FIELD: hot-gas heat recovery. SUBSTANCE: boiler may be used to produce steam of low and average pressure. Gas-tube heat recovery boiler has body with inlet and outlet chambers for gas, gas-tube bundle mounted in tube plates and provided with evaporating and heating surfaces, pipe connections for feed-water supply and removal of produced steam. Upper part of evaporating surface of gas tubes has vertical lanes in tube bundle between parallel rows of tubes which flow area exceeds that between tubes in heating and lower parts of evaporating surface of tube bundle which are continuously filled with tubes. EFFECT: intensification of heat transfer in water volume and enhanced reliability of operation. 3 cl, 4 dwg
