Indirect Fired Water Bath Heaters
Indirect fired water bath heaters are used successfully in hundreds of
utility, processing, and upstream oil and gas industry applications. Water bath
heaters are commonly used in applications where process temperatures do not
Typical uses include:
- Heating natural gas prior to pressure
reduction to eliminate frost formation downstream of expansion valving.
- Preventing hydrate formation in well stream
- Heating well stream fluids
prior to phase separation.
- Heating process streams to maintain fluid
viscosity at a minimum to reduce HP pumping requirements.
- Heating critical feed stocks
that require tightly controlled film to bulk temperature differentials.
- Heating turbine fuel gases to maintain a
given dew point temperature.
The indirect fired water bath heater consists of the following components each designed to meet specific
The heater shell
is an atmospheric vessel designed in accordance with API 12 K requirements. The
shell contains the process coil, firetube (combustion chamber), and heat media.
is commonly of the U-tube configuration. The tube is removable &
designed to efficiently transfer heat into the surrounding heat media and to
minimize flue gas friction losses.
The process coil
is a pressure containing part commonly designed in accordance with API—12K or
ASME Section VIII Division 1 code requirements.
The flue gas stack
is designed to provide positive flue gas flow (draft) by overcoming the
friction losses in the complete combustion system.
The heat media
is commonly a mixture of inhibited ethylene or propylene glycol and water which is
blended to a consistency to provide the proper freeze protection for a given application.
The expansion tank
is designed to reduce internal corrosion within the heater shell by keeping
the heater shell liquid packed & moving the wet dry interface of the expanding bath media from the
heater shell into the expansion tank. The expansion tank is designed to contain 100% of the expanded bath
media from a temperature of 40° to the maximum operating temperature.
designs & manufactures heaters with a wide variety of accessories to
meet customer specified mechanical & operation requirements. Including simple pneumatic controls to
