POSSIBILITY OF BURNING PEAT PELLETS AT COMBINED HEAT AND POWER PLANTS

Expansion of use of local types of fuel and energy resources is presented as one of the priority directions of the energy strategy of Russia for the perspective period. Development of extraction of peat in the Kirov region and a possibility of his use for receiving pellet with the subsequent burning at combined heat and power plant is one of the possible directions of the region's energy development.Расширение использования местных видов топливно- энергетических ресурсов представлено как одно из приоритетных направлений энергетической стратегии России на перспективный период. Развитие добычи торфа в Кировской области и возможность его использования для получения пеллет с последующим сжиганием на ТЭЦ является одним из возможных направлений развития энергетики региона

Measurement of Dispersion Characteristics of Integrated Optical Microresonators and Generation of Coherent Optical Frequency Combs

Optical frequency combs are a unique tool for fundamental metrology, spectroscopy, and a broad spectrum of applications. High-Q microresonators serve as a promising platform for the generation of coherent frequency combs. The key characteristics that determine the properties of an optical frequency comb are the microresonator dispersion parameters. We have developed and verified an original technique that allows one to measure the dispersion coefficients with a high accuracy for both crystalline and integrated microresonators with the free spectral ranges from gigahertz to terahertz. We demonstrate the generation of a soliton optical frequency comb in an integrated microresonator pumped by a laser diode in the self-injection locking regime at a wavelength of 1.55 mu m and show that its spectral characteristics closely correspond to the measured microresonator dispersion parameters
