COTES - Design and Engineering Services for the Power Industry

JSC SibCOTES is the largest multi-discipline engineering design company in Siberia. It was established in 1992 to contribute to the efficiency improvement of the power industry in Russia and other countries worldwide by providing environmentally friendly, high-quality design and engineering services.

It has since been recognized as one of the major design firms in Russia, and has acquired a reputation in the Russian market, and international market, for its design and engineering services, primarily for utility-sized power generating projects. SibCOTES brings its workforce of more than 400 professional employees to combine their abilities, experience and talents to forge new technical solutions and practical applications of state-of-the-art technologies in the public and private sectors of the power industry.

SibCOTES has extensive experience in the development of engineering projects for design, construction and refurbishment of power units with capacities up to 800MW. This includes steam turbine units, district heating networks and associated pumping stations, new burner installations, flue gas separators and coal-pulverizing systems at power plants in Russia and overseas.

Completed and ongoing power plant engineering work is underway in more than 20 countries including Bosnia and Herzegovina, Bulgaria, China, Chili, Cuba, India, Kazakhstan, Korea, Macedonia, Mongolia, Montenegro, Morocco, Poland, Romania, Serbia and Turkey.

TECHNOLOGY INNOVATIONS FOR POWER INDUSTRY SITES

A characteristic feature of SibCOTES' work is the innovative component in its approach. For each project it undertakes, the company offers both a custom-tailored approach as well as a proven solution.

SibCOTES' staff has developed and certified a number of technology innovations, which are currently being introduced at power industry sites and at production sites worldwide. Some of these include, a low NOx staged combustion system, a pneumatic flow enhancement system for raw-coal bunkers, adjustable coal-burners, high density pulverized-coal feed system and the circular furnace boiler.

CIRCULAR FURNACE BOILER

The design and development of an innovative and functional coal-fired circular furnace boiler has become the driving symbol of the company. The application of the circular furnace has enabled SibCOTES to achieve the following: reduce the boiler height (by 30%-40%), provide cost-efficient combustion of problem clinkering coals without slagging, reduce NOx emissions, and decrease the installed cost of the boiler.

In 2000, the scientific and technological committee of RAO "UES of Russia" endorsed the design for commercial application. An operating Circular Furnace Boiler, with a steaming capacity of 820t/h was commissioned in 1998 and is successfully operating at Novoirkutskaya CHP in Eastern Siberia (Russia).

OTHER BOILER TECHNOLOGIES

SibCOTES is currently engaged in work on several circulating fluidized bed (CFB) boiler designs at Irkutskaya CHP-5 and Ulan-Udenskaya CHP-2.
