With the Vitomax 200-HS (type M73A) high pressure steam boiler, Viessmann meets the requirements of efficient steam generation. The permissible operating pressure extends from 6 to 30 bar. The output range extends from 0.5 to 4 tones of steam per hour. The Vitomax 200-HS is used in manufacturing industries, as well as food processing, fertilizer production, construction materials, paper, beverage, chemical and pharmaceutical industries, hospitals and refineries. Optionally, the high pressure steam boiler can be operated with light fuel oil (HEL), liquid gas or (bio) natural gas.
The spacing between the smoke tubes, as well as from the smoke tubes to the boiler shell and to the flame tube, are well above requirements. The shearing force on the end face floors caused by different linear expansion in the smoke tubes and the flame tube is therefore extremely low, guaranteeing a long service life for these steam boilers. The corner stays of the boiler are always arranged in pairs. As a result, the forces are distributed, reducing the stress in the component and increasing the service life. In every case, the values lie well below the limits permitted by the FDBR trade association.
Customer-specific requirements can be taken into consideration in the design of boilers in this series.
