ECONOMIC AND TECHNICAL OPPORTUNITIES SHIFTING TPP BOILERS FOR RESOURCES SAVING TECHNOLOGY OF DISTRIBUTED ADMISSION OF REAGENTS INTO THE FURNACE
In the article are considered the issues of shifting TPP boilers for energy and resources saving technologies of combustion the natural gas and the dust of solid fuel. It is given a comparison of technical and economic indicators of the combustion technology of distributed admission of reagents into the furnace, developed by the authors, with the direct-flow burners and with vortex-flow burners. A high economic efficiency of TPP-boilers exploitation in case of shifting for new technology is noted here. Simultaneous reduction in gas consumption and increase of feeding coal dust into the boilers in the prevailing market conditions of fuel prices provides an additional economic advantage. The actions realized at introduction of technology of fuel burning with dispersed input of reagent streams in fire chambers coal-dust boilers of thermal power plant raise service life of the burners and reduce slagging at simultaneous reduction of concentration of oxides of nitrogen in gases removed in the atmosphere, provide increase of amount of developed steam at the lowered fuel consumption with high economic effect. The technical and economic effect on gas boilers is connected with increase of reliability of torches and decrease in emissions of oxides of nitrogen.
