High pressure hot water generators in double-flame tube design

HWO-D

Capacity Range
(according to DGRL 97/23/EU and DIN EN12953)

capacity up to 34.0 MW with light fuel oil
capacity up to 44.0 MW with natural gas

The SCHNEIDER-Three Pass Boiler HWO-D supplements the single flame-tube boilers in the higher performance range. The double flame-tube design offers economic hot water generation requiring a relatively small space for installation.
The special feature of the SCHNEIDER-Three Pass Boiler HWO-D double flame-tube design is the complete separation of the two combustion parts. The flue gas of the two burners flows, separated from each other, from the furnace through the smoke tube passes into the outlet chamber. Separation walls in both reversing chambers and the outlet chamber avoid any interference of the two flue gas flows. This is a basic requirement for faultless and low-pollution combustion and it also permits single flame tube operation.
