FIELD: water-heating equipment, possibly in water supply systems. ^ SUBSTANCE: boiler includes water-cooled fire tube with rotary chamber and arranged concentrically smoke consuming tubes secured to tube walls and housed in cylindrical shell closed at ends by means of water-cooled covers and covered with insulation jacket. Smoke consuming tubes are inclined relative to axis of fire tube due to turning rear tube wall relative to front tube wall by angle alpha determined according to length of flue pipes. ^ EFFECT: high-intensity heat transmission, compensation of temperature stresses in fire tube pipe and in smoke consuming tubes. ^ 3 cl, 2 dwg |
