FIELD: power engineering.
SUBSTANCE: condensation boiler of external placement comprises a hydraulically insulated body with internal main and additional heat exchangers, a blow burner, direct and reverse lines, a stack nozzle, a condensate draining tube, and additionally there is a coaxial flue, at the same time the additional heat exchanger is installed in the cylindrical part of the coaxial stack, and near the base of the latter the condensate-draining tube is installed.
EFFECT: increased capacity of the boiler, higher efficiency as a result of arrangement of the second passage for smoke fumes and coolant heat transfer via a heat exchanger.
