FIELD: mechanical engineering. ^ SUBSTANCE: invention heater contains zone of combustion chamber for combustion of fuel and formation of hot combustion products, tubular guide member for combustion products with inlet end zone in which combustion products leaving combustion chamber get into guide member, and with outlet end zone in which at least part of combustion products gets out of guide member for combustion products. Limits heat transfer streamlined space, being made, mainly, of bowl shape with peripheral zone enclosing from outside the guide member for combustion products, and with zone of bottom following outlet end zone in direction of longitudinal axis L of guide member for combustion products. Tubular guide member for combustion products is closed in its outlet end zone in direction of longitudinal axis L by wall of bottom and it has several outlet holes for combustion products getting from guide member into heat transfer streamlined space. ^ EFFECT: provision of improved transfer of heat transported by combustion products to medium to be heated at compact design height. ^ 7 cl, 2 dwg |
