Forced Circulation Water Tube Boiler - ferienhaus

Velox boiler is a water tube forced circulation boiler. It has a gas turbine driven air compressor, which compresses the air. This compressed air enters into the vertical combustion chamber, as result, high rate of heat release from the fuel, which increases the flue gases velocity up to the sound velocity. Get a quote

Combi Boilers | 3 Pass Smoke Cum Water Tube Boiler-

Combitherm boiler or is known among others as Combi boiler is a unique water cum smoke tube type design. It is the combination of both Water Tube Boiler and Smoke Tube Boiler where some tubes form the enclosed part of the external furnace in which water flows and rest of the tubes are placed in a shell in which flue gases flow.

Parat Exhaust Gas Water Tube Boiler - PARAT Halvorsen

The water tube boiler consists of finned tube or bare tube bundles mounted together in sections. The water circulates through the tubes and the extended heating surface on the exhaust gas side makes this boiler compact. The water flow is generated by circulation pumps and evaporation takes place in the boiler. The water/steam mixture is then separated in a steam drum or in an auxiliary boiler.
