Development purpose
Nitrogen oxide emission abatement during use of power stations steam boilers and high power hot-water boilers that are operated with natural gas.
Make-up of development
- the natural gas two-stage burning technology manufacturing application by burners reconstruction and on line control theirs capability (are applied at 20 power units for capacities 200 and 300 MW);
- installation of special gas burners for two-stage natural gas burning (are applied at high power hot-water boilers PTWM and KVGM);
- manufacturing application of different methods for recirculation combustion products with air and specially developed gas burner constructions (are applied).
Energy efficient and economic data: manufacturing application of developed technologies provides nitrogen oxide emission decrease till 60 %, for high power hot-water boilers it also provides the efficiency increase till 0,5 %. Manufacturing application of mentioned technologies on the whole in Ukraine provides the natural gas economy till 6 millions m³/year (economic benefits will be ~0,5 millions $/year). Pay-back period – 1 year.
