Boiler for e.g. agriculture application, has combustion chamber receiving fuel material, and flues diverted in relation to flue gas stream and exhibiting double-walled formation, where inner areas are flowed from heat transfer medium

摘要

The boiler has a combustion chamber (2) for receiving fuel material. The combustion chamber is enclosed by a chamber. Walls of the chamber are supplied with a heat transfer medium (16), which flows through an outlet after heating of the medium. Heating gases (4) produced in the combustion chamber are supplied to a heating surface (23) downstream to the combustion chamber, where flues (26, 27) are diverted in relation to a flue gas stream (34) running in a direction of an exhaust gas furnace (25). The flues exhibit double-walled formation, where inner areas are flowed from the medium.
