Last year, a thermal gas power plant with 1.6 MW performance was inaugurated in Balatonszabadi. The facility floor was insulated with RAVATHERM XPS. In the closed-circuit power plant, enough electricity is produced for about 2500 households for one year from manure and plant by-products.
The aim of the investment is to exploit manure, raw materials of plant origin and food industry by-products from renewable livestock farms for renewable energy purposes. Ádám Ragoncza, managing director of the contractor Nawaro Kft. said that Hungarian-developed technology is used, which has an advantage over many biogas plants, in that it can also be used for the processing of animal manure. The plant produces 5.2 million m3 biogas per year in a fully closed system, which is used in a small gas power plant to generate electricity and thermal energy. From biogas, the plant is capable of generating nearly 10.3 GWh of green electricity per year, and approximately 9.7 GWh of thermal energy is also generated. The solid and liquid final product produced during the operation is used as bio-manure on agricultural land, eliminating the use of chemical fertilizers. The investment will reduce greenhouse-gas emissions by 10033 tonnes per year.
We are particularly pleased to see our RAVATHERM XPS thermal insulation being used year after year in the investments of buildings that are already energy efficient (we think here of LEED „Gold” certified green office buildings, low-energy stadiums, AA+-certified residential buildings, residential properties), and even in the activity of the small thermal gas plant of Balatonszabadi, it contributes to reducing the negative environmental impacts.
In the case of such a large project, special attention should be paid to the floor’s thermal insulation, because it is exposed to completely different effects than in the case of a residential building. Since the work in the biogas plant still falls into the category of temperature required for normal use, the thermal insulation is not subjected to extreme heat stress, as it would be in the case of a cold storage facility. Although the RAVATHERM XPS is fully suitable to withstand extreme heat, but in our case, mechanical loads are the main issues. In addition to the loads of the building, the weight of equipment and machinery must also be held by the thermal insulation without compression, even for decades. That is why they built the 100 m3 power plant floor with 5 centimeter thick RAVATHERM XPS 300 SL closed cell polystyrene foam thermal insulation with 300 kPa compressive strength. In addition to its high load-bearing capacity, the thermal insulation value of the product is high, which is also preserved in the long term, making it suitable for thermal insulation of the biogas plant in Balatonszabadi and buildings like it.
