Hot air boiler VIGAS TVZ is designed for burning dry wood mass from sawdust to logs up to 35 cm long. Sawdust, shavings, chips and cuttings must be burned together with larger logs. The hopper content is sufficient for 6 - 10 hours of normal boiler operation.
The boiler is welded from steel sheets 4 and 6 mm thick. The inner shell of the boiler, which is in contact with the flue gas, is made of 6 mm thick sheet and treated with anti-corrosive spray. The heat exchanger is welded to steel pipes Ø57 × 4.5 mm. The combustion chamber is lined with fireclay bricks of 20 mm thickness. The casing is made of 0.8 mm thick sheet. Boiler insulation is made of NOBASIL material 20 and 40 mm thick.
