Glass Boiler

Type AHEB4, AHEB6 and AHEB9 glass coil-type boiler is normally mounted in external circulatory loops using a spherical vessel as the main still. It should not be installed in the bottom of a flask or column.
The other types of glass coil-type boiler detailed on this page is again mounted in circulatory loops but as it’s nominal bore is same at the top and bottom, this unit can under certain circumstances, be installed one above the other to achieve multiples of the basic heat transfer area.
The maximum pressure in the coils is 3.0 bar g. The maximum differential pressure across the coils is 3.0 bars. Please refer to the performance data for glass coil-type.
PRECAUTIONS TO USE GLASS BOILER ARE AS FOLLOWS
Flexible hoses must be used on the coil inlet and outlet and must have sufficient fall to avoid the collection of condensate.
To avoid the possibility of steam hammer, the steam main should be adequately trapped.
