitable equipment and tools.
When pouring the foundations, excavators, concrete mixers, cranes, piling machines, auxiliary construction equipment and tools will be used.
Drainage system construction
To ensure adequate rainwater drainage during the construction phase, the design and construction of a temporary drainage system is required. This is especially important when working in a humid climate.The construction of a drainage system involves digging a temporary ditch around the perimeter of the construction site to prevent rainwater from entering the work areas.
Basic construction and installation works
The next stage in the turnkey construction of a thermal power plant is the construction of buildings and the installation of main equipment, including boilers, turbogenerators, pumps for water circulation, chimneys, switchboards, power transformers, communication systems, etc.This equipment can be manufactured in accordance with the design specifications both abroad and in the country of destination. It is delivered to the construction site by appropriate transport and stored in specially equipped places.
Ancillary facilities of thermal power plant
The construction phase involves the construction of facilities for the storage and unloading of coal, offices, warehouses and repair shops, parking lots, a gas station, auxiliary electrical equipment, sanitary and hygiene services, water treatment facilities, as well as a storage area for ash and slag waste.Construction and installation works require the use of various types of cranes, welding machines, hydraulic jacks, pneumatic tools, air compressors, drills, calibration equipment and so on.
Construction waste disposal
The following is information regarding the location of construction waste storage sites and the removal of excess soil after excavation work. The issue of safe waste management is currently of great environmental importance.During construction work at a thermal power plant, construction waste is generated in the form of stones, soil, sand, concrete, scrap metal, wood and other materials.
These wastes are initially stored on the territory of the future coal storage or ash dump, since these zones are built up last and require a minimum amount of work. In the future, they will be buried or taken out for subsequent disposal in strict accordance with the environmental requirements.
Testing and commissioning
Prior to the start of operational tests, temporary structures that were located at the coal storage site will be dismantled.This is necessary to carry out work on the shipment of coal to start the equipment.
Tests include, but are not limited to, the following steps:
• Hydraulic tests of mechanical circuits and water tanks.
• Load tests and insulation checks of electrical equipment.
• Steam turbine test in different operating modes.
• Performance testing of conveyor belt and grinder.
• Check auxiliary and main cooling systems.
• Checking the tightness of the steam lines, etc.
After testing, the process of commissioning the thermal power plant will begin. It consists of chemical cleaning of boilers, blowing pipes, checking safety valves and other works preceding the launch of equipment for full-fledged work.
If the test results are positive, then commercial operation of the TPP by the customer company is allowed. If necessary, the engineering company trains personnel who will operate and maintain the newly installed equipment.
How much does it cost to build a thermal power plant?
Currently, the construction of a combined cycle thermal power plant costs 400.000 to 700.000 euros for each MW of installed capacity.The specific cost is calculated individually and depends on many factors.
The total cost of the project may vary depending on the configuration of the power plant, the equipment used, the features of the construction site, the method of cooling the power plant, etc. The cost of labor in this case does not significantly affect the estimate.
The location of the power plant and the landscape of the construction site play an important role, since the place determines the cost of transporting equipment and building materials, the excavation required, the cost of building power lines, etc.
A significant portion of the funds invested in the thermal power plant project is spent on the construction of structures and cooling systems. The cost of installed equipment has little effect on the total cost, so we recommend that you carefully approach the study of technical characteristics and the selection of the best possible technologies.
Most thermal power plants are currently being designed and built under an EPC contract. The total costs in this case may be slightly higher compared to multi-contract projects, but EPC-contracting provides the business with a single point of contact.
Finally, the cost of building a thermal power plant depends on configuration and capacity. One TPP with one 80 MW power unit will cost less than two power plants with a capacity of 40 MW each or even one TPP with two small power units.
With an average price of 500.000 euros per 1 MW of installed capacity, the total cost of building a 400 MW thermal power plant can reach 200 million euros.
The specific cost will depend on the factors listed, as well as on the country where the construction is planned. It should be noted that as the installed capacity increases, the cost per MW decreases.
