Short description:
Main and detailed design I&C project for Cogeneration plant based on biomass combustion with associated equipment and infrastructure. 
Onsite electrical instrumentation of complete I&C equipment, developing and commissioning of control system for complete boiler plant with biomass supply system.
Detailed Description:
In the period from 2014-2015. the company designed and commissioned cogeneration plant based on biomass combustion for a client BE-TO GLINA d.o.o.
In 2015. we finished all electrical and instrumentation works, software design, testing and start-up activities of complete boiler plant.
Boiler plant consist of: steam biomass boiler, biomass day tanks, apparatus for shredding biomass transporters, combustion air fans, a device for purifying flue gases, 
air and flue gas ducts, flue gas exhaust fan, chimney, feed water pumps, thermal water treatment, chemical water treatment, system for the exclusion of ash from the boiler and apparatus for purifying flue gases.
Control system is developed on Siemens PCS7 platform in redundant "fail safe" version. Control system monitors all technological units of complete plant: storage and transportation of biomass, steam boiler, electric filter system, turbine plant, condensing plant, chemical water treatment plant and heating substations for the distribution of process steam for the drying and heating needs.
