FIELD: power industry. ^ SUBSTANCE: method consists in obtaining combustion products themselves by means of fuel combustion in the furnace with further heat extraction from combustion products by means of their warming-up of furnace heating elements with elongation of channels for removal of combustion products to stack. The main flow of combustion products is divided at least into two additional intermediate flows by installing on the way of the main flow of shaped wall with openings, mainly in its peripheral zone. Obtained additional intermediate flows are supplied through the above openings to furnace walls; after that, mainly each additional intermediate flow is turned and passed along the furnace walls in its part located in close proximity to the stack. Additional intermediate flows, mainly all of them, are turned at least once towards each other and swirling movement is given to each flow, mainly along spiral; then, additional intermediate swirling flows are mixed between each other and the obtained main swirling flow is supplied to stack. ^ EFFECT: improving fuel combustion completeness, heating capacity and increasing service life at constant fuel consumption. ^ 4 cl, 4 dwg |
