Laboratory for Industrial Energy and Environmental Protection (LIEZO)

Head of the laboratory: Doc. dr. sc. Viktor Dragičević, dipl.ing.str.

The Laboratory for Industrial Energy and Environmental Protection was established in 2000 and operates within the Department of Thermodynamics and Energy at the Technical Faculty of Rijeka.

By purchasing appropriate measuring equipment, the conditions for the work of the laboratory on tests for the needs of scientific research as well as outside the framework of the parent institution have been acquired. The Laboratory for Industrial Energy and Environmental Protection has equipment for measuring the efficiency of energy devices and for determining emissions through flue gases from energy and industrial plants.

These measurements are a legal obligation of all owners of power plants and there is a possibility of working with the economy and the market, in order to carry out these measurements as well as control measurements for the needs of the customer.
It will be possible to perform measurements to determine the emissions of harmful substances from pollution sources that can be further used as input data for modeling the operation of the device in real operating conditions or dispersion of pollutants in the atmosphere, and various statistical indicators.

The laboratory conducts warranty tests of the equipment in order to check the efficiency and emission of flue gases declared by the manufacturers. In collaboration with equipment manufacturers, it is possible to conduct research to improve the efficiency of the device and reduce emissions of harmful substances into the air.

Laboratory equipment

No.	Name	Puropuse – scope
1	Device for isokinetic sampling of solids content in gases – SICK SCH-501	determination of solids concentration in waste gas
2	Analytic weighing scale – OHAUS	Precise weight measurment
3	Flue gas analyser TESTO 350-XL	Flue gas analysis
4	Desicator	Sample drying
5	Drying furnace

This equipment is used for research purposes as part of scientific research projects. The measurement results will be used to validate numerical simulations of pollutant transport and simulations of power plant operation.

Equipment for measuring the concentration of solid particles in flue gases is used as part of the research of steam generator efficiency and is used for measurements for the needs of external users.

In addition, the purpose of the equipment is to measure the concentration of solid particles for the needs of other scientific research and technological development projects and for the validation of the results of numerical simulations.

The Laboratory for Industrial Energy and Environmental Protection, which operates within the Department of Thermodynamics and Energy, is able to offer various technical services according to user needs.

With scientific and professional staff and available equipment for measurements and testing, the Laboratory for Industrial Energy and Environmental Protection can offer its customers a wide range of services:

• preventive measurements of emissions as part of the maintenance of thermal power plants
• preparation of studies and studies related to reducing emissions and increasing energy efficiency
• testing the energy efficiency of thermal power plants
• conducting testing of emissions from stationary sources as part of the legal obligations of users

The laboratory is responsible for conducting tests in accordance with the requirements of the international standard HRN EN ISO / IEC 17025: 2005, or parts of the standard relating to the professional and technical competence of the laboratory, and in accordance with the needs of users and the requirements of laws and regulations.
