Annotation: Efficiency increase of heat energy generation by means of water heating boilers use with direct contact of flue gas and circulating heated water on mass and heat exchange bearer is grounded. The stay time of fuel burning products lessening in high temperature zone 0,3 sec and burning products by water dispersion cooling provides NOx emission reduction and heat exchange improvement. Condensation of steams of water on heat-exchange attachment of the probed condensation caldron increases the coefficient of heat emission from the products of combustion of fuel more than in 15 times. Analytical dependence degree of lowering NOx generation on the time the products of combustion in high temperature zone and excess air are defined. The investigation of water-heating condensation boilers shows that NOx and carbon oxide emission less then international indices.
Keywords: condensing water-heating boilers, packing, burning furnase, pollution emission, carbon oxide, NOx.
