Experience

Since the very beginning of the “Kriger” boiler plant, an important component of its activity has been the export of equipment. For 25 years of history, “Kriger” boilers have been installed in many CIS countries, France, Switzerland, the Czech Republic, Poland, Spain and Great Britain.

Together with our partners from Weiss France a special line of boilers was designed for the market of the European Union. Altogether 52 boilers with a total capacity of 91MW have been manufactured for the French consumers since 2011.

“Kriger” boilers have also earned the trust of Belarusian business, where more than thirty projects have been implemented during this time.

In the period from 2016 till 2019 “Kriger’ LLC delivered 29 hot-water boilers to the UK. The total capacity of boiler plants is 47MW.

The distinctive feature of these projects is the fuel used – wood waste (furniture, chipboard, MDF, etc.), which burning is regulated by the European Waste Incineration Directive (WID).

The morphology of this fuel implies the presence of dangerous pollutants, such as glue, varnish, and as a result – high content of formaldehyde and heavy metals. To solve this problem – a unique combination of adsorption of chemical reagents, flue gases circulation and autonomous control of the combustion process is used. Owing to this, the level of emissions is achieved within the strictest environmental requirements of the British and European legislation without usage of expensive flue gas cleaning systems.

19 of the above-mentioned facilities are cogeneration plants, built in partnership with the high-level O.R.C. turbine manufacturer Electratherm (the USA). Adhering to the individual approach to the implementation of such objects, the engineering group of “Kriger” LLC has developed a modification of the GP series boilers, that are perfectly compatible with the Electratherm turbine model range. 

These objects are parts of business projects with high economic efficiency.

Waste disposal and electricity production is combined with heating of production premises, poultry houses, greenhouses, hot water supply and drying of different types of biomass.

Taking into consideration such a large number of objects, a representative office of “Kriger” company was established in the UK in 2019 – Kriger Boilers UK ltd. This company provides a full business cycle: sales of boilers, projects` support, installation and commissioning kinds of work.

To ensure timely and high-quality warranty and service, a team of Ukrainian engineers is constantly present in the UK, who, in addition to all, train British colleagues to work with “Kriger” equipment.

Bio-thermal power plant in the city of Kamyanets-Podilskiy

The first completely new bio-thermal power plant was built by “Kriger” company in the period 2017-2019 years. This project was implemented under the World Bank program “Ukraine District Heating Energy Efficiency Project”.

Brief description of the object:

• Heat capacity – 39MW;
• Electric power – 1,6MW;
• Fuel -wood chips and biomass of agricultural origin, natural gas (as reserve back-up fuel).

The project concept involves the installation of two “Kriger” solid fuel boilers with a total capacity of 15MW and two standby reserve gas boilers with a total capacity of 12MW each. The electricity generating module is equipped with a modern O.R.C. turbine, manufactured by “Enertime” (France). “Kriger” company implemented this project as a general contractor.

“Kriger” LLC boiler plant manufactured and installed two boilers that use superheated water as a coolant (280C, 24Bar), with a capacity of 5MW and 10MW.

Our company also manufactured a fully automatic fuel storage system: two underground bunkers, a connecting bunker of a “Moving floor” type, a grab crane and a system of scraper conveyors. Such combination ensures autonomous operation of the object during a week.

“Kriger” company also developed a two-level SCADA – system for automated control of a cogeneration plant, which provides for the presence of field control panels for all equipment nodes and a central control and monitoring system. The software allows to fulfill remote control of the plant from any gadget.

The turbine is made on basis of Organic Rankine Cycle.  Such design is optimal for the needs of the city – simultaneous production of electricity, heating of residential buildings and hot water supply. The Enertime turbine has a number of advantages:

• Simplicity of start – up and stopping;
• Possibility of adjustment from 10% till 100%;
• Absence of erosion on the turbine blades, caused by the use of organic liquids in a closed cycle;
• Absence of special requirements for the qualification of the maintenance service personnel and operators.

This project is unique for the markets of Ukraine and Europe and has received recognition at all levels. Its implementation will save up to 10 million cubic meters of gas per year and provide environmentally friendly electricity.
